I repaired this plug 2-3 years ago. I didnt use a helicoil or timesert. I used one of the thread savers that you flare the end so it doesnt drop onto piston. yeah I know im an idiot...
I never did loctite on the threads because I couldnt get the damn thing to thread in by itself, aka I got tired of trying.
So does anyone know if a helicoil is slightly larger than these stupid inserts?
Is there an overage option for dummies with a repaired one blown out again?
You can see the heads threads sitting in the inserts threads grrrr
