My oil pressure buzzer and light went on recently when i was driving over a
mountain pass. Pulled over and checked oil, it was fine. Temp was fine too.
Kept going. Buzzer and light went off again. Went home and changed vans. The
mechanic said the oil pressure is 9 lbs. at idle and 20 lbs. at 2,000 rpms
and the factory min. is 29. He recommended a rebuild. The van drives fine
around town. No suspicious noises or weird behavior. There is a tiny oil
leak, but very little. Do I really need a rebuild? I would like to get it
road reliable, so any suggestions as to what things I should get checked out
or fixed are very welcome.
