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-

Zed Body Kit Start

Last Summer, amid the economic restart following the CoViD-19 shutdowns, I ordered and received a fiberglass bodykit for a Datsun 280ZX. It arrived too late to be wrapped into the body work, and I ran out of warm weather anyway. Today, I restart the body work on Zed (1979 Datsun 280ZX), with hopes for having Zed painted before I run out of summer this year. Even though there is considerable Summer left, my time is less available this year than in years past. Boo has injured her arm/shoulder, preventing her from moving it per Dr orders, so I am doing a lot more not-car stuff these days (read: lawn care, housework, etc) which all take precious minutes. 

Back to Start
bumper gap set
While Zed was parked under a canopy / car port all winter, that is not the same as sitting in a climate-controlled garage. Or even an unheated garage. Rain does not fall straight down, and wind blows organic material around. So, when I was ready to focus on Zed, I had a few steps to just get him back to where I had left him last Summer. I had been using his interior as a staging area for parts and boxes while working on the sound/noise contain effort in Hapy (1972 VW camperbus). So, logically, the first thing to do was to vacate the interior and shop-vac it out.

Next, the body panels needed a cleaning. Rather than use a hose, I hand washed him with a bucket and scrubber sponge. Still, I was unable to free some of the green haze that had appeared. He would need a sanding in order for the next layer of paint to adhere anyway, so I left what remained to be addressed by the sanding. I pulled out the body kit that had been stashed inside and cleaned it too.

Front Fenders
d-side bumper
I had spent some time wrangling the front bumper last Summer. I could only get so far because I had not completely solved for the fenders yet. Now that the driver fender was ready, I could move forward. I started by simply mounting the fenders with M6 stainless bolts. When I fastened the bottoms, the fenders ballooned out into their proper shape. I had not realized how flat they had been sitting until then.

Rear Bumper
The rear bumper was the closest to being complete, and after spending so much time on just getting things back to the way I thought they were, I wanted a win. I started fiddling with it and I discovered that I had not really prepared the steel rear bumper hidden within: it had rust spots on it and it was still dirty from when I bought it. More cleaning with a bucket and a scrubber and then sanding, rust treatment and a shot of Rustoleum got it ready enough for use. No, I don't really like the idea of Rustoleum on this project anymore than I think you do, but this will protect the bumper well enough, and once I sand a key into it for the epoxy to grip into, the paint choice really won't matter much anymore. After the paint cured (or 48 hours later...), I re-attached the bumper, making sure the height was completely flat, with the same distance between the tail body panel and the top of the bumper. It is into things like this that so much time is lost. Bolting on a bumper takes, like 10 minutes. Getting it exactly height-right, took more like 30.

p-side bumper
Once the steel bumper was set, I returned the fiberglass bumper to position to get it exactly where I wanted it. After some time spent fiddling with it, I was able to set the bumper such that the gap is the same across the rear, from corner to corner, and the seams along the rear quarter panel were consistent as well. I drilled a hole inside each wheel well near the top of the bumper and set it for good with a pair of M4 bolts. With the height set, I set the spread (tilt in or tilt out of the bottom of the bumper) of the lower edge. I controlled this with a second set of holes lower in the panels. Again, I set 2 M4 bolts through the bumper into the rear wheel well. I may eliminate some of these bolts later, after the epoxy sets.

Side Skirts
setting the spread
With the rear bumper looking good, I shifted forward to the little skirtings that run under the doors. I was not 100% convinced these were necessary when I bought the kit, but now that I have them roughed in, I like them. These kits are one-size-fits-none. While that was not really true with the rear bumper, it was definitely true with these side skirts. The length is quite good, and the fit into the wheel wells was almost perfect. I say almost, because I had to cut a small chunk out of the top of the passenger side skirt for it to fit. The issue with these skirts is with the little lip that runs the length of the door jam. These are designed to sit on the outermost edge of the door threshold, but the design has 2 problems. First, the lip is fairly thick so the door does not easily close on top of it, if the door is set at the right height. Second, and perhaps more important, the lip is not at the correct angle from the outer edge of the skirting. So, if you set it in place on that outermost edge, either it is in the right spot, but completely blocks the door -or- the whole skirting curls under the car too much, not aligning with the fender lines and looking horrible. I resolved by cutting off the lip with a hacksaw. Yes, that is a rather destructive move. I considered all the plastic panels on the ToyoTruck and the panels that run under the doors do not have a lip hanging on the door sill. These will now be a same.

