The spark plug may be especially exciting to drill for an easy-out, since it's filled with a ceramic core and won't drill, but seems to me that when I took one apart a long time ago (to make a leakdown tester), the ceramic center insulator just lifted out once I ground off the upper part of the body, so maybe you can actually pull the core out (if it isn't already out) and then try heating it with a torch (exciting...) or saw a slot from the inside (use a slimmed down hacksaw blade) to loosen it, prior to using an an easyout. (since it was tight enough to break off in the first place , you really need to loosen it up somehow first). The two kinds of stud removers I've seen are the easy-out type, which has a fast spiral reverse thread, and one that just has tapered, non-spiral sides which you tap in. I think the easy-out type works better. You can get pretty big easy-outs. Dave At 10:06 PM 7/20/98 -0400, Gary Edwards wrote: >Ah! Brilliant deduction, Sherlock.
