I'll bet they were either too tight before, or are too tight now. If
the bolts have been over-torqued, the threads may be deformed enough
that they won't stay secure - you may need to use inserts on all of
the holes. Still, I would try using a straight pan and a little anti-
seize on the bolts and then torque them and see what happens. I've
had much better luck with pan bolts since doing it that way. When the
bolts are too tight and the pan deforms, the tension on the bolts
doesn't stay the same and they come loose.
