my friend has no oil pressure when the car is running and driving. also a little bit of white smoke out of the exhaust. There is an oil leak but cant find the leak. Seams like the oil is appearing on the top of the hood latch but that does not make any sence. I am stumped. I was thinking the oil punp or sending unit or something like that. The car does not over heat so i dont think it is the head gasket. Also he can smell oil when the car is driving.