fun with Bondo
With the lip removed, I was better able to control the angles. Similar to how I managed the rear bumper, I first set the height by getting the under-the-door edge just a smidge below the door opening. I set the height temporarily with clamps and then bored holes, used more M4 bolts to hold the tops in place.  I added a bolt on each side, near the leading edge of the door, to hold the section of the skirting which will attach to the front fender in place. I will use this bolt for setting the epoxy, but will remove it, or cut the head off, after the epoxy sets. Next, I set the spread so the rear outer edges aligned with the rear bumper lower leading edges. Because of how the skirts were constructed, this left a small gap at the top rear of the skirt. If I pressed the top against the side of the car, the bottom of the skirt would stick out too far. The picture below shows how it lined up. Because of the curve of the body, it is not immediately visually clear that the bottoms align, but they do. 

Body Fill the Gaps
d-side skirt rear
Around the internet, Bondo is a four-letter word. No one admits to using it, but practically everyone does in some capacity. If I were a master fiberglass guy and had all the time in the world, I might have built-up the trailing edges of the side skirts with fiberglass. That would have been the "right" way to do it. I don't have that skill, nor the materials, and, like I indicated at the top, I really don't have that time. So, I chose Bondo, and went full-on ShadeTree with it.

I have the panels attached exactly where I want them, held on with bolts. I don't want to remove them apply some material grind some down, re-attach, wash-rinse-repeat, in hopes of getting it right. That could take all Summer and still might not look that great. I want to apply filler to the fiberglass but not create a Bondo-bond with the side of the car. To resolve, I grabbed some non-stick spray from my kitchen and shot the steel body panels where I needed to fill a gap. I then cleaned the fiberglass with oil/grease cleanser, leaving the non-stick on the steel and I filled the gaps with Bondo. Is this how a pro would do it? I sincerely doubt it. Did it work? It worked well enough to define the lines. Once teh Bondo set up, I freed the panels, leaving them loosely attached. There was not any Bondo stick to the steel. I sanded things smooth and did another pass to get the seams really clean. Last summer, I tried to resolve the don't-stick by taping plastic to the steel, but no matter how well I set the plastic, there were minute folds which appeared in the dried Bondo. The non-stick spray left a predictably smooth line.

Sanding
body sanding fun
I re-attached the rear bumper and the side skirts after sanding the Bondo smooth. Then, I set into sanding the entire car with 320-grit. As I mentioned above, simply cleaning the body was not enough. Besides, I chose to not sand the primer last year, believing it would better protect the paint over the winter. It needed to be sanded before the next coat, be it more primer or color. I will be priming the fiberglass body panels anyway, so I may shoot primer on the rest. I'll decide that later.

I am about 2/3 done with the sanding of the whole body (fiberglass and steel), working from the rear forward. Once the sanding is complete, I will be setting the height of the front bumper ends, and perfecting the front bumper seams like I did with the rear bumper and side skirts. After all that, the fiberglass will be removed one last time for priming.

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

Phil and Phrends Road Report

A few weeks ago, I changed tactics on the sound deadening / interior refresh so Hapy would be ready for a trip to see Phil and Friends play in Eugene. Today's post covers that trip. For my US readers, Hapy belated Independence Day.

Unrelated: Northwest String Summit is having their final festival this year. While this may not arrive as news to some, it may be to others. I failed to get tickets, and have given up looking for myself but I am hoping you might have a line on a pair for my friend and his caregiver. My old dear follow-the-Dead friend was diagnosed with MS a few years ago, and he is now mostly confined to a wheelchair. I don't know how many festivals he has left in him, so I'm using my 'Miracle ticket mojo' to help him get to one more. If you know someone who was going to go onto CashOrTrade, Craiglist or something to offload a pair of tickets and a parking pass, please consider routing him/her/them to me so I can connect them with Mayhem, the merry fester.

Terrapin
rest area
The last time Boo or I saw Phil Lesh play live was 2013. Now, nearly 9 years later, we had the opportunity to see him play with his son, Graham. Over the years, Boo and I visited Phil's now-closed venue, Terrapin Crossroads (TerrapinCrossroads.net is gone now too), but we had not been able to align a trip with a time he was on-stage. When we heard he was coming to the Pacific Northwest, I jumped on tickets, with a hope that we could catch 2 shows, knowing that he may not pass this way again. The closer venue, the Cuthbert Ampitheater in Eugene, offers reserved seats for those willing to pay a premium. Again, I figured our chances to see Phil are decreasing with each year, so I got us a pair of seats maybe 20 feet from the stage, in the center of the house. Arguably, this was the closest I've been to the stage occupied by a member of the Dead since my touring days, and it was really special to see the facial expressions and the non-verbal communication between the players.

