JB weld to fix threads?

[Nick_S]

So the PO had stripped out a few of the threads that hold the valve cover down. It doesn't leak but it does bother me. I know I could helicoil or something along those lines. However, since this isn't a part that regularly comes off and isn't subject to loads of torque to keep it tight, a mechanic friend of mine suggested you can use JB weld and then let the JB weld harden around it and it basically restores the threads? it apparently even says on the packaging but I haven't looked.

Anyone ever heard of this or done this?
Thanks
Nick

I dont know but I plan on testing its strenght very soon on my broken transfer case mount

A Helicoil or Timesert would be best fix. But JBweld may work in this application.

I've used an epoxy thread repair product similar to this for something like this, it worked fine, but I never really "tested" it once I did the repair.

What engine do you have? If M20 you could change the stud.

[Nick_S]

Sorry, should have mention. M42. Which baffles me how they overtightened it to the point of sheering threads. They have a stop where you can't turn them any further, once you're there stop! Think I'll try the actual epoxy thread repair that Rigmaster posted.

It should hold fine, but the next time you remove it, it may damage them again and you will have to "fix" it again. Helicoil will fix it forever and actually be better/stronger then stock since it gives you steel threads, not aluminum.

Helicoil is your best bet.

When you hit the stop, you just keep turning. It's easy. Just ask the PO of my 318...
