do you have to re-torque an AU headgaket? someone told me that because it's metal you have to re-torque it after 200kms or something..

I'm sure you guys would have mentioned that to me before if that was true..

not after it has been driven

usllay it is torqued down to a specific torque then the bolts are tunred a furth 90 or 45 degrees

don not re-torque the head bolts!
they are tty so no re-torque required, the old school stuff needed it.
