I already read the FAQ
Q: I changed my spark plugs and one or all were full of oil, what’s wrong?
A: Your spark plug tube seals need to be changed. It’s an easy job and the seals can be bought from any auto parts store or the dealer. You will need to remove and replace your valve cover gasket as well.
Did that still have the same problem. The well is leaking from the bottom not the top so its not the ^@()^%*I)^%(^)% tube seals.
must be the tubes themselves
or a cracked head?
