98 12 valve main bolts keep turning
Rebuilding this 12 valve, got new bolts from Cummins and several of them keep turning and won't come to final torque of 130. Started at 44, then 88, and a couple went to 130 but others keep turning. Does this mean they're stretching? The book says to go to 130 with no additional 90 degrees mentioned. The bolt heads have a T + 90 on them so what torque do I stop at? Have I damaged the ones that have kept turning? Probably 180 degrees past 88 ft lbs while looking for 130. Torque wrench is a Snapon that just came from calibration. It repeats good torques when I get them.
