yep...it was a piece of an extractor....
the good news is that I put some more hate into it, used a small punch, then worked a burr some more into the broken extractor, then put my shop vac on it and had a geyeser. I guess the previous hack drilled all the way thru the bolt into the water jacket.
At this point I think I'm better off as I can heli coil it or time sert it now that the hole is obstruction free. All it took was a little more hate.
