I just got the car back somewhat driveable last week, car had new 99 turbo's installed in it a week before it was crashed (rear end). finally boosted on it and it looked like the damn car was on fire. only running 13psi on it at the moment. Turbo's were fine, could they be f;d from sitting for 6 months? there was some oil in the intercooler from the previous set that blew, think that could have been blown into the motor? (FMIC kit).

 

make sure your crankcase is ventilated properly via the nipples on the oil filler neck

 

my FD would smoke bad and it would fill the damn block up with smoke.i took my turbos apart and found my primary leaking.i would say your problem is the turbos.if i where you i would take the turbos out and inspect them,its a pain in the *** but is not that bad,i did it in one full day.

 

I'll check the vent first, my friends been working on the car for a few weeks doing body work and cleaning up thing under the hood, I wouldn't be surprised if he capped that line off.
If not, I have a T76 that was going to go into the car at the end of the summer, might as well do it now if the turbo's are bad.
