If it isn't that, you could swap to the different valley cover.

valve seals...
what it is, is when you are at high rpms and and let off the gas there is a high amount of vacuum in the intake tract because of the throttle blade being shut and if your valve seals are bad it will suck oil from the valve cover into the engine.
and also as they get worse it will smoke when you first start it after setting for a period of time because oil will drip from the seals into the engine.
hope i helped.
