pcv system or piston rings,valve seals..has to be one of these or all of them..lol

im gunna say valve seals on this one.
your better off just replacing the valve seals and head gasket.
make sure you dont have coolant and oil mixing.
if you have good compression id assume piston rings last.

check your pcv valve/system. Thats my guess.
