Dodge Ram 1500 Pickup 2WD

My friend's 1997 Ram 1500 pickup is "sucking oil" (his words). He says it's because the intake manifold plenum gasket is bad. He says replacing that gasket fixed the problem once before. He adds that it has something to do with the PCV system, but can't explain it further. I don't see how replacing this gasket would fix the problem unless a bunch of oil is somehow leaking over top of the trans and burning on his exhaust. What do you think?
