Not trying to hijack the thread, but I've heard bad things about helicoils and am looking for other options for fixing sheared bolts (as there are 4 sheard exhaust bolts on my 850). I've seen other kits that would work, but they are really spendy!!! I also saw in another thread that someone drills, taps and locktights an alluminum rod into the old hole then taps it to replace the old hole.
This got me wondering if a person could drill the old bolt out, tap the hole (to create a jagged surface along the length of the hole), inject some sort of epoxy into the hole, and place a stud (of the correct size and projection) into the epoxy using the connection peice as a guide for proper placement of the stud. Has anyone tried anything like this? I found an epoxy called quicksteel that says it could be tapped also, so that could possibly be an option of using bolts instead of a fixed stud with a nut. I'm just not sure about the expansion/contraction of the block compared to they epoxy, if that could be a problem.
Just looking for some wisdom on the matter.Last edited by Guest; 04-21-2008, 01:32 PM.

The consensus seems to be that Time Sert is a better choice than heli coil. I wound up not having to use either because once I got the cover off there was enough of a nub to weld a nut onto both of them and get them out. We'll find out about the header bolts in a few weeks when I do the exhaust.
