head bolt

about 10 days ago i placed a post asking about how to fix a head bolt that it stripped out of the cylider. i took it to a machine shop and they couldnt put a heli coil into it cause they would have to drill it out and they might damage the sleeve. is there any other way to put the head bolt back in? there is some threads left, not much though...some kinda of super adhesive? liquid metal or something?
we have a tonne of snow and i have nothing to ride, so someone help please.

Re: head bolt

Sorry,I can't think of any adhesive or filler that would hold up. I think you should take it somewhere else for a second opinion. I wouldn't think the head studs would be so close to the bore that significant damage would be done by tapping to the next size for a helicoil, unless they have to go up several sizes to fit the helicoil. If so, then maybe going up only ONE size would be feasible.
You would have to make sure that the larger clearance hole in the head wouldn't be a problem, and you may have to modify the head of the bolt(or the nut on the stud) to fit it in a recess in the head if there is one, but that might save you.

Re: head bolt

Another option might be to retap that hole to the next larger metric or standard as the case may be.That has worked in the past when there is not a helicoil option available,like saturday night right before that big ride with your buds.Just an idea hope you get it fixed!
