Car is a 99 V6/auto convertable and is my girlfriends car. Car has 102,000 miles on it and as I was doing a spark plug change, I pulled the drivers/3rd back plug(the one at the firewall). I noticed it was covered in some oil and the ceramic part was kinda worn down.
All the other plugs looked decent. The car has always ran fine, if not great. Got plenty of power, no oil issues or smoke and sounds good(no funny noises i'm aware of). I think it does have a pass. side exhaust leak, which seems to be verified by the searches i've done on here, as a common problem.
More concerned about that plug/cylinder, though. I'm thinking if the car is doing everything great, that it could possibly just be like a valve stem seal or something. When I changed the plugs it had sat for about 4 hours so I figured that gave it some time "drip".
Can any of you guys help me, or confirm what I think is possibly the problem. I know alota you guys "mod" these cars, but this one is just bone stock so it's had no "harsh life" to my knowledge.
Thanks for any and all help, i'm just not too car savy as i'm still trying to learn things on my 4.6.
