Well,
After killing 2 6mm allen sockets (sheared 'em off!), I finally managed to blow out the internal hex of the block's coolant plug on the left side of my M119. Unfortunately the plugs hex died when it was approximately 1/2 way out. It is not leaking at 15psi. and has shown no signs of leaking when run, but I'd like to get the darn thing out and put in a new one (w/ some antiseize!). I am considering using a combination of heat and an extractor, but I am concerned about breaking off the extractor's tip. Anyone have any suggestions out there? Fortunately the right one was easy to remove! Thanks in advance for the suggestions.

Andy
