Subject:Re: WBX Cylinder Head Nut Torque check, re-torque

In practice the sealant will not completely prevent a re-torque. Using the beam or gauge wrench apply for up to the 41 ft. Lb. The loose nuts will be obvious and you can only make this better. If a nut continues to turn and you feel like the stud is stretching than stop.

For best assembly when doing a head install I clean the threads on both stud and nuts with quality tap and die. I lubricate the stud threads with copper based anti seize and make sure the sea at is only on the flange. I also learned like the picture 518 here but that rules out future quick re-torque. The "Right Stuff" is not a good choice here. I have also used the 518 on the cylinder top gaskets with success.

Dennis,
From my phone.

Subject: WBX Cylinder Head Nut Torque check, re-torque

Hi all

I'm searching but don't see a clear direction on this.
For checking, re-torquing WBX head nuts (I think it's the first one):

- in Bentley torque sequence, check torque of each nut, re-torque as
needed?  Or,

- drain coolant, remove - install each nut one at at time in reverse order,
apply new sealant at each nut?

Thanks

Neil.
