REPLIED

Unfortuantely is possible for you to have the piston rings worn out,and for that you need to take apart the engine.

i have oil in both bank of the engine, could a bad manifold gasket let oil seep into the heads?

ACCEPTED

It is possible that you have a leaking intake manifold gasket.Also if your cyl. were egg shaped replacing the piston rings would not stop the oil from getting into your cyl.Other possibilities are-rings are installed incorrectly-valve seals installed incorrectly.Did you mic. your cyl. and pistons to check the clearance? This is necessary to assure proper piston ring seal.Cyl may have needed machine work or pistons were worn.Most likely you are going to have to take the engine back apart to check things out.There are several reasons for the oil being pushed through your engine.
