What kind of pressure #'s are you looking for ?...and WHY high pressure at lower rpms ?




I recently bought a higher mileage 318 powered ram, looks like oil hasn't been changed in a L O N G time due to a rounded off, stuck oil pan drain filler plug.

The oil pressure gauge still reads slightly below half scale all the time, no engine noise that I would associate with low oil pressure.

I'm going to be swapping oil pans soon, thought it might be a good prevenative measure to change the pump out with the pan off?

Perhaps I will just clean the pick up screen and let it go.
