locktite makes a epoxy type repair kit for stripped threads, and it will hold way more torque than that screw will ever need.

 

The reason these threads strip is becasue of the disimilar metals and the chemical properties (steel and cast aluminum) corrode differenly when moisture is present. Plus, since the diameter and pitch of the threads are so small that makes it much harder to salvage the threads when corrosion starts.

Bryan hit the nail on the head SILICONE or RTV. The timing cover is non funtional in the sense that is not retaining any fluid nor does it hold anything of weight in place.

As Bryan stated put a dab of silicone/RTV in the hole thread or push the screw in there ans fudgettabout it....

Oh! put some Anti-Seize on the other 4 screws or you will be doing the same later on.

Thanks much guy's. I did the clear silicone seeing as the other 4 screws are holding tight. I will need to get some anti-seize today for the others. The threads were definitely on their way to being stripped before I removed the screw. Seems like they stopped tightening the screw right before it would start to spin and completely strip the threads.
