I bought my 42 Carver last year. It saw a new short block (454 Gas Mercruiser)on the starboard side just before my purchase. The port oil pressure runs at 40psi. The star. shows ~80 cold and ~65-70 at oper. temp.

Question:
I am seeing a fair amount of leakage in the bilge. Could this be the high pressure forcing oil past the rear seal (assuming the oil guage is accurate)?
Is there a way to adjust the pressure?

There is no way to adjust the oil pressure on a 454. Have you put a mechanical gauge on the motor just to verify pressure? The oil pump is mechanically driven, located inside the oil pan, and it has a high pressure relief valve that I've seen in rare cases be defective and stuck shut. BUT in order to change the oil pump, you need to drop the oil pan, and that's probably a major job in your boat.
