Fare Well, Nemo

Brief post today.

Nemo Departs

This past Spring/Summer, I thought I had sold Nemo (1997 Audi A4 Quattro) to our friend Garry. After repairing the driver rear bearing and replacing the axle with it, the power steering blew a hose and he lost interest. So, it came back. Truth be told, Nemo never left the driveway; Garry did the repair here. I figured I would do what was needed to get Nemo through smog and then figure out what to do. So, I repaired his exhaust, replaced the catalytic converter, downpipe and O2 sensor. I was ready to take him to Oregon DEQ when  the NewOldHouse purchase happened and so Nemo just kind of sat. Fast forward a few weeks and I get a text from Garry, now living in Idaho. His friend expressed interest. So, I shot some pictures and video with my phone and sent them on. 2 days later, he is here, with a friend, a truck and a tow-dolly. They crawled around on Nemo for a while, took him for a drive.... paid me cash and drove away with him. Just like that, the herd is thinned my one.

Mom Moves

With my Dad's rather sudden decline and then final departure early this month, my Mom lost the person who had eyes on her 24/7. Her health has been an issue for some time, so having her living alone in a somewhat basic assisted-living facility was no longer safe for her or the facility. So, she is moving to a stepped-care facility 4 blocks from here. That move is today (29-Nov). Since her space is significantly reducing, we will move her and her most treasured belongings to the new place. Everything else is moving here, so it can be gone through with heat and beverages and comfortable seating.

NewOldHouse Update

Since my CoViD battle ended, I have returned in earnest to the restoration of the NewOldHouse. When the flooring guys were here last Summer, they removed all of the 1/4-round. As they removed it, they clumped it by room and taped the clumps together. Unfortunately, some of that careful work was undone, and some of the 1/4-round went to the dump. What remains is semi-documented. I have been puzzling-out which pieces go where, re-marking them and then shooting them with BIN primer. Once dry, I set the pieces where they will be re-attached to the baseboard. Prior to priming, they get the nails removed and then a good cleaning. I have a small pile of un-matched pieces and a larger pile of not-yet-attempted pieces. I will be continuing this game next weekend.

Other than playing with 1/4-round, I resolved the canopy catastrophe, consolidating 2 damaged canopies into one viable one. You can see things are back to "normal" in the picture on the right, with the "Jerry" canopy restored. If you look closely, you can see stacks of 1/4-round under the canopy on the left (Phil). I have also cleaned, rust-converted and painted the heat vents. We decided that the original vents could be salvaged, and if they were painted a color that roughly matched the floor, they would sort of disappear into the wood floor. For the most part, this turned out to be correct, though I don't have a good picture to share.

The bathroom progress was temporarily halted by the discovery of the sub-floor damage. Boo crawled back under the house to see how extensive it was.. and it is really quite contained. There are 3 1x4 (sub-floor) boards that rest between the top of the beams and the wood floor which need to be replaced. But even then, the section that needs replacing is only between 2 beams, and the beams themselves are in great condition, showing no damage from the leak.

As part of the preparation for a bunch of mom's stuff appearing here, I tore down the living room stereo equipment and moved it out of the way. While this isn't terribly interesting stuff, it does further prove that life is either Tetris or Monopoly, and today it's Tetris.

With each passing day spent at NewOldHouse, it feels more and more ready for occupancy. Sure, we don't have a functioning bathroom yet, nor will we have a functioning kitchen for some time. Still, we believe that we will be moving into NewOldHouse by the end of January. I guess that's it for today. I know there isn't much car content these days; that is also true of my life, and I feel it. The sooner the house is ready, the sooner I will be back wrenching on Hapy. Thanks, as always, for following along-

If It Doesn't Move, Paint It (Final)

After weeks of spackle, caulk and masking, we were finally ready to shoot the interior of NewOldHouse. We would have arrived here earlier had we not digressed outdoors, but when the rains come, you need to have already gotten your wet/dry solved, or you will be doing it in the rain while everything gets wet. Anyway, today's post covers the final adventure in paint, and a few other things that happened along the way because.. of course.

Just as I completed the work described in this post, I tested positive for CoViD. I am living proof that living a hermit lifestyle is not a guarantee that you won't get CoViD. I have been going to a pizza place in Hillsboro for an open jam on Wednesdays as my only outing, so at least I know where it happened. I've been down nearly 10 days with it now, so progress on cars, the house, even my job is, obviously, halted. Good times.

The Walls Came Down

thar's a furnace in thar

For some reason, when the prior owners installed the gas furnace, they put it into the main living space. I thought it was because of the proximity to the chimney, but from the garage, there is a straight path to the chimney as well, and popping an exhaust through the roof would not have been that difficult. Instead, they put it into the dining area, and then... built walls around it. The new walls were, probably, a foot away from the furnace while the furnace was located 6 inches or so from the original wall. We couldn't figure out the thinking, but we didn't like the furnace location, nor the walls. With a plan to eventually move the furnace into the garage, I tore down the walls around it.

I took the time to remove the baseboards, the door trim, door frames and the doors. I removed the trim nails and collected these reusable bits onto the garage rafters. I then went after the drywall with a rubber mallet. I didn't want to make a huge mess, I just wanted the walls down. So, I loosened the drywall from behind and then pulled sections off with gloved hands. The refuse went out to the dump pile, and I turned to the framing. This was fun. I smacked the inner wall framing a couple of times with the long-handle sledge until the bottom came free. Then, I wrenched the 2x4 back and forth to remove it from the upper. One by one the inner pieces were removed, leaving the corner and the door frames. For the door frame-framing (the 2x4's that create the rough door opening to which the door frame is attached), I removed the header first, and then the side pieces could remove in a similar fashion to the middle framing bits. Then, I took out the corner. Again, this was simply smashing with a sledge and prying with a wrecking bar until they gave way. Most of the corner came out in one large section. The ends nearest the original walls were next, and the top plate came down with those, leaving the footer. the footers were set into the original hardwood floor with 3-inch-long nails. To get to those, I carved out the top of the 2x4 with a screwdriver and then leveraged the top of the nail enough to fit the wrecking bar underneath. Some subtle pressure later and the nails were out, and the footer was out. The space seemed much larger.

 

More Masking

walls? what walls?

With the furnace now exposed, I could paint those original walls, but I did not want paint on the furnace or the nicely finished original wood floors around it. So, I spent a couple of hours with paper, plastic and tape covering everything except the venting on the front of the furnace and the exhaust to the chimney. I left those for actual paint-time because I want to keep running the furnace until then.  I know that the exhaust would meld or burn anything I wrapped it with and the front of the furnace needs to be open when in service. On paint day, I turned the furnace off for the shoot, and covered the exhaust with film, the front of the furnace with a sheet of waste cardboard.

Prime Time

Nemo at NewOldHouse

After the walls were washed and I had checked and rechecked that everything had been masked, I had considered priming everything. I decided that it was probably excessive, especially considering how clean the walls were once Boo was done with them. Still, there were some stains, so we got some some Kilz2 to cover them. The Kilz2 does not cover odors, and there were still some remaining cat smells. So, I thought about getting some original oil-based Kilz and shooting the lower 3 feet of all the walls to try to contain that. Again, overkill. I concluded that the cat urine smell was probably not in the plaster, it is probably coming from that space between the hardwood floor and the baseboards. So, I decided that after we stripped the masking out, I would shoot that space with some enzyme-based cleaner (like this).

