M10/E12 conrod bolt troubles

[digger]

Great idea, next time I do a set I'll test the old ones. BMW says you can stretch them up to 5x times so a used set should give us 1-2 tests per bolt and maybe depending on what I find I'll get some new bolts and test too.

looking at the stretch gauge (ARP) it is in half thou resolution (not accuracy and some brands are worse at 1 thou) so that is in the order of 10% of a typical stretch so may not be able to differentiate much accurately/definitive. Will be interesting to see

You mean 10 or 11 ugga duggas isn't the correct torque for these?
