Hello I started getting an oil smell inside the car. The mechanic said that oil is leaking on top of the exhaust. But they couldn't see where from. Sothe added a infrared dye to the oil. The reading in the oil is pretty high so I am thinking may be too much oil. Has anyone had this problem before?. My car was using 1qt of oil every 2000 miles but it stopped last time I too k it to the dealer for the 90k service. Could it be that the valvoline oil service place is doing something wrong?
