I had my exhaust manifold gaskets changed prior to my last long trip. 200 miles into a 3500 mile trip my leak was back. (passenger side rear of manifold.)
My shop had over torqued the bolts and the last one as expected popped the head of the bolt off. The next one forward I wasn't so lucky, it pulled the threads from the head.
Here is my plan. Pull the manifold work out the broken bolt with vicegrips, then tap and Heli-Coil the one that was stripped. reinstall with new gasket and new grade 5 bolts then torque to factory spec. 22 ft. lbs.
Do you think the Heli-Coil will hold up in this application??
I have the room to work to do this and it's a lot better than pulling the head.
