Exhaust stud

[Skudd]

Yes it snapped, still has some thread showing. Tried the two nut method but the nuts are just starting to strip the thread so have stopped before it gets too bad.
No I haven't got a tig/mig welder like everybody seems to have when giving advice on welding nuts on.

Any ideas? Don't want to start drilling really as that can lead to all sorts of issues.

Worth a try plusgas overnight then try molegrips. Also heat the stud up with a blowtorch and molegrips again. Be carefully with blowtorch near ally or else up might end up with a puddle of ally.

Only thing is to bite the bullet.

Cut flush and drill it out.

Use a Masonry Bit with the Carbide tips sharpened to a cutting edge. They do not have a cutting edge as they are percussion cutters.

The carbide will melt the stud like a candle.

Slow speed and feed and some engine oil as a lube.

When you get it wallowed out to 'near' the root of the stud thread then you can pick the remains out.

The threads will relax a bit when you remove the meat from the inside.

Don't drill it. Been there, fucked a head good for n quick. Welding is the best option..I know you said it

Anyone near you with one you could borrow? Alternatively now may be the time to invest in one. Be prepared to let it sit for months on end without use...but when you do need it, it's worth its weight

Invest in one of these

Gets em out every time so long as there's a bit still sticking out. You can even lob the windy gun on the end and have it out in a jiffy.

Alum is an easy safe way to remove steel from an aluminium part. The only downside it takes a day or two, its not the quickest.


The drill chuck extractor above is a useless pos. Does not work below 8mm and then its still shit. Did not work for me. If you want to remove like this get an ER32 collet which will grip much better.

It is one bastard of a job I am not looking forward to doing since mine is blowing where headers meet the block.

Snapped studs are a cunt.

OP, I know that you've dismissed the two most practical methods of removal but I'm going to suggest them anyway. As you have some thread remaining, both methods should be a POP.

(1) Welding a nut on is a no-brainer and would be my first choice (I don't own a welder and doubt my competence using one but whenever I've presented a miniscule job such as yours to a professional, I haven't been charged as it takes them only moments to carry out).

(2) Drilling out a stud isn't difficult and should not be feared. All that you need to remove almost any type of broken exhaust stud, whatever the condition, is a good quality sharp drill bit and a broken stud drillerouterer. They're easy enough to fabricate and are also available to purchase:-

They're inexpensive and so easy to use. Every budding mechanic should own a set.
