Engine Mechanical problem
1991 Chevy Blazer 6 cyl Two Wheel Drive Automatic 200000 miles
when the engine gets hot the oil pressure goes down and the check gauges light comes on when at idle at a redlight. I have to put the transmission on neutral and keep the idle up to maintain oil pressure. Would replacing the oil pump fix the issue or would it be something more complicated like crank bearings or sensor?
