Stripped thread on manifold - The 1947 - Present Chevrolet & GMC Truck Message Board Network

skokie · 11-24-2003, 01:25 AM

Ok I wrenched a little to hard

. I need to know the best way to deal with a totally striped thread on my manifold. This is the one that holds down the distributor. It is a edelbrock manifold. Any thoughts?

Thanks

tap it and put in a bigger bolt? or use one of those heli coil things

Not sure if either will work, as I don't know what bolt you are referring to...

(I haven't seen my truck in ages.

Helicoil probably better, don't know if there's enough room for a bigger bolt head there.

Get some steel epoxy and then get a stud the right size . Coat stud and hole with epoxy. Insert. Let cure. Use nut on stud to hold clamp--back in business.

Measure one of the other bolts and measure the thickness of the manifold and do some math.

Helicoil is the way to go. You'll have stronger threads than when the manifold was new. If you get the Helicoil kit,it usually includes a tap, helicoils and an installation tool. This is a permanent fix. You will need a 3/8-16 size. If you need a drill bit, it requires a 25/64"

Ok will check them out. BTW does anyone have a part number for the kit I will need?

Thanks

I have no clue how deep to re thread it. I would just measure the existing bolt and go from there.

yep helicoil is you best bet. Sometimes they are better than the original threads....

cableguy0 · 11-24-2003, 01:23 PM

in aluminum heli coils are about 100 times stronger than the threads being cut into the aluminum itself heli coil it and be done

Ok I just talked to Heli Coil. They are looking for a kit for this hold down. Just waiting for a call back. These guys are good.

Ok update time:
I have spoken to Heli Coil and I have purchased a 7/16 kit for this. Should be here in 2 days since the retailer is local to me. I will update the thread once I have installed it. Hope it works. I like my distributor to stay in place.
