Never had this happen before. I was removing the plugs from my '89 Cressida when I noticed the ceramic electrode insulator on one was broken. I looked in the cylinder with a boroscope and sure enough, the missing piece is sitting on top of the piston.
Obviously, I need to get that piece out but so far have been unsuccessful fishing it out with a 4-finger grabber. It's large enough that I imagine the grabber could hold it, but it's kind of off to the side (couldn't be conveniently right in the middle, hell no) and of course I'm trying to do the grab blind. Tried a shop vac with a piece of vacuum hose sealed off with duct tape to the larger wand and snaking it down there to suck it out, but so far that hasn't worked. I tried slicing the end of the hose at an angle to increase the opening, but no go so far.
Any ideas? I'm not sure what I did to cause it to break off like that just unscrewing the plug, though it was a bit stubborn coming out.
Thanks for all input.
