Enginetech "Time Sert" and "Big Sert" thread repair kits solve the problem one and for all. They utilize solid bushing inserts that are easy to install and will accept and maintain as much or more torque as the original threaded hole. The solid bushing inserts mechanically lock into place to prevent backing out and also provide a leak proof thread repair. Installation of the Enginetech's solid type bushing is an easy process. In most cases all you have to do is drill out the affected hole, counter bore, tap and install the bushing.The "timed" thread design of Enginetech's thread repair inserts makes them the thinnest solid bushing on the market and allows them to be installed anywhere a coiled insert can be used. Many specialty repairs cannot be performed with a coiled wire type of insert. Thread repair of crankshaft "snouts" are risky because of the high torque load and vibration, but Enginetech's solid inserts work every time.
