Anyone that's boosted(or maybe some of you N/A guys) seem to have excessive amounts of oil from or related to PCV? I'm getting way more oil than I ever expected too in my charge piping pre intercooler. I was running without the PCV system hooked up for a few miles; had to take the car down to repair a coolant leak, and when I separated the lower charge tube from my intercooler I noticed a copious amount of oil in my charge piping. So I installed my PCV this time, and still continue to be getting way more oil than expected(maybe 3/8-1/2" wide stream 1/16-1/8" deep right to my first coupler from the exducer.) BRAND NEW BW turbo charger unit so shaft play/turbo failure is next to out of the question ALTHOUGH I wont rule out manufacturing defects. I could have a bad oil shield/seal on the compressor side its just extremely doubtful to me. -8 oil return to the pan so I know I'm not flooding the turbo with oil that's plenty large. Turbo has a built in oil restrictor, so once again no way I'm flooding the CHRA with too much oil to force it past the seals(at least I wouldn't think so). I'm truly at a loss here my built motor is running good the only thing coming out the exhaust is condensation and ethanol scent; no notorious "black smoke" from a bad piston ring seal or ring blow by. I think I'm going to install the PCV baffles factory from Nissan to see if that helps and maybe install my catch can too while I'm at it. I just figured I might run it by some other boosted guys being that I've never really monitored how much oil is "normal" from the PCV system I don't really know what I should be expecting! Even though this seems rather abnormal to me.
Chime in guys lemme know what you think. ![]()
