I would generally concur with that assessment, since this sort of thing
is not rocket science. The degree of difficulty only depends upon how
much of the stud is left. If it's broken off flush with the deck, then
anyone with a milling machine can plunk the block on the table, center
on the hole and use a center-cutting carbide (or TiN-coated) end mill
and cut a hole in the stud and use a screw extractor, or use a
left-handed drill to cut a hole in the stud center and use the drill
drag to loosen it. If broken off below the deck, then a simple drill
guide can be made in little time.
This sounds like someone just didn't want to bother with it. Take the
block to a shop which does diesel engine repair--they're usually
equipped to handle such eventualities. As well, anyone who does EDM can
probably eat out most of the stud to a point that only a threaded shell
remains, easily extracted.
