Thanks to Kai and Dick for responses to my question. I also spoke with one
of the people at the lab where I work who is responsible for building
experimental engines. He says not replacing the bolts would be a false
economy. (After all $50 is only about 1% of what I have into this rebuild
<G>)
He also said they have a rule about how many times they will torque a rod or
main bolt. The bolts are marked with a punch each time they are torqued.
They use the old bolts to check clearances.
Anyway, I grudgingly ordered new bolts today. This doesn't hold me up too
long.
Regards,
Hugh Fader
