Not sure if it's baffled... came with it .. here's a picture .... it has a pvc valve installed ..I got spare ones too
I prefer to use the factory "turkey pan" with a ring of sealant around each intake port. Keeps the hot oil off the bottom of the intake. An oil leak into the intake usually will show on the spark plugs, pull them and see if you have one or two that don't look like the others.
Before you tear anything apart, are you using a valve cover with a proper baffle for the PCV? Oil disappears pretty quickly if it's not baffled.