On the Road Again
Before we could take our seats, of course, we needed to get there. Boo worked the day before, so I assembled the usual gear without her. This has become virtually automatic, since we have it fairly well organized: 3 milk crates of stuff plus the canopy, bedding stuff, a large water cooler and emergency stuff. Since I had emptied my overflowing toolbox into that new tool cabinet, I needed to assemble a smaller tool set for the road. Rather than carry everything, like I used to, I grabbed my 10mm and 13mm ratcheting spanners, a small set of sockets, a pair of stubby screw drivers and a pair of longer handled screw drivers, a couple pairs of pliers (one needle-nose, one regular) and a couple pairs of scissors (one fine, one larger shears). Last, I tossed in my multi-meter, some wire connectors and a roll of electrical tape. I figured that if something broke beyond those tools, we would flatbed home.

Boo and Hapy, pre-func
On travel day, we assembled a couple of days of clothes, a small cooler of drinks and snacks and hit the road, stopping for some B20 at the corner filling station. Reflecting the new reality, our corner station was charging more than double what we paid in 2019 ($6.05/gal versus $2.99/gal). The price has continued to climb since then, like everywhere else, it seems. The freeway leading to the interstate was very busy, and crawled slow, but it allowed Hapy time to get up to temperature and settle down. Most of the squeaks and moans that used to plague our trips were gone, leaving the low drone of the engine and a wind-whistle near my left ear, coming from the door seal.

By the time we hit I-5 South, his engine temp was steady at 185*. South of the I-205 interchange, traffic spread out a little bit, and we could just cruise. We had all day to get to the Cuthbert, so we didn't push Hapy too hard. We knew that the speedometer reads slow, believing that when it reads 60mph we are closer to 65mph. For fun, we tried to calculate exactly how fast we were actually going by taking stop-watch times between mile markers while I tried to hold speed at 60mph. Of course, holding a steady speed on uneven ground in traffic is not exact. Nor is clicking a stopwatch as you pass a mile marker. Still, we determined that when the speedometer reads around 60mph, we are actually going closer to 62mph. I guess, it's not as far off as I thought.

Wheel
Stu, Phil and Graham
Just the fact that we were talking about speed and speedometer accuracy describes the drive... by what we were NOT talking about: temperature, struggling to keep pace, electrical gremlins, thrown codes, etc. From start to finish, the engine temp peaked at 190*F and that was on the uphill south of Salem where I have seen Hapy's temp climb upwards of 200* in years part. We were able to take the hill in 4th gear, holding steady at 60mph on the speedo. So far, so good. The drive south was dry until around the Corvallis exit, when the rain started. The road remained clear, and traffic good all the way to the venue, but it was a harbinger of things to come.

Of course, we did discover or encounter or develop some things along the way. For example, when I installed the stereo head unit into the glove box, I did not include the metal cage that would have locked it into the box. Why? I wanted to easily remove the head for the inevitable installation of an amplifier. Well, without that cage, pushing buttons with more than the lightest pressure caused the head unit to slide backwards into the holder. Yep, that happened. Repeatedly. So, I will be putting in the cage, and will figure out how to manage an amplifier install which includes a removing the head unit from that cage later.

We discovered that one of the tail lights has a dim brake light. It is not out, it is just dim. Also, that weird issue where I cannot turn off the engine without my foot on the brake pedal re-appeared even after I cut off the entire diagnosis plug. Clearly, I will have to cut off that diagnosis wire from the driver side taillights. If that doesn't work, I may replace the wires from the brake switch to the taillights so any weird grounding from 50+ year old wiring goes away. This may also address the dim bulb.

Speaking of brakes, on the way home, Hapy lost his vacuum/boost brake assist. This could be something as simple as the hose nearest the booster got some brake fluid on it and compromised it to the point where it failed. Or, this could be as big a deal as the booster unit itself has failed. Since Hapy is over 50 years old, and the brake booster is original (and has a healthy coating of rust), I will be assembling parts expecting the worst.

Truckin'
Unbroken Chain
With these downsides, it would be easy to dwell in the negative. Those issues were the only ones we encountered. We used and greatly appreciated the 2-way dome light by the slider. The single position was really handy when we first got back to the bus after the show. Otherwise in the dark, we could find the camping chairs, some snacks and bev's without reaching for a light, shining a flashlight or even setting muddy-foot inside the bus. The floating speakers and the headbanger speakers were very useful for the pre-func after someone parked right next to us, preventing us from hanging out next to the slider. So, we moved to the rear of the bus, popped the rear hatch, and moved the speakers. Boom, we're wrapped in sound, comfy as can be.
 
