I'm in the same boat. I have 1 thread left so cleaned everything with degreaser and used heaps of silicon rubber to hold things in place fir now. I'm shopping around fir a time sert system to repair the thread properly - am planning to do it without pulling the engine apart!

Set it and forget it ! When the timing is set you shouldn't have to do it any more. No need to keep pulling the inspection plug out.

I would remove the plug, clean the threads in the case and on the plug, coat both with a good oil resistant sealer and put the plug back in. Let the sealer set up and it's a good bet it won't leak or fall out.

Well it's two options really. First is to split the cases and re-tap the hole larger or put a helicoil in it. Second option is to try it with the cases still together .... Quite possible but you have to be bloody careful about getting swarf inside the engine (heaps of grease on the tap should do the trick). Then either helicoil or timesert it.
