After disassembling half the engine it seemed like to be able to get to all four plugs the fourth one decided it was going to snap inside. Upon taking the first turn of the socket wrench I felt a scraping sound like sand. Immediately I knew that wasn't good. The other three came out relatively painlessly.
I tried re tightening only to notice it wasn't happening either. I grabbed the end of the plug with my pliers and the guts of the plug came out. The shell and the tip are still in the channel. It appears the threads have become almost fused to the channel probably due to over heating. When I turned the head with the wrench the top of the plug twisted free from the rest. The core of the plug that came out is ceramic.
I'm at a loss how to remove the rest of the plug...
Any ideas?
