Snapped exhaust stud :(

[punkture]

What's some good ways to remove them from a 3s head? I have no oxy acetyl

[thechuckster]

can you mig-weld a bolt onto the broken bit?

[mattysshop]

broken internally or flat with the head? just gradually build up the stud with small bursts of MIG, just enough to get some vice grips on there... plus the focused heat will help also...

don't worry about 'welding' up the hole... steel doesn't weld to ally

might i suggest while your in the area just replace all the studs and nuts with new ones.. for the sake of $10 of fastners at your local bolt shop (don't be silly and go get 'handy packs' from supercheap) it will make life alot easier!

Unfortunately don't have access to a mig, I'll ask my oldman if he can get access to one perhaps, so I won't have to drill it?

...so I won't have to drill it...

EZout's are not easy, don't drill it!!!
A 8-10mm stud just busted and something about half its size cannot move it & will break too unless the hold between stud & head has been loosened up. Then even if loosened with heat, the wedge action using the extractor will jam the stud into the head.
Good luck.

After a fair hunt, I think getting a mig to weld a nut on seems the go, should i hit a nut and bolt place for the stud or?

[thechuckster]

may as well if you are out and about. While shopping, buy a small tub of anti-seize grease and smear a bit on the studs when re-installing them. Most of it will get burnt off by the heat but it'll stop this kind of shenanigans occurring again.

^^^ This. I use antisieze almost everywhere thread lock is not needed (wheel studs, external engine bolts, exhaust, bracketry, brakes, etc etc.) and the days of snapped bolts has ended for me. Torque settings are more accurate and bolts don't stick. They won't come out by themselves either if they are torqued correctly.

I use the Loctite stuff in a small glue stick type pack. It's about $15 a stick and is rated to 1200 degrees C or something. Use it on any bolt that gets hot and you'll be laughing the next time it has to come apart.

Legend! I think Matty shop is sending me some new studs I'll loctite her up good would the standard studs still be okay or change them
While I can? I have 2 sets of standard studs

[TERRA Operative]

Standard bolts will be fine, as long as they're new and shiny, and not old, fatigued and rusty.

[thechuckster]

I'll loctite her up good

note: you only need a small amount of antisieze on bolts

[punkture]

... There goes my parts washing idea terra the bolts are still in head and presumably old and rusted.

Replacing old bolts is cheap, removing broken ones is not.
I'd replace them while you have the chance. If you've broken one already.........

Just take it slow when pulling the old ones out, give the thread a clean with a tap and some compressed air, then a wipe of anti-sieze on the new bolt and torque it in.

Otherwise, if you can't replace them for whatever reason, give the existing studs a run over with a die, then a good wire brush followed by a lick of anti-seize. Use new nuts (I use high tensile flange nuts for bolting the extractors to the head, normal high tensile nuts, washers and spring washers everywhere else) and it should be sweet.

Found out my spare head has stainless steel studs, definately winning there haha

[mattysshop]