While I did not prime everything, I did prime the popcorn ceilings in the "new addition" bedrooms (built in early 60's) out of concern for how much paint they would suck up. I shot the stains as well as the original pink paint that appeared where I removed the walls around the furnace, and the area in one of the addition bedrooms where a shelving unit had been removed. Most of these areas were reachable without having to move the sprayer. I needed to move it once, from the rear of the house to where the furnace is. Before I cleaned up the equipment and put everything away, though, I took the operation out to the now-clean future tool/parts shed and shot that entire interior with the Kilz2. It was bare wood, and I figured painting it white would help illuminate the space once filled with shelves and some lighting. The shed has a high shelf/storage area so unlike my spray adventures so far, I needed to work from a ladder to hit the shelf and ceiling well. Even still, this spray was fast, and since I had started early in the day, I felt confident that I could get most of the interior spray done.

Shooting for Good... Enough

tool shed primed

Our original plan was to buy really good white exterior paint. At $300US per 5 gallons, we changed our minds, and bought generic indoor/outdoor eggshell white paint. The house is still white, but we may need to paint again sooner. So what? There is quite a bit of siding that needs replacing, so little harm done. Fast-forward a few weeks and Boo and I got to a similar conversation about the interior paint. I painted our current house interior with an eggshell "Brazilian Tan", which is beautiful, but the house was already dark and even though the Brazilian Tan was lighter than the paint it went on top of, it's still pretty dark in there. Even in the summer. NewOldHouse is not in perma-shade like the current place it, but we decided we want it to be super bright.

We talked about painting the walls with some color, but the main rooms have coved ceilings, making it difficult to draw a line where the colored wall would meet a white ceiling. Many older houses have a picture rail that will draw that line for you. Since we don't, and we were not sure what to do color-wise AND draw-the-line-wise, we went with.... generic indoor/outdoor eggshell white paint. Sound familiar? Yep, it's the exact same paint. Why keep all these tins of touch-up paint when you can keep only one? LOL. I'm sure this paint will be acting as a primer for the next coat (that has a color), it's just a question of when. For now, white walls go with any decor... well... they will go with ours anyway.

Paint On!

furthest room shot

With the stains and popcorn ceilings primed, I switched over from the Kilz2 to the eggshell and grabbed a quick bite. My time shooting Zed taught me that once you start, you really can't stop unless there is a clear line where the painting can stop. I also remembered that ventilation is super important, so I set a box fan in the open front door (blowing out), and had the kitchen windows wide open. I wasn't sure how long the Kilz2 had been drying on the ceilings in the back bedrooms, so I started with the shed. This gave Boo the most time remaining to clean whatever walls or ceilings we had not yet cleaned. By doing the shed first, I also took advantage of the little daylight Oregon has at this time of year. The shed painted like it primed, though I fogged (light passes at a greater distance) some of the wood panels after I completed the shoot, trying to get consistent coverage. In the end, most of the walls will be covered with shelves, so the handiwork won't really show, but I have a hard time half-assing things.

Once the tool shed was painted, I moved the sprayer into the furthest new-addition bedroom, and shot it completely. I started with the closet and then the ceiling. Then, I shot the window frames and finally the walls and baseboard, working my way towards the doorway. This kept the paint hose from hitting freshly painted walls or trim, and the sprayer in one spot for the duration of that room. Once the rest of the room was done, I moved the sprayer into the next bedroom and shot the doorway and the door. Last, I cracked the large window to let some fresh air in.

 

front living room shot

I sprayed the next bedroom following the same pattern: closet, ceiling, window frames, walls and baseboards. Again, I backed my way out of the room, moved the sprayer and then shot the doorway and the door. I continued this pattern, backing down the rear hallway, shooting the ceiling, then walls before moving the sprayer into the one original bedroom. Unlike the other 2 bedrooms, I decided that shooting the window frames early effectively restricted the amount of light I had to work with. So, I shot the window frame after I did the baseboards. Similar to the other rooms, though, I left the space around the doorway for after I moved the sprayer, and shot that area last. After cracking the window, I hit the hallway, turned off the furnace, removed the thermostat and then shot the hallway, avoiding the cold air intake.

 

At this point, it was past 430PM, so twilight was setting in. Without meaningful light, my shoot was done for the day. So, I popped the thermostat back in, turned the furnace on and cleaned up the sprayer for the night.

 

Second Verse, Same as the First

main room, start of day 2

When I returned the following morning, I walked the area which needed to be painted. The furnace was not 100% covered yet and in the middle of the main space Boo and I had set out all of the built-in drawers and the pieces of my desk to get painted with the rest of the house. Navigating these items while shooting the ceiling was not a good idea. So, I moved the drawers, desk cabinets and shelving into the front bedroom to get shot. Next, I looked at the ceilings; we had not quite finished washing all of it, so I TSP'd a section. Last, the doorway into the partially demolished kitchen was unimpeded. Everything that had been setting in the main room for our workday comforts (camping chairs, snack cooler, etc) were in the kitchen too. So, I added overlapping plastic sheeting over the doorway, so overspray would not blow onto our creature comforts.

Ready for another shoot, I donned the old white overalls, wrapped my head with a white T-shirt, set up the sprayer and got after it. I started with the walls around the furnace, so I could unmask and re-start it at the earliest moment. I moved through the space anti-clockwise, shooting the eating nook first, then the main living space and finally the den-like area directly rear of the living room. Satisfied, I moved the sprayer into the front hall and shot the drawers, etc set up in the front bedroom, completing the spray. End-to-end, it was probably around 6 hours of shooting plus a few hours of cleaning / prep on the second shoot day.

 

Clean Your Tools

main living space complete

To clean the sprayer, I put about 2 gallons of water into a clean 5 gallon bucket. Before I dropped the sprayer pickup tune into it, I hosed the pickup tube off with the garden hose. Now somewhat clean, I put the pickup tube into the water and the priming hose back into the paint. I primed the machine until water was coming out the priming hose, and then I shifted that hose into a recently emptied 5 gallon now-slop bucket. I continued to prime until the priming hose was running clear. Then, I switched over to "sprayer" from "prime" and did the same thing: shot into the paint (reversed the tip) until it started to get watery, then switched over to the slop bucket. Once the gun was shooting mostly clear, I shut things down, released the pressure and took the pieces into the garage sink for cleaning. Since most of the paint was already run out, cleaning with running water and soap was relatively quick. Paint needs warm air, so I set the furnace to run the fan all night and I left the box fan running as well, to help speed the drying.

 

Strip, Lights

further room done

Boo and I returned the following day and started pulling the masking off. For me, the most important thing was that we didn't have many thin or bare spots. I only found one 2-foot by 3-foot bare spot on one ceiling, and I decided to fix it with a flat-nap roller rather than pull out the sprayer. Otherwise, the coverage looked good. Sure, there were some heavy spots, and I attribute that to the hard-to-see from lack of light. Regardless, we pulled the paper and film from the windows, light fixtures and floors, rolling it into a big puffy pile as we went. We discovered some spots where the tape did not hold, allowing for paint to get on the floors, but overall, the finished product looks really good. Once the paper was up, I cleaned each light fixture and mounted it, with bulbs.

