who can remove 2 broken exhaust studs? $

[jackdg93]

It's on a bike, but I already have everything off so access is good.

If I can't find anyone to pay to do it for me I'll be giving it a bash with a drill, extractor and blow torch.

Near to Milton Keynes.

These guys travel out to do thread repairs and helicoils etc. Had a spark plug blow out on a V8. They came out, repaired with a wurth time-sert for £110 all in I believe. That was 4 or 5 years ago now, still fine, had a few plug changes since. Didn't have to pull the cyl head, all done in situ.

I'm sure they will do stud extraction too.

Are the studs still proud of the surface at all? If so, my preferred method is welding either a bolt or nut to the stud and using a spanner on it. The heat from the welding will help heat shock it too.

Theres like 1-2mm off of flush. Yes the weld method looks good but I don't have access or the skills to welding!

thanks for the suggestion of vintage engine, will give them a look

Just had a call with them, very helpful guys so thanks for the suggestion.

They will only work on it if I remove the head, they wont work on it in situ, which deflates my confidence in a DIY job! at least I know I have this option now.

I've taken countless cylinder heads to them for rebuilding without issue, and flywheel lightening

There is no real finesse when welding a nut to a stubborn stud. I would try getting a nut on there, just a few threads, then stick a welding torch down the middle of the nut and pull the trigger with fairly reckless abandon, let it cool and repeat, try get the weld halfway up the nuts threads at least, then bosh a spanner on it after some liberal gt85 / plus gas / gibbs lube over the area. I assume the cylinder head is alloy? I'd have my little 100 amp welder on max settings to boot, get some heat in there depending on proximity to the mating surface of the head.

You need a local travelling welder perhaps. I did have contacts for a guy who does diesel glow plug removal in situ for Mercedes and others but have lost it in a phone change a few months ago. He was in MK I think.

I'd do it, but I'm having flashbacks to the time I had to remove 4 snapped bolts in the differential of a Jaguar xj12 axle. I drilled it all out in situ and re-tapped it all over the course of 2 days, on my back, on a driveway in torrential rain, yeurgh. You're on your own!
