On ea81 manifold one of the carb stud was the hardest to remove. after lots of wd40 and trying i got the stud but must have taken some of the thread wif it. With still some thread left in it i intalled the new bent studs for the holley and adapter plate. while tighening the nut drown on the stud it was kindof tight but then it stripped again. Is there any apoxies on you can that can glue the stud in? I have been driving it with the stripped thread and seems alrite. im gettin 350km to a tank, city driving beating my old hitachi by about 50km:brow: . And thats with me tuning it but i am gunna take it to a mech soon. Will 3 studs hold a holley downs sufficiently?

Over on this side of the Pacific, I would probably use a thread insert (aka Helicoil) to fix your problem. Pretty much a permanent fix. Can be pretty pricey for just doing one hole, as you have to pay for the tap and insert tool (been awhile but guess $20USD). Other people have done epoxy fixes, but they must be smarter or braver than I am. I am sure I would just bollux it up.

helicoil is a permanent fix if you intend to never remove that bolt again.
I use the more expensive "time-serts" which allow you to remove the bolt/stud many times over if needed.Good luck.

Bob,
You ask for an epoxy,
not a mechanical fastener
I believe?

The two part epoxy I trust is JB Weld.

The other good choice is a product by "Loctite"
Specifically named "Stud and bearing mount"

This is an anaerobic compound that cures only
in an area where ther is no oxygn present.

It will fill small gaps and hold the stud securely

Hope this helps

I will second that as an epoxy to use.

... helicoil is a permanent fix if you intend to never remove that bolt again.


I am confused... If his came from almost anyone else I would call BS!! How do you figure that you never could/should remove the fastener? I do it all of the time. Am I doing some ignorant russian roulette? :confused: Truly an honest Q, not a challenge...

I can't understand exactly what you're getting at with your typos,grammar,etc. Is this some kind of whack at me for suggesting a timesert?Sorry that I didn't suggest an epoxy.Timeserts blow away helicoils.Next?

Calm, please. No insult intended. I am too asocial to bother insulting people who deserve it, let alone someone who goes above and beyond to help others. You are amongst the people on USMB that I "listen" to carefully. Nothing but respect.

I have never heard of timeserts, so I have no knowledge or opinion about them. Perhaps they are not marketed on the US west coast? I don't know. But I would like to learn about them.

Loctite also has a porduct specifically for stripped threads, "Damaged Thread Repair", or something like that.

Has stuff for in the hole, and a release agent for on the stud/bolt/nut, which can be removed and re-torqued after allowing full cure.

And JB-Weld is good too, as Skip said.

Have used Heli-Coils in the past, but they can lock onto the bolt as well as the threads of the hole, making removal darn near impossible. Which is a good thing for a stud, I guess.

Never heard of Timeserts myself, either. Curious here on them..........