This was a huge milestone. With the interior of both the house and the tool/parts shed painted, we can start moving non-essential things (like Nemo, the Audi A4 B5) over to the NewOldHouse. Nemo drove over with no issues, by the way. We need to source, paint, measure, cut and install 1-inch quarter round pretty much everywhere the new painted baseboard approaches the wood floor, though. If you look at these couple of pictures, you can see the gap. I expect we will be doing the 1/4-round a room at a time so it doesn't become a huge undertaking. Of course, at one room at a time, it could take quite a while to complete. Once we do it, I'll post on how we went after it.

 

Because moving is really only interesting to the person who is moving, I won't post on it. If something else happens that might actually be interesting, I'll post on it. Otherwise, until after the move, thanks, as always, for following along-

Nemo Time

Remember Nemo? He's the 1997 Audi A4 (B5 body style) that T bought and wrestled with for a few years, replacing the clutch and brake master cylinders as well as the clutch slave cylinder and repairing so many other things. I also did a TON on this car (just what I posted on), so the fact that he needed more was a little, well... frustrating. When T moved to LA, he signed Nemo over to me, and then we thought we had sold it within the family, after replacing the driver-side rear axle and wheel bearing. Only to have the power steering fail... ending that transfer. So, Nemo has sat in my driveway. He has many little issues: a water leak into the driver's footwell, a broken front passenger window regulator, a big hole in the exhaust, a sunroof that won't open, some other little missing bits, and, of course, the failed power steering. Today's post covers my efforts to resolve enough of these items so he can be registered and driven again.

Before I begin, the sanding on Zed continues. I will post an update next week, hopefully, with some meaningful progress. In the meantime, I have slowly crawled along with Nemo over the last few weeks, so I thought an update was in order.

Water Leak

Schmidty sniffing the ECU box

I believe I solved the water leak when I discovered that the plastic box that holds the ECU was not entirely attached. There is an obvious nut on the outside, near the driver fender. There is a second nut inside the box closer to the engine, back near the fire wall. Underneath the ECU, is a large (like 1 inch by 3 inch) rectangle opening into the footwell. This hole has a gasket, but if the box is not held down firmly enough to engage the gasket, water which finds its way under the box (which is a for-sure here in rainy PacNW) will run straight into the driver footwell. In Nemo's case, the inner nut was simply not there. I found one, and snugged it down. Problem solved. I hope.

Accessing the Exhaust

big old rusty dirty cat

The big hole in the exhaust has been a major pain to solve. The aftermarket cat-back exhaust installed by a prior owner did not have any support between the end of the header and the rear axle. It did, however, have a section of flex-pipe immediately after the header, creating the car's lowest point. So, when the car drove over speed bumps or dramatic driveway transitions, it was the flex-pipe which hit the ground. Eventually, that flex-pipe failed. With the failure came a Check-Engine-Light (CEL) preventing a DEQ pass. To resolve, I removed the catalytic converter, downpipe and mid-pipe so I could replace the failed flex-pipe. This removal is challenged by the usual issues with exhaust hardware, but the Audi has additional things, like heat shields, in the way. So, the air box needs to come out, and the passenger front wheel comes off so you can access everything. Even then, Audi engineers seem to like to use different fastener types and sizes pretty much everywhere. Of course, the owner plays a role here too.

Cat Away

cat out

After trying a wide array of tools, I ultimately needed a hacksaw blade to cut through the rusted bolts between the catalytic converter and the down pipe. The PO had used regular steel fasteners to attach them, and even after multiple days of spraying Kroil on them, they were rusted tight. I cut the bolts, sending the hacksaw blade between the opposing flanges, at least far enough for the bolts to snap in half when I applied torque to one end with a socket-wrench. This took some time and patience, and because of how the bolts are oriented in the engine compartment, I was only able to sever 2 of them. This loosened the connection enough for the downpipe to rotate on that last bolt, allowing me to pull the 2 out the top of the engine as a unit. I cut the other bolt off, separating the 2 pieces, on the driveway. Holding the downpipe still with my boot, I cut the lip of the flex-pipe from it using my angle grinder.

Before I started, I ordered a brand-new catalytic converter, thinking that the one that was on there was 10+ years old, and of unknown working condition. After spending many hours cutting through rusty bolts with a hand-held hacksaw blade, I do NOT want to do this R&R again even if the fasteners are new. So, I'm grateful I made that purchase decision. After I got the cat on the ground I could see the Audi symbol on it, so either it was replaced at a dealer a long time ago or it was the original. Either way, at almost 300k miles, it is unlikely that catalytic converter was still doing its job well. Well enough to pass Oregon DEQ? We'll never know. Besides, the old bolts are rust-attached to that old thing, so re-install would have been considerably challenged.

new cheap hanger

On the other end of the hole in the exhaust, I removed the mid-pipe (2 bolts), cut off the remains of the flex-pipe with the death wheel and re-installed the mid-pipe. I added a support immediately behind where the flex-pipe-to-mid-pipe joint will appear so it is held up and away from the ground better. For the support, I got one of those cheap bolt-on hangers, attaching to the rear of the transmission through an unused bolt hole in the rear of the case.

Cat In

Moving back up front, I installed the new cat first, re-introducing the original O2 sensors as I went. To the cat, I added the down pipe and then finally connected the down pipe and mid-pipe with the flex pipe, fitting things together with clamps and exhaust dope. 

I got Nemo back on the ground to take him for a test spin around the usual neighborhood track. Before backing him off the ramps, I checked the exhaust for leaks, and it looked good, with a little puff of smoke coming out the tailpipe. The exhaust sounded much better, and it doesn't leak. So, around the block we went. It still hangs low, but it is fairly well tucked up under the body compared to before. The rear end ride height is so low, there is a near-constant threat of bottoming out. I will need to resolve that soon. He drove great; plenty of pull from the turbo, and the exhaust was much quieter than he had been on the last test drive. Clearly, the noise and smoke is going out the tail now. I thought I might have heard the rear passenger wheel bearing, though, so there may still be more adventure coming. And, yes, you can drive a car with failed power steering; you just need forearms like Popeye if you need to turn the wheels when the car is not in motion.... like to maneuver it out of a shop bay into the driveway through a 9 point turn. 

Oh Two

Oh Nemo.... O2

Unfortunately, the CEL is still on, with a code (P0134) indicating that the upstream (before cat) O2 sensor is bad. When I considered the smoke puff out the tailpipe when it was sitting on ramps, this makes sense: if the computer doesn't know the air-fuel mixture sent from the O2 sensor, it sends a richer fuel mixture to protect the engine from being too lean, which is why a failing O2 sensor is a DEQ auto-fail. So, I ordered a replacement upstream O2 sensor and now I'm waiting on shipping before I take another test. Since the error code did not include a code for the downstream O2 sensor, one might think that the old catalytic converter was still working. As I pondered this, I picked it up from one end, and I could hear dust settling through it. So, even if it wasn't toast, it was soon to be. When the new O2 sensor arrives, I'll slap it in, clear the code and go for a spin. If the CEL doesn't return, we may take him through DEQ before the next update. 

