HELP - Broken Sparkplug
We had to change the manifold on the truck. Its a 1994 F250 with the 351 in it. The drivers side manifold had a broken bolt in it, so we got the manifold off, had to melt the bold out of the block. The truck has 84k on it, and dont think it ever had a tune up. The spark plugs looked as if they were welded into the trucks block. We managed to get 3 of the 4 out. The 4th plug broke off flush with the block. Its ready to be put back together, but how do i get that plug out? Any help would be great. Thanks everyone!

You can try to remove the center ceramic portion of the plug and using a torch and a large screw extractor remove the outer portion of the plug. However, In these situations I have had to break the center of the plug out, and chisel with a punch the remainder and pull it out. It is a very unfortunate situation but there isn't much you can do short of taking the head off.
