So, I have a 2002 Grand Prix GT that's been progressively leaking more oil. The rear main seal was replaced a year ago, the valve cover gaskets were replaced in the safety recall and the oil filter has no oil around it. The oil leaks very steadily, especially after driving for a bit, from the passenger side. The bottom is covered with oil after driving, so it's hard to get a good look at where it's coming from, but could be anywhere from the front to the rear of the engine, on the passenger side.
My guess is the oil pressure switch, but I can't see it. Any opinions, wisdom or suggestions?
