A heli-coil is generally used for quick repairs. As far as strength goes, A "timesert" thread repair is top notch for aluminum. They are a thin wall design,with a shoulder on top for a good positive stop to ensure the thread repair will lock in and not follow on through the repaired hole into something it shouldn't. Keensert repairs are good too,but the 4 little tangs you drive in often damage the threads should you ever have to replace the insert. Just my .02 ---RED

Heli Coils the biggest problem is when you go to take the bolt out sometimes it backs the coil out and makes a bigger problem than you had in the first place, I have seen them come out with the bolt and then lock you in a place where you can't get the part off because it is at a certain angle, or the parts are connected to another.... I threw all the heli coils at work in the trash the left us in a bigger bind than we had to begin with....

IF ... the aluminum is thick enough behind it; YES.

Lock and stitch is pretty cool. Their web site has a bunch of repair examples, I thought this was a pretty extreme repair that most people would think the block was junk http://www.locknstitch.com/Repair%20pdf%20files/Custom%20truck%20with%20cracked%205.9%20block.pdf
