My engine is leaking oil and I'm having trouble diagnosing the source. It seems to be spreading around the engine's lower half and somewhat evenly distributed. I'm wondering what specific gaskets you all have seen blow as a result of adding boost. By the way, I just had a compression test done and it's not the cylinder rings, and the engine runs great. I'm not losing too much oil, but it is getting worse.

 

check the oil supply/aps solenoid/blah blah area. there are several joints there that can leak oil, and it tends to run down the motor and drip from anywhere. also check the bottom banjo on the turbo, and the sump pump lines. with this turbo system there are several places for it to leak.

 

hopefully not the rear main seal, lots of labor to fix!!!..this would be at the rear of the motor (duh)...dripping out by where the tranny mates up...

 

that would suck pulling the tranny for a gasket, but APS Single turbo kits...come with "teh smoke". Propaly just gotta replace a turbo, damn whats up with the APS ST kit, always making smoke or leaking oil....
