My solution for cummins heater bolt failure

My friends 6.7 just failed from the heater bolt at 150k miles, head is off going to a machine shop but thankfully block is fine.

Made me immediately dive into my 6.7 with 300k miles for some preventative maintenance and a valve lash while I'm at it.

My understanding is they fail not directly because the nut backs off and falls into the engine, but because the nut backs off enough so that it arcs and melts the stud right off, my idea was to just lightly tig the nut, strap and stud together so it can't lose contact, I tried to be as quick as possible not to damage the insulator.

I don't see anything wrong with it, but we'll see if mine bites the dust soon lol.
