Much gratitude!
a great way to break rusted bolts is too use a beaker bar. Use an impact instead. This guy is clearly not a mechanic.
How many of y'all broke your studs?
In Michigan, there is usually no lands left for a socket to fit on. Then the stud snaps off with the nut. I use a dramel tool with cut off wheel and I split the nut on one or both sides. I then use the appropriate sized thread tool to clean up the threads. Generally , you can do this one time only. After that, the stud will rust away to the point it cannot be cleaned up. I have been doing this method for years on everything from cars to snowmobiles and other engines where rust causes issues.
What you do when that head breaks?
What do you do when it snaps off?
The very first thing to undo when doing an engine change or a clutch, while the engine is still hot.
Die grinder. Cutoff wheel. New studs.

Thanks for your knowledge and tips…great vids
Nah, get the torch on it after wire-brushing …… no point in spraying lube on it because it will NEVER get ro the threads of the stud because of that very nut you're trying to get off!!!!! And be careful to heat the nut ONLY – not the stud, because if you do, then that's when you sheer it all off and then your problems REALLY begin!!!!
Starting-up and letting the car run will never produce enough heat to get that nut off – you need a quick blast with an oxy-acetylene torch on a small flame setting.

If you crap out the treads can you thread a new nut in?
I find Linkin Park and Limp Bizkit playing so loud that reception can hear help with rust.
This is how you do it on Kansas rust, maybe. On Minnesota rust, it's time to weld in a new flange.
I need to swap the cast exhaust manifold to a stainless one on my BMW 120d this weekend, the studs look rough on it, I have an induction heater, hopefully I don't snap any
I've found that using an impact with a swivel socket does not, in fact, help.
Well done, should help some folks. For me, move South to reduce the snow/winters and the lower structural / exhaust rust. After that you still end up with all of the same manufacturer – barely passed warranty — problems though.
I "saved" the boss's boat once by TIGHTENING the rounded bolt – and it broke free – then backed out
Mine broke, I drilled them right out and used a nut and bolt.
Love your tips. A lot of them are spot on.
next, buy lotto ticket lol
Break it loose, or break it
Screw all that, that bolt is trashed, I just use flaming wrench make it disappear, and put a new one in. If you are going to heat it and try to get it out or off, heat it up, then melt a crayon or candle and let it soak into the threads
Would a mini inductor work?
This will come in handy when I buy a car with an exhausssisem.
So… I took break it loose literally
Good point about wire brushing then off first.
sometimes the bolts are too far gone. The bolts holding my rusted cat together were so rusted on that I was physically twisting the bolt while trying to remove it. This was after leaving peno oil on it for three days mind you.
So how I doit is clean the threads then heat it up (via torch) and put a crayon on it. I know this sounds dumb but the crayon is your friend.
I recently used harbor freight stainless dental pick set to remove broken front wheel axle stub. Can anyone suggest a storage case for the set?
Rusted nuts are a bad thing
In my experience impact tools are better about removing rusted fasteners than a breaker bar without breaking the fastener. I think the vibrations loosen the rust
the trick is u did something that everyone knows sooooo….
But what if “hypothetically” the breaker bar, blowtorch, and PB blaster still isn’t enough?
Yep it does.cheers
cut and forget
Does penetrating oil actually work besides getting everything nasty and oily?
As we can see, pen oil is more like snake oil. The threads are still dry
None of this worked for me. Well i got 1 nut off. One nut broke loose but started spinning on the bolt not able to get it off all the way and the 3rd nut stripped and its at an angle to where i cant get a smaller size socket hammered on it. Any tips for my situation would be great. Thankyou
What if the bolt breaks on that type of set up exhaust? How do you install another bolt in? Mines came all off with the nut stuck
Lisle has a stud remover. Replace the whole thing.
Just did something similar and used a nut extractor after using penetrating oil. Worked like a charm. Also got a nut breaker if I have to remove it, that way no need to grind it.
The funny part, you have to do all this BEFORE EVEN ATTEMPTING TO REMOVE IT! Most novices wont' know it's seized until they round it off. So this advice does not matter at all. But it's a right to passage. Everyone has to deal with a rusted seized bolt when working on their vehicle.
