I actually did something with this car this weekend. The motor has been using oil badly at idle and after decel since last winter when I beat it hard over the mountain in a ridiculous blizzard. I did not think it was the turbo. The engine ran great, had perfect compression and always started, so I was a bit confused. It did not use any oil when actually driving down the road, but would load up when sitting.

I mothballed it and drove it every couple weeks to keep things lubed up.

Pulled the motor saturday and tore it down. Nothing obviously bad, but several of the valve seals were dumping oil past valves. Turbo is dry and tight. The valve seals surely look like the source of the oil. I'm not sure why, but I did mess around with this head a lot with grinding valve faces, self porting ETC. The valve guides had similar wear to what they did the last time I checked it, so I dont know what changed.

I pulled the pistons, and everything looks great in the bottom end. Ring gaps were perfect. The oil control rings were pretty much plugged with soot, I assume this is from its veggie days.

The plan is to clean up the rings, replace rod bearings, and put a good, unmolested, low mile head on it.

I still need to measure the bores, but they looks really good to the naked eye.

just randomly decided to check local craigslist for parts. There was a mk3 tdi jetta running well with 149k miles for $200 in my town. I called up the local tow dude, told him to head over there and give the dude $200 and bring it to my house. Should have another shitbox in the driveway when I get home. People want like $300 for used heads.

Yes, I'll take a whole running car for $200 Alex.

I'll probably be selling the 90 when I get it all back into good health. Too many other things going on. Bought a clean 96 tacoma in Reno Nevada. Going to put the ALH from my jetta in that. The jetta is getting too rusty to inspect next year.

No shortage of shit to do around here.

...but in Seattle the windshield would probably not be the only thing holding the roof on because all the pillars are literally not existing anymore.

That being said, you can get an inspected and decent looking mk4 TDI jetta here for $1000-$1500. Rusty non inspectable ones are 200-500. Makes me want to hord them all.

The few remaining mk3 cars around here look like they have been pressure washed with hydrochloric acid for the last 25 years.
