I have changed the oil pressure sensor twice put a manual gauge on the block to see if dash gauge and scangauge are correct. They are. Cummins quick serve says only 4 things can cause high oil pressure and I would be eliminating 3 of them with a new pump. So while I'm doing it should I put the dimes in or not?

acutal high oil pressure could also be a failure or blockage in the front structure gasket.

any recent inframe or front structure gasket/geartrain work?

No none at all.
