You need to find where the oil is coming from its hardly likely to be coming up from the plug itselves unless its loose and you have an head gasget problem which is hardly likely ,so it must be running down into the appeture perhaps the rocker gasket leaks or there is an oil pipe leaking in the area .Are you sure its not petrol coming from leaky injectors.
