Wierd oil pressure problem - Drops to 0 at idle!
Ok guys, I did some searching. And I have yet to find any kind of answer to point me in the right direction.
My 2000 XJ is having, what I think, is oil pump problems.
Under normal driving conditions, about 99% of the time, my oil pressure is PERFECT. No issues what so ever. Runs about 60 under load and roughly around 25 to 30 cruising... 10 to 15 at idle.
I noticed the other morning going to work while I was sitting in traffic that all of a sudden my CHECK GAUGES light came on and I had 0 oil pressure. I paniced and shut the motor down. I got out and checked everything over and visually, things looked OK.
I started the Jeep back up, perfect oil pressure. After some more head scratching I drove on to work. A few days later, it did it again!
The condition is this....while at idle for more than a minute. My engine's oil pressure drops to 0! However, works perfect at all other points in time. And when the engine drops to 0, you can slightly rev the engine to ~1000rpm and viola! oil pressure comes back. Something else that is wierd...it does not do it all the time. It is sporadic, seeming to do it only when the engine temp is at normal operating temp.
Any advise would be appreciated!
