A point I'd like to make - a helicoil is, by no means, an indication of a problem. NASA regularly uses them in spacecraft (source: Nasa Tech Briefs) for new holes, because they give better fastener strength when going into softer materials. > Any information relating to this - or stories of similar disasters - > gratefully received. I'd have a hard time trying to hold any manufacturer liable for any defect on a 12 year old car, especially if you haven't had control of it the whole time (you haven't) and don't really know the history of it (you don't). Who is to say that, while *this* garage didn't overtighten it, maybe some previous garage did, which caused the helicoil to act improperly? No good suggestions, sorry. I think you're going to end up eating this one. Dave Hinz
