"One final thought I have is install this whether there is a broken bolt or not as it will insure it won't break, basically it is reinforcing a common problem."
"Only works to eliminate exhasut leak ticks when the manifold bolt has been broken in the position mounted - doesn't address the many other causes of GM V8 ticks (carbon, lifters, etc)."
"Good luck getting a torque wrench in there. What I did was put my torque wrench in the vice, put my regular wrench up to it, and pushed at the same distance up the torque wrench handle as the regular wrench went. That allowed me to get a feel for how hard I needed to push on the regular wrench when tightening the bolts. It wasn't exact, but there was no way I could get a torque wrench up there."
"It does require some patience though, I worked from the top, bottom and removed the inter fender to get it installed.I thought it would be a 20 minute job but ended up taking close to 2 hour because there is not much room and my fingers are too big for the limited space between the engine and the firewall."
"The outer threads are stripped and the bolt sheared almost flat and is still buried in the head so removing the remainder of the bolt and installing a Helicoil would be very difficult, if not impossible, without pulling the head."
"This works for the right front and left rear broken exhaust manifold bolt."
"Put on as preventive measure due to past experience with the poor GM design."
