After watching my oil pressure gauge read 20psi at cold start and decrease to 1-3psi after about 20min of driving I began to worry that something might be wrong internally with the engine or that I have a bad pickup. I bought a mechanical oil pressure gauge / test kit and discovered, much to my delight, that I had 60-65 psi at cold start and 55 psi or so after the engine was up to operating temperature. I am certain now that either my gauge is the problem or the sender is bad.
As far back as I can remember the oil pressure has run low but used to be steady at 15-20 psi and my Dad who had the Jeep since 1999 saw the same. The Jeep underwent a full restoration and the old wiring harness was replaced with a painless but I kept the original sender and gauge. Does anyone have tips for trying to get an accurate oil pressure reading with the stock gauge? Should I get a new sending unit and if so, are the typical Omix ones worth it or should I go with another generic sender that uses the single wire? Is there any way to test the sending unit with a multi-meter?
I would like to use the stock gauge if I can.
Thanks
