I have a 1972 Oliver 1855 diesel that after initial startup, will idle around 55psi oil pressure and at 2000RPM its around 75psi. After using it for over an hour, oil press drops to 15-20psi @ idle and 35-40psi @ 2000RPM. Has anyone run across this before? Could it be oil pump? gauge? It runs great with almost no blowby or leaks. After its shut off and cools for 30 min or so, it will have good pressure again. Any help would be appreciated! Thanks
