Heli coils are great but by his description it sounds like what he did
was round off the drain plug rather than strip the threads. I would get
a 6 point 1/2" socket and hammer it onto the plug very hard. Then it may
well come right out. The 1/2" is slightly smaller than 13mm and the 6
point socket will bite into it much better than a 12 point. If he had
used a 6 point 13mm in the first place the rounding of the head would
likely never have happened.