That's it for today. Like I mentioned at the top, the sanding on Zed continues. After sanding him smooth with the 320-grit, I did not like some of the orange-peel effect I found underneath, so I sanded the primer end-to-end with 320-grit again. Thanks, as always, for following along-

Shade Tree Set-up

I received questions about what "Shade Tree" is and what my set up is. I figured, since I am still completing Bondo cycles on Zed, the 1979 Datsun 280ZX, I would post some pictures of my space. Since I am approaching the end of the Bondo cycles, I'll share what I have learned as well.

Zed Bondo Update

Yes, I am still doing cycles with Bondo, but I am much closer to complete. I have learned a few things the long-hard way. I hope these are helpful so you don't make the same errors I did (and sometimes still do). It took me many many hours of failures to learn this, though I am sure there are folks reading this who knew all of it already.

Let's start with how to discover a spot that needs to be fixed. I started with feeling with my hands by moving them fast and slow over the paint-stripped body. A painted surface is much better for seeing issues, by the way. Once you find the spot, you need to determine how large a patch you need to lay for it to become flat. For that, I now use chalk, drawing a circle around the malformation. This allows me to easily spot where to slather on the Bondo without having to re-evaluate while the Bondo is mixed. That leads to my next learning: Bondo viability duration.

Bondo is only usable for a handful of minutes after the hardener has been mixed in. Some say 3-5 minutes. So, rather than making a big blob of it, I make multiple super-small batches. By super-small, I mean like up to a cup of Bondo at a time. From the can, I slap it onto a small sheet of glass for mixing with a spot of hardener that's maybe the size of a US$ dime (or smaller). Once thoroughly mixed into one consistent color, I go after the spots I have marked. I now apply more than what is needed to fill the imperfection as Bondo shrinks a little bit when it dries and you need something to sand away to get it perfect. Once the consistency of Bondo starts shifting from smooth-like-sour-cream to cakey-like-cookie-dough, stop applying it, toss it out and make more. Bear in mind, Bondo will adhere to bare metal and some primers, but not paint. So, your surface might need to be sanded down before you start applying.

This 2-step process is great for getting the area set up, but similar to "you can be a mediocre welder if you are a good grinder", the key to Bondo is sanding. I have tried all kinds of different things to get my panels smooth, and in many cases I removed too much, if I had even applied enough. Assuming I have enough Bondo, removing too much is the next issue. Rather than go through what hasn't worked, I'll focus on what has.... other than: do not use your hands/fingers if you want the contour to be correct. Use a block; you may think your fingers know how to find that flatness. They can sense it when you're checking your work, but they can't push sandpaper to it. Your car, your choice.

First, I have an 8" sanding block with a worn-out 400-grit paper on it. I cut down sheets of 150-grit so I can hold a square with my fingers around half of the sanding block. So, half of the block is 150-grit and half is 400. I try to keep the 400-grit side furthest from the target Bondo and the 150-grit side in the Bondo as much as possible. This way, I am not agro-sanding on areas of the body that are outside the Bondo, while also using that body contour to influence the cut-down of the Bondo with the 150-grit. Obviously, the 150-grit exits the Bondo area some, and it needs to, for feathering the edges. All the while, in the front of your mind know that you are attempting to get the dip-filled-with-Bondo to disappear so the panel is completely without blemish.

Sometimes, for an especially rough area, I will use a worn down piece of 80-grit instead of the 150 to get started. This is simply to accelerate my progress, and I'll switch back to 150 before I get too far. The 80 is just to take that top edge off so the 150 will bite a little bit more. 

Once I think I have the panel smooth, I will use the 400-grit block (without the 150 wrapped) and go over the entire area. Then, I will feel for edges and contour. If necessary, I'll return the 150-grit to half of the block and sand some more. Using 150-grit takes much much longer to sand than the 80-grit, but I have not over-sanded one area since I switched to the 150 as the main contouring grit. Your car, your choice.

Once I got the worst of it done, and many of my old areas corrected, I needed to check the work. So, I shot some automotive sand-able primer on the repaired spots as a guide coat. I would then sand these areas down with the block. I repeated the Bondo cycle where needed. Often, a small imperfection in the Bondo itself (like an air bubble) will force another cycle even if the overall panel is now flat.

At the time I took these pictures of Shade Tree, I had completed the doors and rear hatch. That's why they do not appear in the pictures; they are stowed in the garage until I'm ready with everything else (fenders, shell and hood). That's right; I do not intend to do any more Bondo cycles on those panels.

Shade Tree

I alluded to this concept in my last post. "Shade Tree" is where my kids and I (and anyone else, for that matter) hang out with our cars, making improvements or repairs. I added 2 10-foot x 20-foot Harbor Freight car ports last Fall to extend the car-play season into the rainy season. It turns out, these canopies have made summer car efforts much more pleasant as we are now in the shade. Between my smattering of tools, we can work on 2 or 3 cars at once, and with the lot couch and camping chairs, there's seating when you want to take a break. We have twinkle-light strung up to extend the work day past dark. This is especially useful between the Fall and Spring equinox here in the Pacific NorthWest when it feels like daylight only lasts a handful of hours.

There was a time when I wanted to rent a warehouse and make something like this available to the public. I thought of all the people out there in situations like I had been: using a curb as a ramp to change my oil, getting hassled by apartment management because I opened and then left my hood open to change sparkplugs, or imposing on a friend who had a driveway to do something, and then worrying about that coming between you. I know some folks who have a significant other who does not approve of the mess that is created during the work, so they don't work on their cars much anymore. That's just sad.

Owning a car is already expensive with insurance and fuel. When you add in having to take your car to a mechanic, even for simple things that you can do yourself... simply because you don't have a place to do it? Well, that makes owning a car a class thing, and that's not right. Sometimes, you simply need a car. Maybe mass transit doesn't get you to where you work, and paying to Uber or Lyft every day takes too much of your income. I know. I used to paint new-construction tract houses. By definition, there was no mass transit, because the new construction was going where there used to be a farmer's field. That's just one of 100's of possible examples for why we have our cars. And that was why I wanted to create Shade Tree. So we could keep our gotta-have-it cars running (and a place to clown on our projects) without the hang-ups. Unfortunately, this idea came right around the time that pot was legalized in Oregon, driving up the price-per-square-foot for warehouses almost overnight because the now-legal growers snatched them all up. I could not make numbers work so it could remain cost neutral, much less make any profit, without creating a cost structure that I wouldn't want to pay if I were a consumer. 

So, instead, I use my driveway.

