Probably sounds obvious, but dont forget to make very sure your LPG/petrol lines are well protected from any heat source.

Petrol yup, good point will make sure its all clear.

Said car does not have LPG...... yet

Tunnie, I'm curious what happened , could you take tem out ?

Not going to attack this until at least this weekend, maybe longer 

Working two jobs at the moment, mega busy

ok.. good luck Tunnie   
 
 
 
ps: dont forget to tap it for some time..(before welding)

If you go down the electric welder route don't forget to disconnect the battery and just to be safe unplug
 the alternator

How about using a mole grip as well as a welded-on nut, if you have enough stud protruding. I sheared a wheel stud which had been put on with the ludicrous  torque beloved by those tyre places. I tried an extractor on it but was obviously going to snap it if I continued, so I used the leverage of both a mole wrench and the extactor at the same time, which worked. Make sure the grips are new or file the teeth sharp.

If you're 'just' going to try heat and welding a nut on.. have you thought about trying a set of roller stud extractors? (e.g. http://www.halfords.com/webapp/wcs/stores/servlet/product_storeId_10001_catalogId_10151_productId_530659_langId_-1_categoryId_165572 )

Assuming there's enough length to bite on, I've had some success with those.

I've got a set of extractors kindly offered to me & on their way 

So plan is plusgas + heat + extractor + praying 

Tony - Battery off 

Ewan - Hoping these extractors will do the job, never have much luck with mole grips

Tunnie, if you have enough thread left on them, your earlier idea from youtube using two nuts locked together on the broken stud is still worth trying first, although you will probably need a die to clean the thread where the bolt head sheared to get the nuts on. If you can do this, then I agree with Cem, give them a technical tap to help free up the stiction. Also remember that heating up the stud, and not quenching it, will anneal (soften) the metal of the exposed portion of stud. Ideally, you would heat the mounting and freeze the stud, as in engineering use for interference fits.

I'm full of unhelpful ideas like this, just contact me for more.

Good luck.

That's a very clear point that you have to remember... You want to heat the flange where the stud goes through and try to heat the stud as little as possible

Thanks gents

I have seen heat applied to studs which was then cooled by spraying wd40 so that it would be sucked into the gap between the face and the bolt.  It worked a treat, if you have enough stud left try that and then with a set of mole-grips try and get them out.

Tunnie, if you are not handy/experienced in welding, imo its better you ask for a close welder around you.. and bring him ..

Another good idea, ta. Will try that

Fatty admin would be the best, but I've seen his welding attempts   

Not that I could do any better mind!

Never use an extractor, if the bolt has not come out using the standard techniqies of heat, penetrant and grips etc then its stuck.

All an extractor will do is result in a broekn piece of hardened steel in the bolt!

Drill them out.
