I noticed my car iddles rough and i found oil in one of the sparkplug cavities. it's flooding the ignitor lead and causing it to missfire. where could this oil be coming from? only one sprak plug cavity is affected.

The oil leakage is simply an indicator of a valve cover gasket leak, replace it straightaway.
