I have an 04 Sti w/ 85k on it stock beside an intake and blow off, and i loose oil and I find some of it in my hoses and intercooler tubes. I put head gaskets on the car at 65k. It has been doing this for a while, and it starts and runs great, my plugs are dry and the exh housing on the turbo is dry. It doesn't smoke. I figure if the turbo is bad I would have more symptoms. Dealer says there is no pcv valve. Just wondering if anyone has had this problem or knows how to fix it.
