I'd pull the eng & do the rear seal again & get that taken care of. I know it's a pain but it unfortunately has to be done again because you will never be happy with the drip & it likely will get worse. 80 is slightly too high & unnecessarily wears the intergear etc tho it ain't a dealbreaker being a bit too high but with the easy access of the BB spring I'd shorten it some more. 8-10 psi per 1000 rpm is plenty. I'd be wondering more about the rest of the oiling mods
