I've a couple of them...The white one is the project car, the tan one is a spare :)




Any guesses?
I'd hazard a guess (or 3) looks like a v engine, either a v6 gasser (didn't they have a supercharged or turbo charged v6 back in the day?) Or a 6.5l turbo diesel. On the off chance you hit the lottery a duramax under the hood would be pretty cool.

New fuel filter with some diesel purge. Haven't got the P1248 in a few days. Hoping it doesn't come back. Also did the ol ventectomy thing to get a few more gallons in the tank.

TL;DR - fixed cruise control.

Parents came by for a visit over the weekend - the backup camera that was working with the previous POS Android head unit wasn't working with the slightly less POS Android head unit. The new head unit had come with a camera as part of the kit, but we figured we could just swap in the new one and everything would be good Alas....no.

The camera power supply line included with the new unit had a little white wire loop built in - head unit wouldn't see the signal. Snipped the wire - head unit sees the signal from the backup camera. So, we set to work pulling the old power supply wire and installed the new one. Did some futzing with the left rear bulb tray wiring (which also has a trailer wiring kit wired in).

Fast forward to the next day - pops sends a message that cruise control no longer works. Dammit, methinks. Must've pooched something with the wiring back there - messed up a brake light signal or something so the cruise decided to take a vacation....or something (wiring not my forté).
So, he brings the car back over - was about to dive into that rear bulb tray wiring again, but decided to plug in VCDS and check MB006 - and I see that the cruise switch on the turn signal stalk isn't even working - no change to the status in MB006 / 4.

So, figure it must be the turn signal stalk - I've had more than one of those die over the years. And luckily had a spare on in the parts bin.
Pull off the airbag, steering wheel, clockspring, and as I pull off that turn stalk, holding back the big wiring harness, the little 10-pin wiring harness that plugs in vertically....suddenly it's just hanging there. Usually that's a PITA to unseat due to the location and the tiny little release tab.

So....figure that's gotta be it and just bundle everything back quickly. Do a quick check with VCDS - yep, all the buttons change all the appropriate zeroes to ones.

The moral(s) of the story:
  • Verify before you tear into what you assume to be the issue (something something ass....you...me).
  • Correlation ≠ causation.
  • VCDS: If you own a VW, bite the bullet once and just buy one; your future self will thank you profusely tens if not hundreds of times

Going to start checking out the engine in my TDI parts car soon. It has a hole in the pan and I believe it was run for a short time without oil, so I'm thinking I'll pull the pan and check rod and main bearings, turbo, cam and lifters.
It has around 400k kilometres on it so from what I've read I should probably put new rod bearings in it while I'm there anyway.
It likely won't be much fun as I'll have to do it all in my gravel driveway... Going to be a pain keeping everything clean. 😝

GM 3.8 was supercharged. Like this one
Really only mean to show the bottom image, but I don't currently have another uploaded of the car all cleaned up.

Sat for 5yrs, bought and fixed it up. 3.8SC park avenue with 97k miles.

There are just too many to list....
Yeah. and in the most powerful trim, made a whole 260hp from that heavy 3.8L iron lump. . . . 10 less than Toyota's weakest 3.5L GR V6, LOL...

Replaced the wheel speed sensor today. Old one came out without too much of a struggle. Used a serrated ball bit on the dremel to clean up the hole, and the new one slipped right in. Reset the code with vag com, and all good to go.

Hmm no, I definitely can't see anything in there that resembles a 6.5.

@Fix_Until_Broke is that a Duramax/Allison badge I see on the front door?
Definite soot-stain on the rear quarter 😂
I was gonna say a 6.2 with turbo kit, but that didn't seem likely. With all the bazillion variations of the 6.5 and being an engine from that time period it seemed most possible. But I'm still ok with my third guess being right.

Started my sedan and was greeted with an unholy clatter. Wasn't like that last time I drove it, must have developed when my better half went to town yesterday. Sounded like something very bad had happened to the engine :(

The problem was immediately obvious after taking the cover off, soot everywhere around the #2 injector and I could feel the massive compression leak just holding my hand above it. The hold down clamp bolt was barely beyond finger right.

Fortunately I had a new sealing washer on hand and found a 17mm nut suitable for re-seating the injector so it didn't take long to fix the problem, but how does an injector that hasn't been touched in 10 years and 200k km suddenly get loose??

We have longbeaches on the wagon in summer. Nice wheels!
Saw long beaches on a wagon today and wow do they look good on there! Mine are nice from 15 feet lol. Definitely see a refinish in the future (maybe next winter) I got them for enough of a deal I’m not super worried for this year. Definitely looking forward to going to some meets this summer with the car.

Picked up some Long beaches for the Jetta. Along with some smoked side markers. I think it vastly improved the look of the car. Now to polish up those headlights.
I like the smoked side markers, I've been wanting to do that on my car for 3yrs or so now and it still hasn't happened.

Just got another Mk4. This time a beetle. Its wrecked and will be used as a donor for my sister's Jetta. But I am thinking of seeing if the body can be repaired and building a bhw/alh hybrid for it, and then a smyth conversion...
We will see.

The white tdi beetles are best! Almost kind of rare compared to the other colors. Such a good look. Where is it damaged? This side looks good. Even with the dented rocker.
What are those UFO rims??

The damage is mostly the front. It hit a tree, but doesn't appear too bad. Probably needs a radiator and condenser along with the bumper cover and all. The drivers door is also dented.
I'm pretty sure its just wheel covers. I haven't decided if I am keeping them or not.
