Hapy not Spittin Fuel

I managed to get Hapy, the 1972 TDI-powered microbus, over to Justin to get the injection pump re-sealed this weekend. Today's post covers that adventure as well as a quick trip thru a K'Lack (2004 VW Jetta Wagon) issue.

 

Getting There

head seal complete

It has been 2 years since Hapy really went much of anywhere. Most of that time, he sat waiting for attention either in an unknown, but unstartable state or in pieces. Once I had him re-assembled with a new flywheel/ring gear and had a test drive, the original reason for him to have starting problems re-appeared: Injection Pump losing prime. I was able to prime the pump with a MityVac and then crack the injectors to get him running. And, in that way I took him on a short test drive, found some issues with the lights, etc. There remained many other issues, but at least I could get him running, stopping and had my lights so I could drive him an hour and 20 minutes to Justin's shop.

 

The night before our start-of-day appointment, I got Hapy out of the back and filled with B-20 biodiesel ($6.40/gal. same as dinoDiesel. Thanks, Trump). That morning, I filled up with coffee and hit the road. Most of the drive from West Beaverton to Justin's shop is on back country roads with few other drivers on an early Saturday morning and even fewer traffic lights. It was in the 50's (F low-teens C) and clear, making the drive very pleasant. At some point after I fixed the rear speakers, the stereo lost access to 12V so I drove in silence, a familiar scene for Hapy. The road was so easy, the thermostat never opened. I had the cabin heat on, so I may have been pulling just enough heat off the engine to keep the thermostat closed. Based on the UltraGauge, the engine temp was hovering around 180*F so running "cold". When I pulled into town off the country roads, I had a few cases of not finding 2nd gear. I noted that for followup later. When I arrived, Justin and I hung out for a bit before getting started. He has so many interesting projects all going at once, you have to absorb it all. I mean, who puts a TDI in an Audi TT while also putting one into a Rabbit pickup? Love that! The way he scraps discards and re-uses them for the basis of tools is pretty awesome too. He's even teaching himself TIG welding. Small crush, maybe. Okay, fine. He does do some impressive stuff.

 

Injection Pump (IP) Reseal

hammer mod perfecting IQ

Justin had encouraged me to get the seal kit from Cascade German, since they are local-to-Oregon, when we first set the apointment. I had already purchased the deluxe kit from DieselGeek. I didn't understand the difference. These 2 kits definitely vary in their intended purpose, so they have some meaningful differences. The Cascade German version is actually less expensive, but it includes all of the little seals usually replaced when a legit shop does the re-seal. The DieselGeek kit has far fewer seals (just the 2 on top and the head-to-base seal) and it is designed for the home-mechanic to re-seal the pump in their garage without removing the pump from the vehicle. The DieselGeek deluxe kit is more expensive because it includes specialty bits a car owner probably does not have, but are needed for the job. This differentiation is important and your case may lead you to the larger kit even if you do not intend to replace much more than the 3 included in the DieselGeek deluxe.

 

Once Justin discovered the gap, we made-do with the smaller kit. Justin replaced the top 2 seals first and then moved onto the head-to-base seal. Rather than use the included "retraction limiting bolt" and try to fit the new head seal over the top of it, the head was removed, and I held the guts of the pump in-place while Justin cleaned all the surfaces and installed the new seal onto the head. Once installed, he hooked up the VagCom and hammer-mod'd (link to Hammer Mod thread on TDIClub) the injection quantity (IQ). Justin was aiming for 6.0 mg/stk because the engine was cold (54*C).

 

The engine bay was pretty dirty, so lots of time was spent getting the IP clean before we began as well as afterwards when the whole engine got a cleaning. After it dried off a bit, we let the engine idle and we looked for leaks. None found. Justin did ask about how the starter was mating to the flywheel. It does sound loud, like it may not be meshing quite right. I'll need to remove and reinstall the starter and the starter adapter to see if I can get things to sit right. The original adapter and starter that I put in just worked for years. I would expect the new-also-stock starter would fit the same. Since this is a new adapter, that is actually designed for the application, versus one I dremel'd to fit, I would think it would fit better. It's a puzzler, but one I will consider carefully as I remove/reinstall (R&R) the starter to get it to hit the ring gear more cleanly.