That's it for this week. At my current rate of progress, I may be ready for the final primer as early as next weekend. I know I have many bits (hinges, mirrors, etc) to locate, prep and prime as well, but once done, we will be talking about base paint soon thereafter. Thanks, as always, for following along-

Nemo Re-Assembled

I think this will be a quick post. In my last, rather lengthy, post about Nemo, I described the effort to get him running again. Today, I cover the electrical mop-up and the other little bits to get Nemo ready for regular use... by someone. While this is barely post-worthy, the wiring fix did take me a few hours, so in a way this is just documenting how I spent a Saturday. Besides, the weather has turned too cold to spray primer or paint, so Zed sits waiting.

Car-Toys Vent

I will start with a predictable slam on the hacks at Car Toys. Recall that when they replaced Nemo's stereo, they were directly asked/told not to cut up the wiring, rather to use a pigtail. With a generic response of along the lines of "we'll do it right" wink/finger-point, they did exactly what no one wants a radio installer to do: cut wires off of a harness plug and then direct-wire a new stereo into those bare wires. So, I give them a "that's not right" glower/different-finger-gesture. All-told, they cut the 8 speaker wires, switched and steady power, ground, power antennae and illumination. The part I don't understand is why they do not have a cache of pigtails for common cars. All VW's and Audi's from, like, the mid-80's thru modern cars use the same 2 8-pin female plugs... one 8-pin plug for the speakers and one 8-pin plug for the power, illumination, etc. The corresponding male pigtails run for, like $10US on eBay, and since they plug right in, the install is faster, while also cleaner: at a workbench, the custom pigtail for the new stereo can be wired into the Audi/VW standard male pigtails. Then, you take the stereo head-unit and the cable to the car, plug in each end and you're done. Cleaner, easier, faster. Instead, Car Toys does it lazier, longer, stupider and uglier... and much harder to undo.

Stereo Wiring Un-Hack

With the center console fully opened up, I had great access to the great wire hack. I started with the speaker wires, mostly because bits of the CarToys wire-extensions (1 each purple, grey and green) were still attached to a few wires post-theft, so I could tell what they used to be used for. Once those 8 wires were sorted, the remaining wires were much easier to isolate. The only difficult pair were the switched and steady power sources, because both were plain red wires. A simple voltage test (one had 12V and one didn't while at rest) resolved that. Yes, there was a hot wire bouncing around back there. Once the pigtails were wired up, I zip tied the wires into a cable on either side of the wire butt-joints so any gentle pulling would not cause a wire joint to separate.

Climate Control and Console Re-Assembly

With the loose wires sorted, the center console already looked 100% better. I continued the re-assembly by plugging in the climate control unit. While this has 4 plugs, they are each slightly different sizes so they can only go in one way. Once plugged in, I slid the unit into place and threaded in the Torx bolts to hold it in. Then, the console cover can snap into place. 2 8mm Allen head screws later, the center console is together again. I take satisfaction in seeing the stereo plug through the hole where a stereo should be. I may pick up a cheapy clearance stereo from Crutchfield to completely close the loop... and that hole.

Kick Panel and Re-Lo

All that remained was putting the lower dash panel back on. This panel is held in place by 3 screws: one at the bottom of the fuse box frame and 2 in front of each of the driver's knees. The fuse box frame screw is easy to get to and easy to manage. The 2 in front of the driver's knees, however, require some gravity-defying. I do not know what kind of fastener was originally used; Nemo has slotted bolts. These bolts need to be balanced on the end of the driver and then tilted over about 30* to find the hole in the panel, and then the matching hole in the dash. While this is not hard, it can be frustrating. Once bolted tight, the holes are covered with small plastic bits that snap into place.

Just like that, an interior that looked like it was at a junk yard is re-assembled and looking sharp again. I juggled cars at this point, moving Nemo into a more remote spot, out from under the carport. As before, he started right up like he hadn't been un-start-able for weeks. The juggle created the space needed to get Oliver out for some Summer driving. I did discover, however, that Nemo's front passenger window I replaced also had the front window tracking mechanism damaged when the window was smashed in. So, the window does not go up and down anymore. I will need to hit the junk yard again, to source a replacement window track thing. Neat. I do like going to the junk yard, though, so maybe I'll find some other stuff we need while I'm there. In the meantime, Nemo's air conditioning blows nice and cold, so a stuck window doesn't mean discomfort.

That's it for today. Thanks, as always, for following along-

Oh, Nemo

Today's post covers my challenges with Nemo's electrical and computer system simply trying to get him to start, or maybe a signal on the OBD-2 port. The car-work hours that I did not want to spend sanding on Zed, I spent doing this... until this took over. Yeah, I know. I could use another hobby.

No Start

Like so many issues with these old cars, our challenges with Nemo started with him not starting. His battery had been sitting on a trickle charger all winter, but I had left his hood cracked to make room for the alligator clips, so this ultimately was self-inflicted. Love those. But, the path we took to get there was interesting. Nemo is sitting under the fabric carport blocking a garage door. Behind that garage door sits Oliver, the 1978 MGB convertible, that I would very much like to be road testing and otherwise driving around. So, enter my motivation for moving Nemo. Insert key, turn ignition to "RUN". I see some familiar idiot lights, including the battery, oil and check-engine. Turn to "START" and he rev'd but would not start. I went around to the tailpipe and could not smell gas, so I start with the assumption that it is fuel delivery.

Before I did anything else, I considered what I experienced when I turned the key to "RUN". I did not hear the fuel pump cycle. I did not hear the radiator fans kick on. So, something is not getting the "RUN" signal. So, I pull out the UltraGauge and plug it into the OBD-2 port. I get a never-ending "scanning..." message. Well, that's not good. I double-checked the UltraGauge in Hapy, and the computer linked within a few seconds. Okay, we have trouble with Nemo's diagnostic system which could prevent a start or we have multiple things going on. With this car, the latter is probably true. First, I tried to isolate the OBD-2 issue, and kill many many hours doing so.

OBD-2 Issue Diagnosis: General

The early B5 versions of the A4 had some interesting 1 or 2 year only issues. One of the oddities around 1997, when Nemo was sold, was the engineers choice to integrate the stock stereo with the "K-line": the signal processing wiring between the computer, many components and the OBD-2 plug. In these late 90's cars, it is the K-line you are subscribing to, not the more modern "CAN BUS". Okay, cool. There are many modules plugged into the K-line, but they are all in parallel. the diagnosis theory goes that when you get no signal on the K-line it is because one of the modules is faulting out, grounding the K-line. Once you can identify and remove the faulty module, you will get a signal on the K-line. You will probably get a failure code for that module, but you will at least get a signal. So, away we go, trying to figure out what modules are even on the K-line, and then isolating them.

OBD-2 Issue Diagnosis: Radio

The stock radio wiring was unceremoniously cut to pieces by the idiots at Car Toys when they installed an aftermarket stereo. Based on the wiring diagrams I have found and the commentary on the interwebs, I am not sure this car actually had that K-line-in-the-stereo thing. I did check the wires for the right color combinations, and for wires that were the correct colors for the K-line. I was unable to find them. There are, however, many wires sticking out of the hole where the radio used to be... before it was ripped off in Eugene. I intend to re-integrate an original plug before I put all this back together, but that's another day. I moved on to the next possible culprit: the climate control system.

