I've broken the insulator in the rear of my 455 Trans-Am several times. Sounds like the socket was not on the plug all of the way. Now that the insulator has broken off, you may be able to get a normal socket wrench on it, it is smaller than a spark plug socket and will give you more room and possibly more leverage. You should still be able to unscrew the plug like normal. If it is stuck, try spraying some penetrating oil on it first and letting it set for a hour. This will loosen any rust that is preventing it from turning. Hammering it will damage the threads and possibly crack the head. A torch will warp the head. If all else fail, you will have to remove the head and take it to a machine shop. A pain, but better than buying a new cylinder head!
Step 1 Spray around the threaded area with a light penetrating oil like Liquid Wrench or Kano Kroil. Allow it to soak in for 20 minutes or more before trying loosen the broken plug. If this is the first spark plug that you attempted to remove, it's not a bad idea to soak the others. Usually if one is in poor shape, the others are probably not much better. Once you have decided that it has soaked enough, continue to the next step.
Step 2 Get an EZOut the size that will fit the hole where the ceramic used to be. You will need a very large EZOut Extractor. An EZOut (or Easy-out) is similar to a drill, except that it turns in reverse. As you turn the EZOut counter clockwise, its teeth grip the interior more tightly and turns it.
Step 3 Insert the EZOut extractor into the shaft where the ceramic part used to be. Make certain that the EZOut is the appropriate size. If it's too small, the teeth will not grip the sides.
Step 4 Turn it very slowly and carefully to unscrew and remove the old spark plug.
RE: Broken spark plug in motor....How to remove? I was changing the spark plugs of my honda civic '00, I managed to take out 3 of them the 4th was really hard to remove, after a while the ceramic part broke leaving still stuck the piston par
If it is only the ceramic part of the plug broken, there should be a steel six sided part in the hole. Look at one of the old s/plugs, and compare. If the hex part is still in the hole, spray around the outside of it with a good quality penetrating fluid. GM Makes a good one called "penetrating fluid". Allow it to sit over night. Install a good 5/8 socket on the remainder of the old s/plug, and start to loosen it. If it turns a little, give it some more spray. Keep working the broken bit, back and forth, while keeping it lubed with the fluid. If you get it out, good. Apply some copper coat to the threads of the new s/plugs before installing them, and you won't have this problem again. If it won't come out, take it to your dealer.
