u mean the spark plug snaped in half? probably going to have to take the head off and twist it the other way if not a machine shop can always get the job done.
Well, he said he thanked " EZ OUT". An EZ Out is basically a backwards threaded remover. You drill a hole in a broken bolt or stuck stud and then twist it in (again, backwards thread) and when it bottoms out you keep turning it and PRESTO, out she come! They come in usually 3-4 different sizes and are available from Sears and many other tool sources. Good luck.
Well, if it were a bolt you’d want to be sure that you didn’t drill all the way through. You want the EZ Out to stop at the bottom of a hole before going all the way through. I can’t tell you how to deal with a spark plug since I’ve never seen a broken one. The core of it may already be hollow. You might just tap in the right size EZ Out and then start turning. You SURE don’t wanna dump that crap into the cylinder though.
