5mm headgasket
hello,
I need some confirmation :
I'm fitting a 5mm TRD headgasket . In workshop manual torque is set to
6,6Mkg . It's seems so low to me !

Can anyone confirm that ?If somebody has tried a higher torque , any advices and experiences welcome!

Those steel headgaskets usually have some pretty specific torque settings (higher than stock I believe).
You should look up TRD's specs if you can find them somewhere.. Maybe ask thomas (the Doctor) if he can take a peak in the TRD bible for you?

Maybe it's because the stock headgasket is already a metal one?

It need oe torque,
it´s if you use other headbolts,that it needs to be different,
If you take tha oe bolts to a higher torque , you will just stretch the bolts,


So oe torque, that´s what will work

I've finally set it to 7Mkg .hope it will last long....
As you said Ivan , I think that a metal gasket doesn't get as much distortion at tightening than a metal one .
Thanks for helping
