I need to change the valve cover gasket and decided to change plugs at the same time. The car is 18 years old with 75,000 miles. I am concerned if the original plugs will come out without damaging the head. Should I let some WD-40 soak down at the base of the old plugs to help loosen up threads? Thanks Bob. Also, can you reset a service engine light by disconnecting both battery terminals for a few minutes and reconnecting them?
