Decreasing Oil Pressure
courtesy of Bob, The Auto Answer Man
I am having problems with my 2000 Jeep Cherokee Sport. After the vehicle has been running approximately 10 minutes, the oil pressure gauge drops to zero when I am at a stop. Once I start driving again, the pressure rises, but not to the normal level. My mechanic has had the car for over a week now trying to diagnose the problem. Do you have any advice or suggestions?
It's a worn out oil pump or bad gauge. I would first install a mechanical gauge to verify that there is an oil pressure problem and not rely on the electrical gauge (they are known to be faulty). Then, if it is determined to be a pressure problem, I would look at either the oil pressure bypass or the oil pump itself.
