Recently I have been noticing a burning oil type smell coming from the car. Initially I attributed it to an exhaust leak at the clamp point for the new exhaust that I haven't gotten to weld yet. However today the smell was much stronger than previously noticed and my wife noticed smoke coming from the hood (I never saw it but she saw it multiple times). We parked the car until I can look at it tomorrow but I was wondering of any of you had any clues as to possible cause or area to look? The car has been cranking slightly longer after stationary periods but there are no other symptoms. Car runs great otherwise.
