Turbo Leaking Oil

GreenChevelleSS · 10-28-2005, 02:55 AM

well i got the car with a blown head gasket and I havent heard it run yet. I got it very cheap and figured I could fix it pretty cheap and fast and use for a daily driver instead of my consistent 15mpg truck.
When I pulled off the intake tube that goes in between the intercooler and the turbo, enough oil poured out to fill a about a 4oz container and then when I set that tube to the side more oil came out of it.

May I suggest a PCV Catch can breather?

Yea i dont think this much oil could come from the pcv.

I think im gonna go ahead and pull the engine anyway to check the bearings and rings. Any tips on pulling the engine?

Ok, anyone here ever had bad rings? or massive blowby that wasnt a turbo seal? that caused that much oil in th IC?

is the turbo sloppy with endplay side to side? Was the old head gasket visably bad?

Yes it is visible. I have a picture on my website of the blown headgasket, you want to look.

Its not the rings that im gonna pull the lower end out for, its the bearings. I dont want to get it back together and have the lower end knocking or a spun rod bearing, how common is this on these lower ends?

OK back to the question, Should I rebuild my Turbo? Is there a way I can check and see if its leaking before installing it? Its a bitch to get on the engine with the engine out and even worse when its in the car. The turbo seems pretty solid but I dont want to have to pull it back out... is it hard to rebuild?