OBD-2 Issue Diagnosis: Climate Control

found in climate
computer

The climate control system in these cars is another little computer. In some models, it is held in place with a couple brass clips. In Nemo, I had to remove the center console cover plate / face and found 2 Phillips screws holding it in. Once threaded out, the unit removes through the front. I unplugged the unit and checked the OBD-2 for a signal. Nope. I did, however, find a soda/beer can pull tab inside it (picture on the right, here, laying on the carpet after I removed it from inside the climate control computer thing). So, that was interesting. Next.

OBD-2 Issue Diagnosis: ABS (Brakes)

The fine folks on the interwebs have found that the ABS sometimes causes K-Line problems. The way to identify if it is the problem is to disconnect the plug. The ABS unit is on the driver (left) side, next to the washer bottle. You simply pull up on the silver metal tab and the plug lifts out of the socket. I found a piece of electrical tape floating around in there. Another question-mark from the prior owner. Neat. I checked the OBD-2 for a signal. Nope. I shot the socket and the plug with DeOxit and left it disconnected for the rest of my tests. I figured I might as well leave it better than it was (DeOxit, not leaving it unplugged). Next!

OBD-2 Issue Diagnosis: Dash Cluster

Moving on, we consider the dash cluster. The entire thing is held in by 2 Torx-head screws from the front, hidden behind a cover plate just above the steering wheel. Pull the cover plate, remove the screws and it pops right out. I unplugged the various cable plugs and checked the OBD-2 again. Nope. Grr... Next!!

OBD-2 Issue Diagnosis: ECU

example A4 ECU 

It seems like every system on the engine that has more than one wire into it delivers some signal to the computer. So, this seemed like the next logical step. I figured if I could get a signal after unplugging the small plug on the ECU, I would have shown that the issue is in the engine compartment and I could put everything in the cabin back together again. If the issue remains, then it could be the ECU. So, I disconnected the small plug from the ECU and we still didn't have a K-line signal. Grr...

So, I plugged the ECU, ABS and the dash cluster back in, turned the key to RUN and heard the click-snap of some relays firing, but no fuel pump nor fan spin. I could not remember if I heard the relays before, but this changed my thinking. If at least some of the relays are firing, then the ECU is telling them to. If there is a Check Engine Light, then the ECU must be at least partially working. Perhaps the K-line / OBD-2 issue is completely unrelated and this is just a simple fuel supply issue. So.. new plan: get the fuel pump to fire.

Fuel Pump Test

As is so often the case in laboratory settings, the pre-work for the experiment is where all the time is taken. Such is the case here. I started by removing the plate covering the fuel pump. This sits behind the rear seat in the trunk on the passenger (right) side, and is held in place with 3 very short Phillips screws. Once the plate is removed, you can see the top of the fuel pump. There are 2 fuel lines, one supply and one return, and a single electric plug. I found that slightly wiggling the plug allowed it to pull off the pump. YMMV. Once removed, you will see 4 pins. 2 of them are for the fuel level and 2 are for the pump. I started my tests with basic resistance and continuity-to-ground. Things seemed fine, so I shifted focus to test-firing the pump by applying 12V to the pump.

This is where the experiment set up took some time relative to the actual test execution. I ran a pair of wires from near the battery (not hooked up) back to the fuel pump. At the battery, I taped 10A fuse to the "red" wire and alligator-clipped the other side of the blade to the positive battery post. I alligator-clipped the "black" wire to the negative post. Back at the fuel pump, I applied the red and black wires to the fuel pump and it fired right up. I held the wires there a few second to demonstrate that it would not just run for a second and die. So, we have a good pump, but the pump won't fire from a relay signal. So, next we check the voltage from the relay, after we put the experiment wiring away.

Fuel Pump Relay Test

A4 Fuel Pump Relay

Back up front, I took a red wire, stuck it into the voltage-supply pin in the wiring plug at the fuel pump and tossed the other end through the cabin, over the outer edge of the driver seat. My plan was to compare the voltage sent to the pump at the pump. Since the relay only pops for a second when you turn on the ignition, I had to have my test equipment near the ignition key. I stuck my black lead against the metal fuse box mount, held the red lead against the wire I tossed through and turned the ignition to "RUN". I got 5V. I checked other spots around the fuse box and got 13V, so I started thinking that the relay was bad, dropping the voltage from 12/13V to 5V which, of course, is not enough to run the pump. So, I swapped out the relay... and the fuel pump still would not run. Great. I concluded that the 5V I read was actually the base charge for the fuel level sender and not the supply for running the pump. 

So, I checked the voltage at the supply-side of the relay: 13V. I jumpered across the relay pins, and the pump fired up. So, we're back to the ECU is not sending a signal. Fearing it is the ECU, I went looking for any other reason. I recalled that when Dot (the white 2000 VW Jetta 2.0 which broke the timing belt) failed, one of the theories for not starting was a crank position sensor. The thinking is that if the ECU doesn't know where in the revolution the crank is, it doesn't know when to fire, so it doesn't try. It is not as clear whether a failing crank sensor would prevent the fuel pump relay from getting a signal from the ECU, however. As much as I have tried to avoid it, it felt like I was sliding into just-swap-parts problem solving. At $35US for the least expensive part-to-swap (crank position sensors start closer to $60US), this can get needlessly expensive very quickly.

Crank Position Sensor (CKP)

A4 Crank Position Sensor

I have mentioned before my belief that the Audi engineers are sadists. Only someone who takes pleasure in other's pain could arrange for replacement items to be so hard to get to. Case-in-point: the crank position sensor. The crank runs the length of the block (obviously), so given a blank canvas, an engineer could potentially place a sensor anywhere along that axis. Chosen location? Directly under/behind the oil filter so you either have to remove the oil filter (forcing an oil change, which arguably is due) OR you need to perform contortions to get an Allen-head wrench in there. If you go this route, consider that the further the bolt comes out, the closer you get to the oil filter. At least there is only one fastener. These sensors have a long lead on them that plugs into the engine harness... behind the coolant bottle. In Nemo's case, this plug was fairly easy to get to. There are methods for testing the sensor, of course.

The Audi/VW sensor has 3 wires, from pin 1-3: power | signal | ground where the power and signal connect to the ECU and the ground finds its way to the chassis. To test, 12V and ground need to be supplied to the sensor plug (once disconnected from the harness) and a multimeter checking the signal wire for an AC wave signal while the engine is turning. No signal = bad sensor. Since no local shops had a CKP, I returned to sanding Bondo in Zed while I waited for the part to arrive.

Once I had the part in hand, I checked the resistance between the pins. I got 500ohms +/- between the middle pin and one of the outer pins. Using that as a baseline, I swapped out the CKP and then tested the one I had just removed. Same resistance. So, I concluded there was nothing wrong with the old one and put it in the stash of A4 spare parts (with the fuel pump relay).

ECU Swap

At this point, I had run completely out of ideas fo4r why the ECU was not sending a "go" signal to the fuel pump relay. I hit the local junkyard looking for a just-dropped-off A4 to scavenge the ECU. None of the A4's there had the right ECU, but I did get an ECU box cover: Nemo's had a good-sized hole in it where I thought water might have entered. Without another option, I hit eBarf and found an ECU with the same part number as the one as was currently in Nemo at a salvage yard on the East Coast (with a 30 day return policy!). Hopeful, I swapped out the ECU's which consisted of pulling out the big plugs in the back of the old and plugging them into the new one, since the box was still lid-less. I had some concern that energizing the ECU could fry it if the underlying condition still existed.

