WHATs THE BEST WAY TO FIX A STRIPPED DRAIN PLUG?
Some guys have had success with a helicoil, but many of the cheap, plastic ones won’t follow the new threads (keep skipping to the next one), and the steel ones are expensive ($30 or more). Another solution is to get a Timesert kit that installs a permanent steel “nut” in the aluminum case for the drain plug to screw into. But Heli-Coils and Timeserts prevent the oil from draining from the little horizontal hole that runs into the main 10mm hole. You could tap the hole out to 12mm, and make a new plug from a 12mm bolt, but here’s a similar solution that keeps the hole at 10mm… The stock drain plug is about 1/2 inch long, but the length of the hole in the case is about 1 inch, so you’ve got maybe 3/8 inch or so of good metal left above the stripped threads, and part of that is already threaded. Get a 10mm x 1.5 tap, run it up through the threads that remain and cut new threads at the top of the hole. Be careful — the aluminum in the case is very soft! Next, get a new 10mm x 1.5 bolt
