Thoughts on this oil seepage
As previously said, those Mopar Performance Valve Covers have to be notched (trimmed) at the Intake Runner area or the Valve Cover does not push down on the head (gasket) properly, and the intake bolts need thread sealant or oil seeps up the threads and pools around the intake bolts. I used ARP thread sealant. Edelbrock makes a Air Cleaner Base Plate that has a push out hole to put a connection on for the Oil Breather hose. You can keep the top of your Air Cleaner.
