Engine Stud Retorque Question

[egolsen]

Quick update: 2weeks ago, I installed Xotic studs in my 13 6.7L Cummins.

The process says that after running the engine to temp several cycles to recheck the torque.

I’m running the equivalent to the ARP 2000 studs, not the 625s.

I checked them yesterday, and 5 of the 26 made a slight turn, maybe 15 degrees each.

Not a terrible job to recheck them.

Installing studs and rechecking them is time-consuming, but anyone with reasonable mechanical skills and proper tools can do this.

They should be good for many miles now.

I’ll post if I have any issues.

Your talking about your head studs turning 15deg.

When you torqued your head studs in steps, you may have missed a few studs on the final torque down or possibly not enough assembly lube to achieve the correct absolute torque value.

I installed Exotic head studs also and I did a retourq after a few heat cycles I barely got 15 deg on a couple and the rest were all on.

Are you all retorquing by simply putting your torque wrench on and tightening to spec?

The generally approved way is to loosen a stud one by one and bring it back up to spec.