Still, I turned the key to "RUN" anyway... and heard the radiator fans and fuel pump cycle for a second before shutting off. This was how things used to work. So, I turned to start and he fired right up. I have concluded that my first guess was the correct one: I had left the hood open a little bit to make room for the alligator clips on the trickle charger, and with the hole in the ECU box lid, water got into the ECU and partly fried it. If I had not had the experience with the chipped ECU for Hapy when the computer semi-worked, I would not have been so quick to accept this. The Check Engine Light lit, so the A4 chat-boards all assume that means the ECU is fine. NOT TRUE. It could be partly damaged, like Nemo's.

The climate control is still in pieces, the lower dash panel is off, and the radio wiring, well, it's the same as it was: a mess. While I can move Nemo out of the way so Oliver can go for a spin, Nemo is not ready for driving around just yet. The re-assembly will wait, and I'll probably post on at least the re-wiring of the stereo plugs that the idiots at CarToys cut apart. I did, however, install the ECU box lid, complete with threading in the screws to hold it tightly shut. No more water getting in there.

Thanks, as always, for following along-

Chasing the Hapy Electrical Gremlins (part 2)

Today continues where I left off with Hapy. Last, I had pulled a cable from the rear to the front, through small openings in the frame. I wired up the accelerator pedal plug into the new cable, as well as the ignition switch. Today, we take the next few steps.

Looking Up at 40F (4C)

Yes, it is still cold. It is December, after all. Now that Thanksgiving is behind us, the holiday music can come out in full force. Meanwhile, I'm dreaming of a not-rat's-nest wiring set up. Though, I suppose, a white Christmas would be pretty great too. We start with getting the wiring up front completely tidied up. I wrapped the exposed wires from the cable with 1/2" plastic wire wrap so it remains one cable almost all the way to the ignition switch. I split off the 6 wires for the accelerator pedal from the main bundle in front of the hand brake (front is front), and wrapped that in another plastic wrap. I ran that bundle behind the accelerator pedal support down to the pedal assembly. I then fed the excess cable down through the floor, leaving a little slack in the cable, but only just a little. The work in the cab is basically done for now.

Underneath

At this point, I slid under the front end and started sending cable back towards the rear. I was only able to get about midway before the original wire clump started to become a problem. See, I reused many of the same pass-throughs that I had used 10 years ago, and pushing the cable back against these wires was really not happening. So, recognizing that the old wires are no longer needed, I removed them. Unfortunately, they were taped to the 4-wire bundle for the brake switch, so I needed to remove that bundle as well. I wasn't using that circuit anyway: it only serves to notify the ECU that the brake has been pressed so turn off cruise control. I am obviously not using cruise control, so all of those wires go. I cleared wires all the way back to the spare-tire well, and confirmed the wire colors on the accelerator pedal circuit: they match. So, while the plug changed after the 1998 New Beetle TDI implementation, the wire colors didn't. Neat.

Lower Rat Nest Tear Down

Original outlet flange

Way back when I first did the swap, I had a Vanagon rear seat heater sitting on the accessory battery tray. That heater blocked from view how bad the wiring snarl was un the engine bay. Once the heater was removed this past Summer, it could have been obvious... if I'd looked. I did at this point in this rewire, and chose to start the cleanup right there. Hidden behind the heater were the relays and other associated wiring for the coolant glow plugs. For those not in-the-know, the manual transmission TDI's delivered with an aluminum coolant outlet flange. That flange had 3 glow plugs to warm the coolant. This flange was on this engine, but the coolant outlet sticks out the wrong side. In the bus, it sticks into the fuel tank. So, I swapped it out for the plastic coolant outlet flange that routes to the sides. Anyway, all that extra wiring and relay box were just sitting there. Were. They have been removed now. I moved a couple of ground wires that were in the middle of everything and then took all of the other wiring and pushed it up through the hole into the spare tire well. The cables that remain in the engine compartment are mostly against the compartment ceiling now. I didn't do much more, because I want the wiring up above to dictate how much more I do.

Research Again

It has been 10 years since I really looked at this wiring. Fortunately, TheSamba contributor AndyBees sent me a tome of wiring knowledge back then, and since I did not meaningfully stray from his work it will very much help me now. I barely scratched the surface of this documentation when I first did this install, though I did keep it in a 3-ring binder, with the other bus books in Hapy. 10 years ago, my goal was to just get it working and then I planned to circle-back and improve / clean it up. Well, after years of wrestling with the coolant (first leaks, then overheating) and then needing a break from the bus (hence, Oliver, the 1978 MGB), I'm only now getting to this. Based on a few hours of study, I expect I will be able to significantly reduce the remaining wiring. For example, I still have relays and wiring related to the radiator fan controls, even though I have those fans on a dashboard switch. And, of course, I will not be doing cruise control. There will be other discoveries as I go.

This is as far as I've gotten. My next steps are to start eliminating wiring related to functionality I am not going to retain (cruise control, etc). Since Hapy is outside/carported, this may take a while as I wait for nicer (read: warmer) days. We usually get a 50F/10C-degree day here and there. Since Hapy is blocking the garage bay where Oliver is parked, I may get my wrenching fix with some little projects on him when the weather is too cold to play with Hapy. Time, or more like weather, will tell. Thanks, as always for following along. Please stay isolated, and wear your mask / wash your hands when you can't.

Decoding Hapy M-codes

I miss my bus. No, I mean, he is still parked out front, but he hasn't really seen much street since the Summer of 2018. Figure, with CoViD-19, all of our Summer plans were thrown out. We tried to plan a quick overnight vagabond, but even that was fraught with CoViD-fear. I routed that frustration energy into all kinds of project last winter / spring / summer, ranging from a parking furnace to a defroster. Now that the weather has turned, and our corral has thinned, he will be getting pressed into service when I need to get somewhere.... until I replace the rear bearings on Nemo, the 1997 Audi A4. So, while I set up projects for the winter, I thought I would post my M-codes, and what they mean. All of this was from my notes from 2004, but I since validated all of it here on type2.com.

Camper Designation

The first code after the VIN is for the poptop. My code is 518 which is for the Westy. I have read that 517 is for a true campmobile and 609 is for the campmobile deluxe.

Color Codes

Below the camper are the color codes. My line starts with "99 26" which indicates L90D or "Pastel White" exterior color. It is followed by "51" for dark beige leatherette interior.

Options

Hapy awaits the road

On the same line as the color codes, my option codes start with "A02". That is for a group code or a group of options that were applied as part of a package. This package included mostly basic stuff: 020: Speedometer & odometer in Miles, 026: Activated Charcoal canister, 089: Laminated Windshield, 102: Rear window heating, 206: Anti-glare Rear View Mirror, 506: Dual circuit Brakes, 511: Padded Dashboard, 524: US / Canada spec Sealed beam headlights, Red Tail lights, Side marker lights & Backup lights, 525: US / Canada spec seat belts.

