Weird problem with big turbo setup - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Hey all,

Will try to make this short yet provide great detail so hopefully someone know wtf is up.

I have an s13 blacktop with the enjuku T3/T4E turbo setup, ecu injectors, and all. I have had it running for like two weeks now. All of the sudden one day when I hit boost I saw a ****load of white smoke behind me just when I am in boost. I pulled over and saw that the little air filter that came with the enjuku kit to go on the "T" on the hot side of the valve cover had ripped and was spitting oil out and burning on the exhaust side of the turbo and the outlet to the downp[ipe, thus the white smoke. So I switched to a new one and it does the same thing! What would make oil come up the hose where the stock oil catch can thingie was. Now I just have a hose from the "T" to the OEM spot where the can was and it has always been fine until now. You can get out and rev the engine via the throttle cable and watch the oil bubble out of the air filter. There was never much oil that ever ran throught there before! The car seems to run fine still. At first I thought I blew a head gasket but there is no coolant in the oil or vice versa. Once again the oil only pumps out and burns at highy rpms. I can't figure this out. Please help. Car was so much fun and I want to get it back on the road! Any thoughts or suggestions from the more experienced would be great.

Update!--------------------------------------------------------
I thought it was the PCV valve stuck shut but the pcv valve is fine. Any other suggestions?

Do a leakdown test on your motor. You're pressurizing the valvecover, and forcing oil out through the PCV valve. It's not a problem with their kit.. it's a problem with your motor. Figure out if all the vacuum lines are hooked up correctly.. and why you're making pressure in your cover.
