Idle Oil Pressure
 

Ok i did a search for this question and i didnt find anything, might have looked for the wrong thing not sure. Ok i have a question about my oil pressure i have a N/A motor and and when i sit with the car idling it slowly drops from 40psi to below 10 i think whatever is the lowest on the gauge. Dont know if this is a problem or not. I was kinda think that my oil pump was goin out so i am wantin to see if that is something i am goin to have to tear into motor for or if this is a normal thing

:help:

So I am going to assume that is normal, because engines usually rev up a little bit when started up. I guess as long as your above 4.3 at idile your ok.
