Re: Re-tourqeing Headbolts?
I know I checked mine before I tore it down for head gaskets, and I would have expected something closer to 180, but they were closer to 115. You can certainly try and re-torque, but with TTY, there is no definitive spec, so anything you take them back up to is just a guess. For this very reason, if Cummins supplies a spec for re-torque, they are not TTY, but if there is no official re-torque spec, they may be, and then it would be up to some brave experimentors to try and find the failure point.
