Winter Chassis Re-fresh

[Kaz-kzukNA1]

Helicoil is good for this purpose and used it at several different section of our NSX.
Addition to the gbox, the mating bolt thread at the suspension control arm, curved/L-shaped holder bracket between the eng/gbox, etc all suffer from oxidation.
When removing the bolt, if you felt something not quite right, just mark it so that you can check and deal with it before re-assembly.

For Eng block, timesert is better but it requires extra meat to be removed during the preparation and the jig/die is quite expensive.

For other places, helicoil, v-coil or the likes are good enough.
Just make sure to check the material of the inserts and the required length for your purpose.
