Can someone tell me what develops the oil pressure in an H? Is it the cam bearings, main bearings, rod bearings, or???
I finally have to admit it, the oil pressure on my H isn"t what is should be. It starts out at 45 pounds on a cold startup with fresh SAE 30 oil, but with the engine fully warmed up will barely hit 10 pounds at full throttle. This is a 1952 H, my father-in-law bought it in 1958 and it"s been in the family ever since. I"ve owned it since my FIL died in 1980. I"ve never done anything but normal maintenance and I don"t recall my FIL having anything major done to it, so it"s possible the engine has never been gone into.
It still doesn"t smoke or use oil, compression sounds even across the board, so I"m wondering if replacing main and rod bearings would help, or if I need to go further. Any input would be appreciated.
