oil pressure

Asked by Oct 27, 2014 at 05:55 AM about the 1993 Jeep Cherokee 4 Dr Country SUV

Question type: Maintenance & Repair

My wife and I bought a 1993 jeep Cherokee. We are on a fixed income and trying to find answers to problems I may be able to fix myself. When I crank the vehicle, the oil pressure will start at 40psi, but as I drive it will go down to around 18psi and the gauge will only move up a little as I apply the gas. An example of a drive: We went to Wal-Mart, about a 20mile drive, and then shopped for about an hour. When we returned to the vehicle and started the engine there was a grinding noise that dissipated, and the oil pressure was still down to the 18psi and we drove home that way. If we let the car sit for like over night and go out to start the vehicle it will start back out at 40psi. Can anybody tell me what's going on? A solution to this problem would deeply be appreciated.

When you hit the gas or increase the RPM's, does the pressure go up?

If you have a grinding noise, I wouldn't suspect the gauge to be faulty, but the pump itself. How is the oil level?
