Back in the day, If we were pumping too much oil up to the top end , we'd put pipe stem cleaners in the push rods to limit the oil coming thru them. It works and its cheap....GlennK

My idle pressure @ 850rpm hot is around about 25-30psi. What sort of other damage could excessive oil pressure cause? I was told by some that if there's lots of oil in the top end of the engine, then there's problems with lubrication down low.
Don't confuse oil pressure with oil volume. Pressure comes from a restriction and it doesn't affect volume. If the volume were to much and the oil is uncontroled then you could get too much oil in the heads and eventually run out of oil in the pan. If you have a high restriction this is a good thing. It means the tolerances are still close. If you have volume to compensate, oil pressure will remain high even though tolerances ar bigger than spec. It 's a cheap way of compensating for worn out engine bearings. I would recommend you change pumps or relief springs with 90 pounds at RPM. Your just overheating the oil and it's costing you power. As much as 15 horse in some cases.

Is this too much? Can it cause damage to anything?
I am the last to day I know a lot about engines just listen and been learning. But mabe a mechanical gage to check the pressure if the one you are using is electric. Ed ke6bnl

I tried using both types of guages, but without a different result between the two, So I just keep using my current Autometer, which is mechanical.

If you are worrying about too much oil to the topend, grab a set of roller rockers, which have a much smaller oilling hole and will lower the amount of oil to the topend.
