Re: lowest oil pressure for engine to survive
Old chevies of that area had 14 lbs. to the mains and to get oil up to the rockers.
The rods had dippers that were dipping into puddles that were full and running over with oil.
My dad had an old Oliver 70 farm tractor with a Continental 6 cylinder ohv engine.
The shop manual said, “remove the little oil galley plug and with the engine running the oil should barley trickle out. We worked hell out of that tractor and it never did quit and never showed any oil pressure. But those are different engines. Our V8s need at least 20 lbs. at speed
I’d drop the pan and check or replace the inserts. I’d also install an 80 lb. oil pump.
These engines are getting scarce.