Regarding Hapy functioning, the rear anti-sway bar had Hapy holding the road like never before. There is considerable open farmland south of Salem where there are fairly consistent, strong gusting winds. The winds are especially strong when a storm is approaching, as it was on this drive. In past years, encountering those winds has been a white-knuckling event, buffeting the bus, pushing us into either the next lane to the left or into the shoulder. Not this year. I drove in a relaxed body position, with gentle arms and shoulders, the entire drive. I felt the wind, but it didn't move us. The topper of it all, though, has to be the new front seats. Unlike prior drives, where I felt like someone had driven over me by the time we got to our destination, these Sprinter seats were so comfortable, my body felt like we had driven across town, not 2+ hours. I believe the relaxed posture and happy body were a result of the anti-sway bar, the stiffer shocks and the new seats combined.

Cold Rain and Snow
After the show, we waited for the crowd to thin before leaving the parking lot. As we started to leave, the staff pro's had assembled in a line with their flashlights to start shepherding stragglers, so our timing was spot-on. The exit routes fairly easily onto I-105 and then on to I-5 North, so we started our way north. By the time we left the lot, it was almost midnight and as the miles ticked by the show afterglow started to fade. Hapy was driving so well, though, neither he nor I wanted to stop. He definitely didn't want to. His temperature was holding at 185* no matter how fast we went. There was a point when our speedometer hit 75mph (the rpm counter near 3500) when we passed a truck and Hapy just cruised without a bump in his temperature. Eventually, I couldn't combat the fatigue. So, we hit the rest area just north of Albany to grab a nap, vagabond-style.

Once we had things set up, we intended to use the USB chargers in the headbanger. They work great, super-fast charging, but they cast a blue light that is super annoying at night. So, I will be covering the LED's with black electrical tape to dull them.

I mentioned the rain on the way South. We had intermittent sprinkles through the evening, but it was mostly clear during the show. It remained clear for our drive as far as the rest area heading north, but when we awoke the next morning, the rain had set in. It appeared to have been raining steadily overnight. It was constant, but varying in intensity from moderate to heavy. And, it was colder, like mid 40F's.
 
rare picture of me
We packed up the vagabond, returning Hapy to a drive-able state and headed back onto the interstate. It was at this point that a lack of a defroster became apparent. Of course, Hapy has never had a working defroster, like most type2 busses, but still, after driving more modern cars, it is becoming a glaring gap in the wet/misty Pacific Northwest. We wiped down the windscreen and front windows with a towel, and pressed into the rain.

I Will Take You Home
Driving Hapy has become such a pleasure, but in interstate traffic, when you can't see terribly well, in rain so heavy that the ruts are becoming hydroplaning ponds, the joy fades. Of course, the brake booster was no longer functional, so I had the need for extra stopping distance playing with my mind as well. By the time we got to Salem, we needed some breakfast to consider our options. The weather system which had settled over the northwest was still just moving in from the southwest, moving northeast, covering our entire trajectory with heavy rain. This was projected to continue all the way to Seattle, our intended next show. As much as I love Phil, and as much as I really wanted to be there, I feared I would be a mess by the time we got there. Then there would be standing/dancing in pouring rain followed by camping in pouring rain, packing up in the pouring rain, and then driving 5 hours back home in... you guessed it... pouring rain. Our best guess was that we were looking at 8-10 hours of driving. I just couldn't do it. So, for the first time since I bought Hapy 20 years ago, the humans gave up before the machine did.

After breakfast, we hit the highway and went home instead of continuing on to Seattle. In the end, this was probably the better choice for Hapy, and for us. We stopped wanting more, but perhaps more importantly, we stopped before Hapy really gave out. I have brakes to fix, a stereo to mount, a pair of USB chargers to dim and a defroster to figure out, in that order of importance.

Thank You For a Real Good Time
I didn't really mention the show, and I won't be posting independently about it. It was a lot of fun, and they played well. We hope we get to see Phil again, but if we didn't, our last time spent with him was far from Plain Jane. Quite the opposite: the jams were tasty, the arrangements purposeful and the execution spot-on. If I had any disappointment it would be the keyboardist (Steve Molitz) not being loud enough in the mix during his solos. He was rippin, but we had to strain to hear his leads over the rest of the band. Arguably, he was putting the most energy into the performance, almost like he was playing with Joe Russo.

This was a highly successful trip. While I will have some work to do before the next one, it is always easier when you are building on success rather than trying to resolve after a failure. Fair warning: the blog may go quiet for a while as I re-enter the work for Zed.
