Hey Scotty! I broke a bolt off in my engine block trying to remove the water pump. The head snapped clean off. The shaft is still sticking out about 1.5" from the block. I've tried to use Vice grips, Penetrating oil, and heat form an acetylene torch however the bolt will still not move. Do you think I need to try more heat(as the bolt didn't get red hot)? Or am I going to be forced to drill the bolt out at this point?
more heat, make it red hot and it will come out, just don't start any fires
