I do NOT recommend this.

A forum member was explaining his method to me on the phone last month:
* Clean the shield (brake clean).
* A lag screw run in enough to catch.
* JB weld around the base of the screw - heat shield.
* Wait for it to fully cure.
* Close the hood.
* Crank the engine.

I have several serious concerns with this method:
* Glue entering the pre-chamber.
* Glue on the injector ring threads.
* Glue wicking = bonding between heat shield and the pre-chamber.
* The assembly explosively exiting the pre-chamber denting the hood, and if the hood is open doing great bodily harm or killing someone.

He now has a pair of unique dents in his hood.


Please be wise and consider safety before, during, and while cleaning up every repair.
Health & Safety


Have a great day.
