To those who think that the bolt might have been loose from the start,
remember: I watched the shop build this engine, and I personally saw them
check the torque on the engine case bolts. They *were* tightened to spec.

I also know that they never re-checked them, however, and my main mechanic
has admitted that they never check these as a matter of course.

Now, I am not an A&P, but is it possible that when the bolts were torqued
that they needed to be torqued in a particular order, reminiscent of
tightening lug nuts on a wheel? Sometimes when tightening several bolts, the
action of tightening later bolts causes the first bolt to become loose. In
this scenario, the last bolt is torqued correctly and the first bolt is
fairly loose. Just thinking here....
