Aluminium Epoxy?

It's hard to tell from the picture, but I assume the crack is all the way through to the threaded hole into which the bracket bolt is fitted?

If so action of the bolt tightening will force crack gap larger, so I doubt any metal glue will cope with this. I have used magic metal myself successfully, but it's not for this job in my humble opinion.

So possible options:-
1)I good welder should be able to get a tig in and make a seam repair. Not one for a DIY'er in my opinion, but a possibility.
2) Put a smaller (clearance) longer bolt through the hole and use penny washers and a nylock nut on the other side and pinch it all up. This removes the opening action of the current bolt in the threaded hole, you have replaced it with a pinch action nut / bolt over the metal.
3) live with it, it's probably been like that for a while.

Hope you can visualise my poor description for option 2 :laugh: If it was mine I would try opinion 2.

It's probably cracked because it's been overtightened in the past, or the threads have "picked-up" or it's all cross threaded, ultimately applying too much pressure on the assembly and piping the crack to alleviate.

Riccy beat me to it, but it's the same solution so it must be good, two votes.

Thats the engine block....weld it easy enough to get to.

Thanks for your input all sounds good to me not attempted to loosen the bolt yet damn ham fisted mechanics that have to over tighten things

Tha more I look round this Xar the more I seem to find wrong with it I appreciate its had a hard 14 years judging by the rust ,but I must say your options are feasible along with Riccy,s ideas so thanks again for your help