 

Getting Home

If there is anything we have learned over the years about Hapy, its that he loves going places and really does not like going home. How many times have I left home and the road trip to 4 Peaks or some camping spot went great and the drive home was either very challenging or partially performed by a flatbed? Too many. This trip was no different. At first, Hapy ran great. The engine was responsive and stayed cool. Somewhere around McMinnville a charged air pipe popped off, leaving me running naturally aspirated the rest of the drive home. This served as yet another reminder to never leave home with Hapy without some tools. While the turbo is great for the overall power-band, its absence is really noticeable when trying to leave the line and get up to traffic speed. Now that it was about noon on an absolutely stunner of a day, the roads were busy where they had been empty a few hours before.

 

By the time I was approaching the Dundee Bypass, I was having increasing difficulty finding 1st and 2nd gear. Sometimes, one or the other would be right there. Other times, it was a "can't find it, grind it" experience. This persisted all the way home, forcing me to sometimes leave a stop line in 3rd. When you add in the no-turbo, I had some dissatisfied fellow travelers around me. I did get home, however, and I drove Hapy all the way into the shop so I can chase these issues.

K'Lack

After having something to eat, I switched over to K'Lack, the 2004 TDI Jetta Wagon with a BEW motor. It had been throwing a crank position sensor error, lighting up the check engine light (CEL), preventing it from passing smog. I had ordered a replacement from Cascade on Thursday, and it was in the morning mail on Saturday when I got home from Justin's. The removal/replacement of these is not complicated (remove bolt, unplug from harness, install is reverse), but getting to the sensor and the weird bolt head complicate things. The sensor sits right behind the oil filter on the front, when the engine installed transverse like normal. The bolt head is a 9mm 12-point. Half of my sockets are 6-point and the other half are 12's, designed, I think, for easier application onto hex bolts. In this weird case, that socket set perfectly onto the 12-point bolt head. With the right socket, short extension and ratchet the bolt comes out fairly easily. The plug end is fitted into a metal tang, but otherwise once unplugged, the whole thing can just get dropped through the gaps onto the ground.

 

To install, I plugged it in first and then covered the sensor with a rubber glove to lower it past the engine ick and then below the car. Could I have cleaned the engine bay before starting? Yes. But then I would have been lying in mud since the car was on my front lawn, not back in the shop and I didn't want to lay in a puddle. At this point, I found having another person to be your eyes is very helpful. I got under the car, un-gloved and suspended sensor in hand and had Boo tell me east-west, up down until I was able to send the sensor into the hole. By doing it in this order, the sensor wanted to be oriented such that the bolt holes lined up naturally. I sent the bolt thru, tightened with the socket/ratchet combo and I was done. Since I cleared the code we need to run a few cycles until it is ready to smog.

 

For the legal-minded, Oregon cops are interested in registration violations after years of looking the other way post-CoViD. K'Lack got a registration-violation ticket while legally parked in downtown Portland. Drivers beware.

 

Hapy Wrenching

Feeling confident, I switched back to Hapy, and re-connected the charged air hose. As I suspected, it was one of the rubber-to-metal bits. I cleaned both the outside of the metal pipe and the inside of the rubber with brake cleaner so they were more apt to stay together and then tightened the clamp down.

 

I next wanted to chase why the lower gears were sporadically missing. I checked the front of the transaxle to see if it was out of position at all. Nope. Right before Boo and I bought this house, I bought a Gene Berg shifter. The new-at-that-time seats were higher than stock, moving the approximately-stock-length Scat gear shift further away. The Gene Berg shifter is a few inches longer, so I figured there would be less leaning. I had not gotten to installing it before the house was bought and life took a turn. Anyway, at this point I looked at the Scat shifter I had installed, probably over 15 years ago and slid the vinyl boot up the shifter. The plastic bits on either side of the shifter appeared to be allowing more play than I remembered. Hmm. Then, I looked at the rest of that mechanism. It was very rusty, especially the foot that rests on the floor. I shot the bolts with Kroil and after waiting a couple of minutes, removed them with a 13mm spanner/socket combination.

