Stripped Thread Hole???
Hi, I accidentally stripped one of the thread hole for the base of the carb. The stud itself is fine. But I think the thread in the hole is pretty much stripped. Therefore, the corner of the stripped thread many not have enough tension to prevent vacuum leak.
Any easy way to fix the stripped thread hole besides replacing the whole intake manifold?
Thanks

I don't know how much of a wall there is around the stripped hole, but you could use a helicoil and use the same screw as you are using now.
Loc tite (I believe) makes a metal filled epoxy designed to fix stripped thread holes. Basically, you put the stiff in the hole, coat the screw with some lubricant, screw it in , and let the epoxy dry. I don't know what the temp allowance is on this stuff though. I found some of this at Home Depot.

Anyone has experience on either of those product? Pls, let me know.

Recoil inserts are made from high quality stainless steel wire, with a diamond shaped cross section, wound to the shape of a spring thread. The insert, which is larger in diameter than the tapped holes is compressed during installation then allowed go spring back, permanently anchoring the insert in the tapped hole.
Because of the larger diameter, the Recoil insert has a greater contact area and is normally stronger the original threads.

you then have a brand new stainless thread in your alloymanifold

yep, you will be able to use the original stud. the damages hole is oversized and retapped useing the tapp supplied. the hole is oversized to make way for the thickness of the Helicoil itself.
another, less preferred option is to drill the hole to the next oversize and retap the thread to take an oversize bolt.
most fastener stores will carry oversize fasteners.
(i can only talk from and aircraft repair point of view, where oversized fasteners are a regular occurance)
