Bingo. Eyeball judgment says that the lower hole is also just obscured by the
upper edge of the water pump, which means that has to come off also. If the
thread that's in there is not too badly gored out, I am planning to make a
temporary repair by cleaning the threads (even that means I have to cut a tap so
it's short enough to clear the water pump) and putting in a stud so I stress the
remaining threads as little as possible.
I just want to know what the original thread was (coarse or fine) so I can do
this without doing any more damage. When the engine comes out, I'll Helicoil
that hole, but I would like a short-term solution.