 

rust under shifter

The floor under the shifter had meaningful rust to match the rust on the shifter foot. I don't know how much play was created by the plastic bits, nor how much may have been introduced by the rust. I do recall, however, that the Scat shifter instructions did not account for adjusting the placement of the shifter front/back nor left/right. When looking at the foot profile, it looks very much like it is designed to sit squarely in the oval without any adjustment at all. I don't know if this was a terribly good design, but I will be installing the Gene Berg shifter which does allow for adjusting. I cleaned up the rust dust, shot the floor and the shift-rod end with brake cleaner and got everything as clean as I could. Then, I painted the area with Eastwood's Rust Encapsulater (the new stuff is even better than the original) and called it a day. I still need to treat from below. I shot the picture on the right here as I was almost done applying the paint.

 

Wrap

Well, that's where we stand right now. I have been in and out of the shop a few times since Saturday and there is not a single drop of fuel on the floor under Hapy. So, we can close the book on the IP leak. I intend to complete the shifter swap and then R&R the starter next. I hope that will be the end of both issues, but I suspect there will be more to do than that. Then, of course, there are all the other things like a fuel level gauge, the radio, and the diesel heater just off the top of my head. There are many incomplete items on Hapy. Now that I have a mostly-inside (one doorway remains), concrete floor'd space to work, my desire to work on these cars has really kicked into a new level.

 

Thanks, as always, for following along and more next time-

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-

MGB Interior Panels - Part 2

Today, I continue on Oliver's (the MGB) interior because the weather remained a preventative from getting to the cars outside. Darn, have to work in the semi-heated garage.

High-Level Door Card

black door now out of place

By now, the door cards were looking completely out of place, as the only remaining all-black panels. These are a little more complicated than the front kick and rear quarter panels. First, there is a top padded section which holds the top of the door card in place. The padded section is held on by 4 screws (2 each front and rear) and is wrapped with black vinyl. The interior kit delivers with a section of cream-colored vinyl to replace it. Additionally complicating things, there are the window crank, and the door latch pull and lock. In my case, I removed the armrests shortly after buying Oliver, but there is the old blown speaker. Last, each door card is held to the door with 13 plastic clips. Since these are original 1978 plastic, I suggest having replacements on hand. The interior kit did not include these, but they are, like $0.50 each or less online.

 

I didn't take a picture of the driver card before I started, so here's a picture of the passenger side, from the open driver door. I leave that towel on the driver seat so I don't accidentally get grease or anything on there while I work on him. You may also notice I have omitted the center console. I think the interior looks less complicated this way and the console acts like a little wall between the driver and passenger, which neither Boo nor I liked. Either way, there's no place to put a beverage. I may solve for that one day.

 

Padded Section Reuse

after polishing

I considered re-covering the padded section along the top, but after removing it (4 Phillips screws), I decided not to. First, the wood inside the padding is starting to fail (see picture below). It's not totally bad, but bad enough to warrant replacing eventually. I figured that if I used the cream on that now, I would not have it when I replaced the wood. Second, the black vinyl, while also not perfect, could get cleaned up with some leather cleaner. Last, I already had a cream and black contracting interior so retaining the black long the top would help underscore that. Ultimately, I believe retaining the black just for that contrast reason was plenty of justification. I think it looks really good.

So, I cleaned the rust off the chrome ends with some Goof-Off, and polished the vinyl with leather cleaner. The window felt was fairly worm out, so I removed it with a slotted screw-driver. Rather than use a staple gun to install the new one, I used 5/8 inch #18 brads. When installing these, you will notice that the chrome/felt does not go all the way from the front rubber seal (sealing the flip-out window) to the rear-most point on the window. I taped the felt to the padded section with painter tape and held the unit against the door, shifting the felt side to side until it was where I liked it. Then, I sent half a dozen brads in to hold it firm.

