Spark plug repair inserts

Blew #7 spark plug out this weekend, threads and all, repaired it with an steel insert.
Next night #6 went that already had a steel insert but threads were still good. Added more loctite and screwed another insert in.
Is there something better to use than loctite? Seems the red can't take the heat.
Are the steel inserts okay for repairs or is it better to have them welded back up?
I run an old set of BAE fuel dual plug fuel heads. I run the steel plugs in the extra set. Thought about getting dual plug valve covers and adding the option to use a virgin hole. Still have to rely on the loctite to keep the steel plug in the hole not being used.
Both passes 39# of boost.

Any thoughts? Joey

 

what type of insert? Dave

 

14mm spark plug repair insert? Tap the head bigger, screw the steel insert in then screw in new plug. Idk, get em at the local parts store.

 

Loc-tite's grip is broken with too much heat.

 

get the timesert ones i have never had any problems same type of heads as you do order the kit comes with the inserts and the twostep tap works great and i have done several time with the heads on the car no problems

 

Thanks Jim,
Are you using the aluminum ones? Do you recall the part #?

 

yes timeserts, buy the kit..Dave
