On accessories

My aftermarket jail bars came in. Now the spare tire won’t tap on the window, and my feet won’t kick the rear window when sleeping anymore.

On Cleaning

Went out today in my fever-dream haze and decided to get some fresh air by cleaning the back patio. Spent a few hours back there, organizing tools (dumping both boxes, cleaning everything, and sorting it as it went back in), power washing, etc.

The reason I’m posting it here, though, is that I found a brand-new sliding door rubber seal for the bus! I thought that maybe I bought one back when I first bought the bus, but wasn’t sure. As they’re like $60-100, I was reluctant to possibly buy a duplicate. Now I’ve got one that’s only a little sun baked!

On second versions

Going to re-print the door handles. I just added a channel to add some 6mm round bar (bent to shape, obv) for reinforcement. Driver’s handle is cracking a bit.

Also designed a simple m14 spark plug holder. Will have to use an old spark plug to thread the hole, but holds four plugs and designed to be installed in the engine bay. Saw a vintage part up on ebay, decided it was something I could make very simply. Printing it now.

On Privacy II

Small update: for the front curtain, I’ve been using a string run between two (3d printed) utility hooks. I’ve had, on my “to do” list, “curtain bar bus” for about six months.

Today, I finally did that. It’s not fancy, but it gives a lot more privacy. Shit quality photos, because camera was sold for (vw) bus money. But they get the point across:

I also took care of putting in a new valve cover gasket on the CR-V. One of those cases where, no matter where she parks or what she was doing, it leaves a dollar-sized oil spot, but I notice no oil level drop of note between changes. Maybe from the top of the top hole on the dipstick, to the bottom of the top hole.

Probably helps that I have all of the real tension washers now. Before, I had lost maybe 2 or 3 of them, and was using standard washers.

On winter warmups.

I’ve been having a dog of a time getting a smooth idle when it’s cold out. Anything under, say, 50 degrees, and it’s a bear. Plenty of power when running, but when returning to idle, it tends to dip down, then recover. Sometimes it pulses.

I know the carburetor has issues, and I’ve got a solution for that hopefully coming in tomorrow. Still, though, I need to fix the root problem, and that’s the lack of intake preheat.

Every single website that sells carburetors and intake kits recommends that you don’t do a single center progressive on the Type 4, because there are no exhaust setups stock that offer intake preheat tubes. Some people who do center carbs try to fix this by welding their own intake exhaust preheat tubes up, or add “thermal reflectors” (aluminum sheets) over the intake pipes, so block heat is trapped. Others make pipes that go from a shroud around an exhaust header, and run it to a cardboard box built around the air cleaner, and I myself may do something like that. However, the vast majority of people simply live with it, or don’t drive in the winter.

I’m going to trial something different. I don’t know how long it’ll survive, or if it’ll even work, but for $40 it’s worth a shot.

First thing, I stripped out the old heater booster fan wires and relay. The way it worked is a switch on the front heater lever grounded pin 86 on a relay, which was powered from the alternator voltage regulator output, to prevent you from draining the battery without the engine running. This relay switched a big honkin’ fused lead straight from the battery, to the heater fan. However, being 44 years old and in an engine compartment led to these failing often.

Superior German Engineering :godwinning:

I cut the heater fan wiring loom back until I was past the crispy bits, and wired that into a stock 5-pin automotive relay. Bad pic, ignore the kapton tape (taped up a test light)

zSzMqQsl.jpg

I’ve wired this down to a set of four, 10x200mm, “7.5W” 12V heaters. Currently they only have a small bead of arctic silver [knockoff] compound in a strip on the bottom, and I’ve kapton-taped them to the intake runners.

So, with the engine running, I can pull the once-unused (used to open the flaps to the exhaust heater boxes) heater lever all the way down, and it clicks over the relay, which turns on the silicone heating strips. Before buttoning everything up, I got the engine running, and tested it. They warmed up right quick, to the point they were nearly too hot to touch. This is hopefully going to be much better than having icy-cold runners. I’ve honestly seen condensation on them after a freeway run to work. I also smeared a thin coating of copper RTV on top and in the sides of the silicone strips, to give them a little more sticktivity for the next week or so of testing. If everything works out, I’m going to wrap some insulating fiberglass/silicone tape over them, and call it good.

I’m aware the best place to put them would be on the bottom of the runners, as that is where gasoline vapor is probably condensing and running down to, but that’s a right pain in the dick with everything installed. Plus, as-is, if one burns out, I can rip it up without disassembling anything. I have no idea what kind of lifespan these little (I’m assuming) nichrome-mica heaters have.

On new stomping grounds

Pulling the old engine, and removing the tins, was the easiest part.

I tried capturing the mounds and mounds of oil crud on the intake valves, but even Lightroom can’t save this one

Mmm, so sexy.

The current wiring, while at a bare minimum of necessary wires, was quite messy.

We also wanted to do something with the engine bay. Clean up the crud and maybe cover the rusty spots.

Tins removed, and out on the rocks.

“Zundfolge 1-2-3-4.” Buddy speaks fluent German, says it’s the equivalent of “firing order”.

My buddy has this actually really good Ryobi pressure washer. It’s leaps and bounds better than the Harbor Freight “Blue” washer I have. After he accidentally hit his toe with it (and promptly sliced it right the fuck open), he switched to boots.

The Exhaust extensions I made. This was leaky as shit on the drive over, so we eventually pulled it all apart (the stainless fasteners seized solid together in one single drive, but the “Grade 8” O’reilly’s metric bolts were easily removed, hmm) and re-sealed it.

I5GjNl0h.jpg

The transmission seal is clearly leaking. It was 50/50 which one was causing the wetness at the engine/bellhousing joining point, and now we knew. I replaced the seal after washing it out.

Pressure plate. I didn’t have the funds for a new pressure plate (they’re like $150-200), but I got a new clutch, so that’s 50% of the way there. Despite the pattern, it’s fairly flat on the edge of my caliper slide.

We spent the first night (last night) fitting the painted tins. At least, when you’re an EMT, you have an infinite supply of gloves, and can change them if they ever get any grime on them. Don’t want to mark up the fresh paint!

Now, preface. Between the next two pictures, about an hour passed. The lift table was an absolute godsend compared to how we did this last time, with a jack and a piece of wood. Even with it, though, getting the engine mated up is a trial of patience. We eventually got it on by having my buddy up top holding the table, and me on the ground watching the bellhousing mating point, and giving directions. I ended up spinning the flywheel with a flathead screwdriver while he was shaking the engine side-to-side. That got it over the crankshaft splines, and it mated up.

We discovered that, if we backed the bus up to the edge of the driveway slope, it gave us a few more inches of clearance.

I found a website, germansupply, that has exhaust flanges available. I’m going to order two sets of flanges, and have a welding shop make 4 inch extensions, so I can use my current exhaust. Otherwise, I’d have to modify either the exhaust headers, or the collector/muffler. Extensions will let me us any stock off the shelf solution.

Now if only germansupply would ship the damn things!