 

Removing Rusted On Window Crank

backside of padded section

As easy as it was to remove the padded section, removing the window crank was the opposite. The Phillips head screw had fully rusted to the mechanism. I applied Kroil and let it set, but it couldn't effectively penetrate past the window crank. I had to resort to my set of "easy out's". I find these are neither easy, nor do they really get the stuck bolt out (could be user-error), but in this case they did what I needed. After stepping up the drill bit size a few times, the head of the bolt fell off and the window crank handle could be removed. Once out of the way, I just needed to pull the plastic retainers from around the door handle and the door card came right off. I removed the remainder of the bolt from the window crank with a big set of lock-pliers. While I had the Kroil in-hand, I lubricated the various moving parts of the window: the window control joints and the spring. Surprisingly, this reduced some of the clank-clank-clank noise when the window is raised and lowered.

 

Outer Scraper

torn down

The last bit of demo was removing the old outer scraper. This is that supposed-to-be pliable rubber that presses against the outside of your window, stripping off water, mist or fog when you roll down the window. More importantly, it reduces rain water from running to trickling into your door. My scrapers were hard and chipped, so they needed replacing. They are held to the inside of the door with 7 rivets. I set a slotted screw-driver blade against the rivet and smacked the handle with a hammer. The rivets pop right off, but the bits fall inside your door. Once free, the new scraper lines right up with the original holes, though on the very end there are a few different mounting holes, probably for use on different models. I needed to open the holes a little bit with a rat-tail file in order for the new rivet to easily fit through.

To mount, I set all of the rivets through the scraper and loosely set them into the holes in the door. With my riveter, I started on the ends, working my way towards the center. With each rivet, I would make sure that the rubber set up on top of the door, and did not disappear underneath / inside. I found that I had to press the riveter and the scraper hard against the door when pulling the trigger. With the scraper riveted in place, I checked the window action.

 

Noise Muffler

window crank and spring

With the scraper in, I cleaned up the inside of the door first with the shop-vac and then with spray cleaner. With the door cavity relatively clean, I applied some noise deadener. I realize this is a convertible, so there will always be noise. The door application is really about making the door sound solid when it closes rather than tiny and clanky. It doesn't take much to make a difference. I have read that as little as 50% steel coverage is sufficient. I am not sure I even got that much covered, though the door has a satisfying, solid "chunk" when it closes now. I ran a 4-inch tall strip from the outer rear view mirror to the door handle above the belt line (inside the door cavity, of course, but against the outer skin). Below, there are 2 front-to-back channels to which I applied 1-inch strips from the window regulator to the rear edge of the window. Below the channels, I applied a rectangle along the lower rear section. I found that the spring clank-clank-clank could be felt most on the steel directly beneath it on the inner skin, so I put a 4-inch square inside the door cavity on that section of steel. All sections were pressed down with the little roller application tool for a solid bond.

 

Plastic Sheeting

Originally, these doors had a vapor barrier. This door, however, did not, except for the small sections around the door handle and window crank. So, I made one out of a kitchen garbage bag. If I had thicker-mil plastic, I would have used that, but these bags are hard to cut, so I don't expect this to fail. I cut the bag so I could completely cover the door, and taped it in place with painter tape. With a Sharpie, I marked where I wanted the vapor barrier and then cut along the line. Since my furnace is in my garage, my options for adhesive were limited. I would have used spray adhesive or the brush-able epoxy, but both need ventilation and are explosive hazards. So, instead, I used Elmers Wood Glue. Yes, that's right: wood glue. It took longer to dry, but it held the plastic firm during the panel install. While it dried, I cut holes for the door latch and the window crank. I have found that applying adhesive on vertical angles creates a path for water droplets to follow if/when it gets between the plastic and the steel. On other words, don't apply adhesive straight across: it will only trap moisture against the door.

I could feel the end approaching. With the holes cut in the sheet, it was time to prepare the panel with the 13 clips. The card has 13 very obvious spots for the clips. They are shaped like a classic 2-ball snowman: large circle on top of a smaller circle. The clip slips into the larger circle and is then pressed into the smaller one. I could have re-used some of the clips from the original door, but after over 40 years, I was not sure they would not break during install, or shortly thereafter. With the clips in, the hole for the window crank needs to be cut next. Similar to the rear-quarter panels, the door card shows exactly where the hole needs to be. Unlike the holes for the rear quarter panel, though, the window crank hole needs to be cut almost all the way out to the hard-board edged circle. Also, the leather/vinyl has a padded backing that needs to be cut through.

