Cast Iron Exhaust Manifold Broken Bolt and Stud Removal and Bolt Hole Thread Repair With Lock-N-Stitch Full-Torq Thread Repair Inserts

Here’s some pics of a cast iron exhaust manifold that came in for broken bolt removal and bolt hole thread repair. Someone tried drilling two of the broken bolts out and got way off center. We first removed the broken bolts or studs and then re-located the center of the bolt holes. We then machined the oblong holes for Lock-N-Stitch Full-Torq thread repair inserts. The two broken studs that weren’t messed with we were able to remove without damaging the threads.
