What should the oil pressure be for a 4.0 at idle? I just recently noticed that it's at the "quarter" line when she's at idle and that concerns me. Thanks!
If you have 10 lb or more at idle your fine. Stock guage is pretty vague, best bet is to T in an analog guage under the hood with the factory sending unit so you have a real reference to actual pressure.
