It had to happen sooner or later...
This past weekend my 1998 NB TDI suffered a Turbo Meltdown exactly the same way that Mickey's evil beetle crapped out http://forums.tdiclub.com/cgi-bin/ultimatebb.cgi?ubb=get_topic&f=27&t=000009
The symptoms and conditions were the following: Full power upshift from first to second, followed by the engine "coughing" and a severe loss of power. I managed to limp it along for about 100 yards or so and then it stalled when I pulled over and let it idle.
I tried to restart it and it wouldn't turn over. If I'm correct, then it is hydrolocked.
Today I put it up on stands and removed the intake manifold, turbo and intercooler.
There were about two litres of oil in the intercooler, so it's just about certain that the engine is hydrolocked.
The turbine wheel looks intact and spins freely, but the compressor wheel is siezed to the housing and the compressor wheel nut came off. I retrieved it right in the air intake to the turbo. So if the turbine wheel spins but the compressor wheel doesn't, that tells me the turbo shaft is broken, right? We'll see.
(VW dealer wants $1493 (cdn$) for a new turbo and $1161 (cdn$) for a rebuilt one.)
Question 1: Do you think that the head gasket is intact after hydrolocking? I have not pulled the head off, and I'm reluctant to do so. I can evacuate the oil from the cylinders by removing the injectors and sucking the oil out with a vacuum pump. Any ideas?
Question 2: Anyone know a good turbo repair shop with the appropriate parts to fix a busted VNT-15???
arrgh!
