OIL LIGHT FLASHING

2005 Mitsubishi Challenger

2005 Mitsubishi Challenger 6 cyl Four Wheel Drive Automatic

have recently noticed oil light on. Have performed an oil and filter change the light eventually came back on. Replaced the oil pressure switch and again the oil light came on. Seems to only come on when vehicle is hot and idling

Check the oil pressure with a mechanical gauge to rule out the oil pump pressure relief valve could be sticking open or the oil pump is failing and worned engine bearings
