Stripped Intake Manifold Bolt

[George C.]

Should I use a helicoil or time sert to fix a intake manifold bolt with weak threads?

Also, Loctite make a two part epoxy to fix stripped threads.

Are you talking about an intake manifold bolt hole in one of the cylinder heads? If so, if it were one of the blind-tapped holes, I think I'd use a Helicoil. If it's one of the through-holes, I'd probably use a time sert. However, I think that either type of repair would actually be OK for either type of hole.

As far as the Locktite product, I've tried it and I didn't like it. I could not get it to hold even modest torque (i.e 20-30 lb/ft). I'd be very interested in hearing the experience that others have had using it, though. Maybe I did something wrong. If it works good, it would be a great way to solve stripped thread problems. That's why I tried it in the first place.
