psychoSEAL Helicoils are good for a quick fix with a LOW torque setting for that bolt, under 50 lbs. in Aluminium. Any thing over I go with a timesert or Keenserts. They are a solid insert with a locking pin that pushes into the edge of the threads and keeps the insert from coming out of the hole when removing a bolt. You should use a touch of high strenght loc-tite (RED) to help with keeping the insert from twisting also. Timeserts come in a kit with drill bits, installers, flat surface face installers, and the correct tap. A master kit is about $300.00. Expensive yes, but you will only need to buy this kit once. I just replaced all the helicoils in my shelby heads because they keep loosening up after racing. I broke a heavyduty rocker shaft and ripped half the threads out of the head. Installed 8 new timeserts, no problem yet with rocker assemblies coming loose. Make sure you allow the loc-tite 24 hours to cure if you can. There is a little more work with timeserts. This is the only differents. You can repair the hole on the car as long as you can get a straight shot to the hole. If you go through the manifold into the water jacket, make sure you add pipedope to the threads on the bolt. The surface must be dry for it to work and last. Rick L. Ps.
