Oil leak from below valve cover gasket, replaced distributor o-ring, was told by mechanic it's not head gasket. Was told it might be oil pressure relief valve base plate??? O-ring?. Oil leak slow.

Any updates to this? Can you provide a picture (or several) of the areas with the most oil? And do you own an inspection mirror? If not, look into getting one, they're great for issues like this. Long flex handle with 1.5" ish mirror on the end.

Good idea, I'll try to get a mirror. Thanks, I'll try to get some pics up too.

Ralph, how's it going? Did you figure anything out by looking around behind the engine? If you still need some help, snap some pics sometime and throw them up here.
