Im Hoping somebody can give me some advice on this, Im currently trying to take the head of my Rabbit engine off to get into the Cylinder #1 because of a blown glow plug fragments still sitting inside the cylinder. I'm trying to take one of the Cylinder Head bolts out, and the thing wont move. I've gotten 7 out of 10 bolts removed. I've Broken two 10 MM polygon socket head pieces, as well as a 3/8 short extender. (Yea.. the tool head just snapped right off). I was using a 3 ft PVC pipe to put some leverage on it. I know im putting too much force on the tool. How can i resolve this? Could the Bolt be somehow Fused to the engine or something? Any suggestions would be greatly appreciated. Thanks!
