Can't quite figure this out. I drove the Jeep yesterday (2+ year old rebuilt 360 with , new timing cover, new pump and plunger spring ~9K on all of it) Oil pressure was 30-35 at 60-75 mph and dropped down to 10-20 at idle. Parked it last night, woke up this morning and started it with no oil pressure. Let it run for a couple of minutes and still no pressure on electric gauge. It did this last year, but I changed the filter, oil, plunger & spring and op sender and it seemed to solve it last year (or it got warmer I don't remember) Any ideas? Is something getting in the oil to sludge it up or freeze it? It is 10w-30 Mobil 1.
Also, my hot oil pressure keeps dropping. Does that mean worn rod bearings?
Thanks in advance...I think
