Oil in my plenum

For some reason it's getting a little oily in there. Anyone have an idea what it could be?

Normal. Your PVC gasses are routed into the plenum, and they are usually oily.

No the other side bring in fresh air into the engine.
Do you have oil and smoke coming out the PCV side?
also check for good suction on the PCV itself.

the other line is used it replace the air that is removed from the PCV side. if you have oil on the inlet side(passenger) then you may have a blocked passage

is there alot of oil?
