1997 Chevrolet Cavalier Q&A
1997 Chevrolet Cavalier Question: I'm trying to determine if I need to replace my oil pump or put a new engine in.
My oil pressure light will come on when I'm idling at a stop light/sign. I've had the oil pressure sensor replaced and the light still comes on. I've also noticed that when I go up the mountain, the oil pressure light comes on then but not when I'm going back down the mountain. I've been meticulous about doing my oil changes every 3-4000 miles. I currently have 168,000 miles on her. - Lesboop
Down is not bright normal, I think no big problem - applecycy
take oil pressure switch out and hook up a gauge that will tell you if the oil pressure is within specs - goodguy
As goodguy said you need to check the oil pressure with a gauge. If the pressure is out of spec. I would replace only the pump assuming you have no unusual internal noises from the engine. - Chevy Power
have a manual oil pressure test done to determine issue but don't drive car as to damage anything just in case - globalhelper