I decided to not include the arm rest / door pull and I am not putting speakers back into the doors so this one hole was the only one I needed to cut. This greatly simplifies the look of the door card (see picture below), and even with the extra bounce from the thicker card, I can pull the door firmly shut simply from pulling on the padded section. The card did arrive with indications for both the arm rest and the speaker mounting locations, though.

With the hole cut and the clips in, I was ready to press it in. I started by aligning the bottom clips with the holes along the bottom of the door. Then, I clicked in the clip nearest the rear view mirror and then worked my way around, snapping the card into place. I trimmed and cleaned up the hole for the window crank (I had cut too conservatively beforehand) and then installed the crank. I again tested the window action.

Padded Section Install

so pretty

Last, the padded top goes back on. The new cards are more stiff and thicker than the ones that were just removed. It will be some time before these new cards settle in, and the original screws for the padded section were not long enough to bridge the gap, initially. So, I found a screw in my drawers that matched the thickness of the original screws, but was about 3/4-inch long. I set it aside for a moment and attached the front-edge of the padded section with the original (smaller pair) screws. I left them plenty loose so I could adjust and then grabbed that long screw. I sent it through the lower of the 2 holes in the rear mount and tightened until I could send one of the original rear screws into the door and have it grab. I checked the alignment and then snugged that original bolt. I pulled the long screw and sent the other original rear screw in. Last, I tightened the front mount screws.

Feeling quite satisfied, I shut the door... and it bounced back open. Ah yes, the cards are thicker. I closed the door hard and it held. I figure it will take some time for the rubber in the weather-seal and the door card to come to terms with one another. To help speed that, I will leave the door shut tight. Of course, the not-dry-nor-warm weather outside will help that door stay shut for a while.

Well, that's it for today. I need to do the other door, of course, but with the passenger door so close to the shelves in the garage, it will wait. Until then, well, I'll have to find other things to fix on the fleet. Like the clutch on Gramps, the rear wheel bearings on Nemo or maybe something I haven't discovered yet. We will see. As always, thanks for following along-

surround bits

UPDATE: I did the passenger door this past weekend (5-June), following these instructions. I had 2 additional observations. First, the replacement inner door felt scraper is about 1/2" shorter than the original. The missing 1/2" on my original did not have any felt left, and it was the section closest to the door handle, up against the chrome end. Second, I omitted the last step in the instruction above regarding the 2-piece plastic rounded-cornered rectangle that goes around the inner door pull. These are thin, and could be damaged upon removal. Fortunately, my old vinyl cards were not holding on too tightly, and they removed with ease. The top part slid right off, simply by pulling up. Once removed, the bottom came out easily.

Installing the Plastic Inner Door Pull Surround

I found the install to be much more difficult. The new vinyl has much more grip than the old vinyl. Also, the card wants to be flat, so there is natural pressure away from the curvature of the door. The plastic bits had 4 little bumps (one on each short side and 2 along the longer side) that need to get under the door pull. After multiple failed attempts, I found success. Starting with the bottom piece, I got the plastic wet. I set the 2 short sides on either side, below the pull, and while pressing against the card with one hand, pressed upwards on the corresponding corner of the surround. I moved from side to side, moving it a little at a time until the bottom edge clicked in.

halfway there

The top piece was harder to manage, in part because my card has a piping strip that runs right along the spot where the plastic bit needs to sit in order to install it using the same method. So, again, I got it wet (reducing friction) and rather than start at the uppermost corner, I lowered the plastic piece so it was just below the piping, with the leading edges on either side of the surround. This placed pressure on the piece, and this is where an original piece could break. With one hand pushing the card against the door, I pressed the little bump under the inner door pull. This was a little scary, but once the second side snapped in, I followed a similar effort of sliding it down a little bit at a time on either side. Eventually, the top and bottom pieces meet, and the cards are complete.

Again, thanks for following along. I hope this last bit helps you out. I found following these instructions really helped me out when I went after the second door.
