<VV> Repairing a failed crankcase stud thread repair

[Roger Gault]

I had to go all the way to 5/8-11 UNC to get into good metal after two of my
PO's short helicoils pulled out.  Been in there about 20 years now.  I had
some 5/8 setscrews tapped.  Use a bolt - the setscrews are WAY to hard to
tap.
