Engine problem or normal?

[flatheadmurre]

Even badly worn engines with zero pressure at idle usually goes higher then 12 when rpm is increased...
A little history on the engine perhaps what has been done to it ?

I agree with all the others----if the readings are accurate the oil pressure is wayyyyy too low. Need to find that problem first. Follow JSeery instructions if they apply to your system.

If the radiator cap is a pressure regulator there should not be puking unless the rad. is overfilled.

Motor was rebuilt at reputable engine shop. It got a whole makeover with new parts. Runs great and not looking at oil pressure allmwould seem perfect. The gauge is a factory gauge that was just restored.

I had a engine re built by a shop that has/had a good reputation and i put the engine in. At first the oil pressure seemed good but after a few day's it drooped off. So out it came. Sent it off to another shop and they found that a gasket had been installed on the oil pump that isn't required and it blew out.
