Ok #4 glow plug was seized but with a little pb blaster it started to move. Then the dang corers rounded off because I cranked too hard on the rachet.

Too tight to get vice grips on it and be able to turn them.

Only idea I have is to sacrifice a 12mm socket by filling it with JB Weld, pushing on the plug and letting it harden, then trying again with a rachet.

Anyone have a better idea?

Thanks!
