I think it would be incredibly difficult to install a helicoil, or a solid insert, in an assembled engine, let along while installed in the car. There really is no room to get in there to do that work. It is more likely that your mechanic installed one of those quick and dirty repair studs, which has what look like oversized wood screw threads on one end. These can be easily installed in the car, are cheap, and guaranteed to let you down at an inconvenient moment. I have avoided even mentioning them for fear that someone would think that they amounted to anything more than a VERY temporary stopgap solution. If you have one or more of these, you should be shopping for a rebuild, and a real solution, right now! A helicoil, on the other hand is usually a very good repair. They are seldom used for head stud repairs, however, because it is difficult to keep oil from the case from leaking out through them. The solid inserts don't have this problem.
