Sounds like blow-by. Does it smoke? Have you done a compression test? The only thing I can think of is leaking piston rings. Was it just rebuilt? were the cylinders checked for excess wear, bored. honed, etc.

Could be normal.
Is the PCV correctly installed on one valve cover, and the other valve cover should have a breather with tube going to the air filter box?
Some put 'sealed' valve covers on, then question why the oil filler cap blows off, spewing oil everywhere.
