Oil doesn’t appear to be coming valve cover gasket, top down staining. PCV? Oil cap? I’ll pull a coil pack and see if there is oil in there from the inner valve cover gasket seal, but if it was from there and leaking that much, it would def cause a misfire or something. Runs perfect. Any ideas? Could just be blow by….

    In your 3rd pic, you've got oily little rodent footprints on the rubber air intake. They want to eat up your wire insulation.

    ^ therefore your problem could be rodent piss, not oil.

    Add some sticky traps under you hood at night where you see foot prints, see if your oil leak goes away with the mice..
