Bad valve seals??????

[gmoutdoorsman]

I have oil coming into my intake manifold,i replaced the pcv valve and was thinking the only other was thing it could be is bad or worn valve seals. The truck never smokes and it was a small amount of oil.

First sign of bad valve seals is a puff of smoke when you first start it. (exhaust seals). If it's getting into your intake, I would suspect the intake gaskets.
