[QUOTE="95PGTTech, post: 11988445, member: 55701"] My honest suggestions from the other information you have posted would normally to do a compression and leakdown test to confirm a diagnosis on the bottom end without needing removal of the head. I have never had any luck with a boroscope. Unfortunately probably not possible with the damage to the cylinder head threads. Based on the way the plug is smashed in, I'd likely suspect ring lands, a piece of which did in the electrode. Absolutely do not drive the car, even with spark and fuel disabled to the cylinder. If the ring lands aren't toast and a piece of that thread gets on top of one of the rings it will be like running a razor up and down the cylinder wall. If the ring lands are gone and catastrophic damage has not been done at this point, running the cylinder would be like taking an angle grinder to the cylinder wall. [/QUOTE]
