Stripped exhaust manifold bolt hole
My truck started ticking again due to the manifold warping away from the head and its because the hole is now stripped apparently from with a cross threaded it. I used a thread chaser to fix the threads but it wasnt strong enough i guess. I know helicoils are supposed to bet the strongest fix but in a standard kit the helicoil is only 12 mm long and the bolts are longer than that. Is that still the best fix? Or would I be better going up a size to a m10 I wonder. Any input is appreciated thanks
And I didnt know which section would best fit this so mods move if im wrong
