Replaced rear main seal twice and still leaking oil. We replaced PCV system as well. The oil is coming from Crank bearing cap area not the seal. Is there something we are over looking?

rear main bearing is worn out and wobbling. there is no seal that will keep this from leaking.

you need a rear main bearing
