This has been an interesting thread. Very informative.

Dennis, glad to see you're out exercising the car after all that work! </div></div>
I just use a feeler guage, plus a wrench, and an allen wrench...(I've got poly locks). I've always thought I'd buy a go/no-go guage, but once you get a feel for doing it with the feeler guages (that I already had), you can do it with your eyes closed.
