so i was cleaning my K&N and noticed there was excessive crap in the intake tube. so i removed the tube and cleaned it out. i looked into the plenum (opening the throttle plate) and saw there was a decent layer of black inside the plenum on the wall adjacent to the firewall and the wall perpendicular to the firewall. i checked inside the return hoses coming from the PCV (passenger side) and the other PCV(?) on the driver side and there is oil in the hoses. there was enough oil to drip out if i tilted the hoses. i checked the level of the oil when i changed it next and it was missing almost 2 quarts. there is just shy of 65000 miles on the car and it has serviced regularly since i owned it (29k). i am using Castrol Syntec 10W30 cuz i live in southern cali. any suggestions? thanks.
