I changed the plugs in the cobra only to find bad news. They were the original plugs from 1996. I found oil on the #7 plug. It was between the electrode and the seal before the threads. This makes me think it's "blow by" Is there anything else it could be? I hope. I just got the car and this really sucks! The car runs really good, so I don't see how something could be wrong. Any and all info would be very helpful>.
