They all leak at some point. Valve covers tend to leak after they go off and on several times (when the gaskets are totally crushed).
Oil pans seem to seep, stock or after
market, I thought I had a rear seal leak, actually my brand new 10 qt. Canton on my FE motor was seeping. Thghtened it and now good to go. Had a few other situations , one leak by a bolt on the
oil filter adapter plate...dumb things like these.
Don't fret it's just a FORD.
