Thanks for the reply jay_bob. I've changed the plugs a couple of times over the years. Had to drill one out once. I now make sure I do the job with the engine warm/hot and always use anti-seize on the new plugs. As little as I drive the car, I think I'm just going to let things ride unless things get worse. The job just isn't worth it to me at this time.

I don't have the kit you have, but I do have the correct tap, sockets, etc. to hopefully make things go smoothly. Thanks for the offer - I'll keep it in mind.
