How to repair a stripped sparkplug repair?

[decableguy2000]

Have a 359 on my bench that looks like a "Save-A-Thread" installed once before. Went to change the plug and insert came out with the plug.

Put a new helicoil in it. Or timesert brand is the best for a solid insert.

Time serts are awesome. However I can by a new cylinder for the cost of the sparkplug kit.

Having it welded is my go to , inserts and heli coils might? Work but welding is going to work period.
If you can get a cheap cylinder though ( sub 75.00) then thats a fix also.

Getting it welded or a replacement cylinder are the best options but should be the same thread as a Triton motor maybe an automotive shop near by has a good repair kit. The inserts that come with the good repair kits are much better than the cheap $25 kits you get at AutoZone and usually the Ford repair is expensive due to labor shouldn't take long to do chainsaw cylinder.

I had one that came out and whoever did the repair didn't flare the end, I put some locktite on it and used the tool had to flare it.

You can also rent the insert tool from O'Reilly, I did a friend's v10 once.

If the insert backed out on the plug you can install a new one. Loctite and stake it well.

I would put one of those inserts for the fords in it with some loctite and run it

Just won a "Vintage Heli-Coil" on E-bay, should cover my needs for the rest of my life time. About as much as a decent aftermarket cylinder kit.

Heli coil makes a solid one piece insert that is 3/4” NF on the OD. Hi temp red loctite and good to go. I may even have some more at work if you’d like me to check.
