I've got a TRX 2.5 with some aftermarket head. I was tightening the glow plug with a socket wrench (engine head is too tall to use standard glow plug wrench) and I accidentally jerked over to the left and the hex part of the glow plug broke off from the threads. The threads are still in the engine so there is no opening I believe.






The only thing I can think of to get it out would be to remove the engine head, get a very clean rag, cut a hole just big enough for the glow plug to fit, and use some pliers to screw it out. Is that what I should do?
