I have the opposite issue in my recently aquired RN, I have more than 10 PSI plus even when warm. At turn off the pressure dissapates slowly so I think that symptom rules out any issue with the pressure relief vave setting.. It has the high capacity sump. I have checked the squirters are clear. The last person to carry out any work on the engine is now deceased but I do know he had a mod for the oil pump and did something at the rear camshaft bearing to increase oil pressure. I know this as he and I rebuilt the engine of a 1935 rodster I had a few years ago. The mods did not seem to make much difference to the oil pressue of that engine. I have driven this car less than 150km but it runs nice and sounds fine. Should I be investigating furthur?
