I have never ever understood the bike mechanic/bike assembly mindset to tighten pedals down as if they were wrestlers and the pedals were the puny announcer they just put in a headlock. The pedals are threaded so that they tighten with each pedal stroke. I grease the threads, turn them tight and then give them a little more *snug* with the wrench. That's it 'cause that's all they need! Sorry to hear about the insert and I hope Campy fixes it for you. If they don't, ditch the square taper and go ultra-torque...now that is some sweet Italian hardware right there.
