Exhaust Bolt Drilled Out Too Big

[Graemeb16]

Hi Guys, 

So I just picked up a 2005 290 as a bit of a project. So I just got to taking the top end out 

and the bolt that was in it was literally just hanging in there, It looks like someone had 

tried to drill out the old bolt and made a muck of it. has anyone ever had any success with 

using JB weld type product and a heli coil to fix this?

Thanks.

I'd get the hole alloy welded and redriil it

Timeserts may be more effective in this scenario.

I use time serts if poss or helicoils , I have all the sizes if you are local to Birmingham ?

Sweet guys thanks for the advice. I was hoping I could do it myself as a learning process. But sure I'll probably bring it to get it weldedm  Craig sorry man I'm in Dublin. But many thanks for the offer :)

Pics would help. 

I've used many helicoils and timeserts, but there has to be enough metal around the hole and, of course, clear access for a drill.

Stuff like JB weld and loctite thread repair are only good for temporary fixes and war times. 

The thing about timeserts, etc. is, you have a pilot hole. You don't have this if it's welded up unless your welder is very good and can center a carbon rod in the hole.
