Things were going smoothly till the tip of the extractor snapped off down in the hole.
I tried a center punch to shatter the extractor tip, with minimal progress. In frustration I found a hardened drill bit and tried to drill through. Of course that snapped off too.
Now I have the remains od the extractor and the bit in the hole.
I decided to walk away and research my options.

If it were me, and this is just me talking....I'd mask off the block and surrounding areas with some weld proof material and fill the area with weld and weld a nut onto the broken bits and get it out that way. I had to do this with 3 exhaust manifold bolts that broke off in the cylinder heads, it worked great. It took some planning, prep and patience to get them all but that was the only way for me.
