I have a mechanical gauge with the clearish
oil filled tube going to the port in the front of the block. I have always heard rules of thumb like 10psi pressure for every 1000rpm, etc. but this thing just sits steady all the time. There is a fair amount of air in the
oil line to the gauge but from what I have read, that shouldn't make any difference because the pressure is such a low range it doesn't really compress the air much and it doesnt take much pressure to move the needle, etc. So don't need to bleed that air out from what I can tell.
So, I'm just stumped how the gauge can be steady like that all the time. A mechanical gauge like this should be moving. Doesn't give me a good feeling when
oil pressure is the life of the engine. Any other thoughts?
