Oil is on 1 spark plug more than the other 3 plugs...My dad take them out and dry them off and it will run good for about 2 to 3 weeks and then it starts to cut back really bad. (hesistating till it gets up to full speed) I just wanted to know where is the oil coming from thats leaking down in the plug area.
What is the problem when oil is leaking down in the spark plug area. on 1997 Pontiac Grand Am
I say the valve cover gaskets need to be replaced. Both of them. Yes both!
