The oil egine light on the nissan navara d22 model is flickering what is the casue of this and the oil level is fine?
The oil light is the oil pressure warning light. When it flickers, it means the oil pressure is trying to build up, but can't maintain good pressure. It may be critically low which can cause engine damage. Have a mechanic hook up a mechanical oil pressure gauge to get the true oil pressure. If it's good, replace the oil pressure sender unit on the engine block. If it's too low, it may be a problem in the oil pickup tube and screen in the crankcase, clogged oil passages in the engine, a worn oil pump, oil too thick from wrong weight oil, worn crankshaft bearings, a failed pickup tube gasket or oil pump gasket. It would require some investigation to find the problem. But get the true oil pressure reading first, then you'll know if it's a problem or not.Is it the engine or the starter dragging? For your sake, you should hope it is the starter. Good luck, Cliff.
