Our 04, 9 5, ARC, wagon, 49,000 miles, started leaking oil on the passenger side of the car. I put a wrench on the oil drain plug and it was tight and while under the car look up and noticed it was "wet" with oil much higher up on the engine.

Does anyone have an idea where it might be leaking and how much this may cost to fix?

 

valve cover gasket,head gasket,rear main seal try to trace how far up the leak goes,take some pics and post them it helps to see the leaking
