00 Civic Coupe
Hey guys, I'm having an issue with oil from the turbo getting into my intake. I've had the turbo checked by Garrett, and they say that it's in good shape. I have done several things to try and remedy the possible crankcase pressure issue. I replaced the valve seals, and the block is vented properly. The engine does have piston slap and I think that is causing the case pressure which is causing my oil drain to back up. I just wanted to get a few opinions on the issue before pull the engine and build my other block with a tighter P2W clearance.
