I actually took the car into the dealership for a dx checkup before I changed the plugs and discovered the oil. The car has a hard rev problem. They told me it was the MAF sensor. He disconnected it and the car ran perfect, but smelly (rich). Today my local mechanic told me it was probably the head gasket. How strange it is to describe the head gasket in Italian. I still don't know if that is what he said, but he did say that it will not stop me from driving the X. That is good.

Hey Maxskibum, any idea on how it took you to change out the gasket? Driver's side or passenger's. It took me 2 - 2.5 hours to do the plugs. I didn't think that I was that slow.
