I have a 97 sc2, acouple months ago I found oil in the spark plug hole on top of the valve cover I think its just on top of the spark plug but I can't really tell if its in the cylinder too. I clean it out when I change the oil but it fills right back up afterwards, also theres oil that seeps out under the valve cover. also I added that restore stuff from walmart awhile back thinking maybe it would help, but now I've got this white stuff that clogs up my pvc valve all the time and I have to clean it out all the time. my service light has been on for awhile too I'm not sure if that related to the oil leaking out or not. I was told by a friend it could be some ecu software update that saturn has to install. I'm thinking my head gasket is going bad but I just wanted some advise on it.
other than that my car is running fine so if anyone has any ideas whats causing the leaking and the service light I would be very grateful.
