Yeah the coils are good. But then again that specific spark plugs doesn't have a lot of oil on it, it'* just a noticeable amount of oil on the thread and carbon on the electrode. But this is the worst looking plug out of the 6. The plugs been in my car for about 3 months.

I've had positive & impressive results with Bar'* Engine Oil Stop Leak 'With Seal Conditioner"

Changing to a different plug may not be the answer if you have other problems causing the fouling.

One of my lifters does tick when I start the car, could this be a problem? Could any information from a scan tool point me in the direction of my problem, such as IAC, IAT, o2 readings and such?