After "A02", I have code "P31" which means Westfalia SO 70/2 interior. Then I have "172" which means radial (steel belted) tires followed by "507" for vent-wing windows in the front doors.

During my research I found that there were "bad weather packages" that included intermittent wipers and front/rear fog lights. Sure would be cool to find one of those.

Manufacture Date

The next line starts with the week number and day-of-week that the bus was assembled. Since it is a 1972 model year, it was constructed either in late 1971 or early 1972. Since the week number is high (36), we can conclude it was a week in 1971. Since the first few days of 1971 are mid-week, so they are shared with 1970, the actual manufacture date gets a little blurry. I have assumed that any day in the year that appears in a week marks that week as week 1. Accepting that assumption, week 36 is Monday 31-August thru Sunday 5-September. That's how the ISO defines a week. I do not know if the Germans used "0" to reflect the first day of the week or "1". Computer geeks start with 0, but I think in 1971, they probably started with 1. So, the 4th day of that week would be September 3rd. The guy who built the type2.com page confirmed that single number was for the day of the week where 1=Monday. I cross-checked by week math against the famous RAtwell, and his week math is the same as mine, so I think Hapy was born on 3-Sep-1971.

If we take the ISO rules for a week then week 1 is the first full week of the year. So, week 36 is the week of September 6-12 of 1971. The 4th day of that week would be September 9th. So confusing. For years, I thought his birthday was September 3rd, and it wasn't until I went to validate that for this post (So I didn't get it wrong) did I consider the blurriness of week 1. I intend to celebrate Hapy's 50th birthday on September 3rd AND September 9th so we definitely get it. September 3rd will be the Friday before Labor Day in the US and September 9th will be the Thursday before ChinookFest (if they hold it). So, either way, there's a ready-made party for his birthday.

Mysteries

After the manufacture week and day, there is a 4-digit code "7628" that I have been unable to identify. Based on some web-wandering it may have to do with production planning. Then, it has "UJ" which should correlate to a shipping destination. The "U" means US, but the "J" is a bit unclear.

Next, I have "2319" which indicates that this is a (2) type2, (3) Kombi, (1) that's left hand drive, with a sliding door on the right and (9) a camper. The last 2 numbers I have translate to engine (4) and transmission (1 - manual). I have not had much luck decoding the engine code of "4", but I'm running a TDI now, so it doesn't apply anyway.

Car Ports and Car Noises

What a difference a week makes. In my last post, I mentioned that I had helped T moved some stuff out of the one garage bay. Since then, K got the rest of his stuff, so Oliver is back in the garage. Also, the 2 carports from Harbor Freight arrived. So, I quickly moved from all cars out in the open and no sheltered space to work to 3 cars under some kind of roof, creating all kinds of work space. So, today's brief post if about getting the car ports up, and some diagnosis into the noises coming from Nemo.

Car Port Assembly x2

400 sqft of not raining

I have a small 2-car garage. I underscore small because Oliver (1978 MGB) barely fits between the garage door and the walkway along the opposite wall. Considering the MGB is one of the shortest cars out there, I couldn't imagine parking a Caddy or one of those big pickup trucks. Simply put, it wouldn't fit. So, when I think about how I'm going to complete Zed (1979 280XZ) this winter, I shudder. It's way too small to shoot paint, and with the gas furnace in there, I couldn't paint while heating the house, so the plan unravels fairly quickly. So, I got a couple of those 10' x 20' car ports that Harbor Freight sells (~$120US each). My driveway has a slight tilt towards the garage, but it's otherwise fairly flat.

V between

While I would have preferred a purchase ship-to-store option, the harbor freight website doesn't offer that. Instead, they offer $7US to ship it by FedEx Ground. That sounds like a cost-loss on their part, especially for a pair of these car ports, but they arrived before the primer from Eastwood (which still hasn't arrived). The assembly is actually very easy. The instructions have only a handful of steps and the exploded drawing is not as bizarre as IKEA furniture. I used a rubber mallet to get the pipes to fit together quickly. I was able to get each one assembled in about 2 hours, measured from when I walked out my garage door with a full box to walking back in after set-up and recycling/throwing away the packaging.

I set one over the top of Zed, and the other right next to it. I would rather not have a 20' dripped seam between them, and pushed the posts right next to one another. I took the 8-inch-or-so hangdown from one, and flipped it up over the top of the neighboring car port. The other hangdown, I pulled across and clipped to the tie-down seam, which runs along the inside, above the bottom rail. Then, I forced the pipes together and cable-tied them. This created a small V shape of car port tarp between the rails, running all the way front-to-back. My plan is that this will direct the water down to the lower end of the carport. I think this will work except for those super-heavy rain events we get sometimes. We'll see.

A4 Front Clunk

top of front strut, example

Now for some car content. After getting all the little things fixed on Nemo, I took him for a short test drive to see how he felt. He felt pretty good. Lots of boost, and plenty of power, but he made lots of noise. I could hear a clunk pretty much on every little bump. I figured it was the sway-bar bushings and replaced them: 13mm bolts hold the clamps on, and the bushing has a slit in it so you just need to remove the clamps, pull off the old bushing, slap on the new one and put the clamp back on. Times 2. The noise got a little better, but after pushing the fenders up and down, I believe the problem is in the strut-mount. From what I've read, after market struts that lower the front end (like Nemo has) put more pressure on the strut-mounts than the stock ones do, transferring some of the burden from the springs to the mounts to hold the front end up. This causes them to wear prematurely. So, I will be looking to replace those. Since I have a very healthy fear of strut springs, I will probably remove the struts and have new mounts installed by one of the shops around here. Better to pay with some hard earned cash than with some body damage.

A4 Rear Hum

Also on that test drive, I noticed that the rear end would make a humming noise once I got above about 30mph. I figured it was the wheel bearings, so I put the back end up on jackstands to confirm. The wheels had no play in them. None. Curious, I pulled it out of gear and spun the wheels, listening for noises (that would translate into a hum at speed). I heard clicking coming from the inner CV joints. So, that means at least removing one or both rear axles. Fun. Of course, with the AWD, I can't be 100% sure the bearings aren't bad. I may not have gotten the wheels spinning fast enough to make noise.

the diff oil fill, example

I intended to drain and fill the rear diff while the rear end was up in the air, but the fill plug is stripped. While I was under there, I got to see just how much caked on grease could remain attached to the outside of a differential without falling off. The answer: a LOT. I am really concerned about the health of this diff, and the whole rear-end, for that matter. Before I go any further with it, I will collect a second opinion. After that, I think it will have it's ass-end in the air for a while as I replace CV joints, and/or wheel bearings and fight off the fill plug so I can refresh the fluid. I'm not sure a 20+ year old 230k+ mile A4 is worth terribly much, but this is how we learn, and this could be a useful daily-driver for someone, maybe, eventually.

Well, that's it for today. I have not gotten back into the Zed paintwork since I put up the car ports. I really wanted to get Nemo road-able first. With the car ports up, I have more paint prep to do, and I need to figure out some sides for the car port space so I can heat and paint. Thanks, as always for following along-
