Question about 2003 Jeep Grand Cherokee
This morning my the "check gages ligh was on.. stay on when I stopped but when I star driving turn off..Please any ideas?? Thanks
It could be worn camshaft bearings that is lowering your oil pressure. I had the same situation with my 2000 Jeep Cherokee 6 cyl. Changing the oil pressure sending unit did not make a difference. I used a higher viscosity oil and that prolonged the life for almost another year. If you put an oil pressure gauge on it and let it run at a prolonged normal temperature, it will give you a definite answer wheter or not the engine has low oil pressure. The real problem is finding the cause. Camshaft bearings are a likely source. According to the spec book, the I-6 engine had low oil pressure numbers to begin with.
