stripped threads on f22 head, repairable?

[eriemoto.]

the stud on the exhaust side, closest to the water neck will no longer torque because the threads are stripped in the head. is this repairable with a heli-coil or any other thread repair methods?

thanks

You will need to re thread probably with a larger stud

heli coil f.t.m.f.w.!!

should i try re-threading w/ a larger stud first, or go for the heli-coil?

Try running a bigger size tap in there and then using a different size bolt.

alright. so a bolt is ok, or should i run a stud still?

[wed3k]

id helicoil it just to be safe. after that you can still run the stud.

is there a torque spec for the manifold studs?

anyone know?

anyways, i heli-coiled the stripped threads and it worked mint. torqued down nice and tight, didn't take much to tap either
