that is most likey blow-by.... Are you still using the factory Oil Sperator located near the firewall bolted on to the head? if not you need a oil catch can to let it breath but also catch any oil from coming out

yea he's using the stock separator ... his setup is just like mine and mine is doing fine that is why it's stumping me

his PCV system may be failing? have him pull the PCV hose and see if it has a vaccuum sucking into it (the valve that is)

yes, a new PCV vlave is a $5 medician for a headach

this is totally normal, especially under heavy load and high boost situations. crank case ventilation.
