On a car I'm doing a few bits on, there are two studs from the cat/downpipe to the exhaust.

Of course, both have snapped whilst trying to be undone, and the usual easy-outs etc have done nothing to assist their removal. There isn't really enough thread to turn one nut against the other, so I'd imagine I'll have to resort to application of heat.

What's the best way to go about this? Heat the area around the stud, heat the stud itself, heat everything just to try and free it up?

Bloody nightmare, as both studs properly tight, and have proved to be fun to remove so far!

 

if ther is a bit sticking out weld a nut on it and just turn it

 

What have i told you about attempting things out of your league......



















Stick to making the Tea

 

drill it out...

Easy-outs are a waste of time on anything thats snapped off undoing. Doing up is a different matter but most people don't realise this.

Heat might work - but you need oxy-accetalene heat not a blow torch - bright orange should do it!

You may well have had a point Rob, had I not burnt myself on the kettle earlier

 

 

pon what about the "release spray" that freezes and everyone swears by these days

 

Don't know anything about them mate.... what's the score with them?

 

agreed. welding a nut as suggested has a similar effect to heating with gas torch, but is in many ways safer, sometimes easier and more readily available.

whatever method you use, when it comes to undoing difficult things (not just bra straps singlehanded ), always tighten a little first and work the extraction with a tighten/untighten action

 

they suck.... thats the score LOL

Good for fitting bearings - poor for siezed bolts/nuts/studs!

drill works, or them tools that "dig into" the nut then you can turn it.

you should have heated them to cherry red before you snapped them

 

Thanks Tony

 

no worries pon, don't give up your day time job lol

 

It's fine by me - will get done at no cost apart from time.

Rather that than pay a garage by the hour to sort it....

 

I snapped a stud when I fitted my PD manifold kin nightmare hope you get it sorted sharpish drill n tap
