Re: Advice on removing snapped s/s bolts from alu block
For $240 for a new block, you don't have much to lose by trying to drill and tap. I used heli-coils on motorcycle spark plug holes and was not aware of leaking but if in a water jacket you wouldn't know until you re-assembled everything. New block looks better considering your time?
