seems like the photos i had uploaded died so here is video!**


i have made threads and photos but recently had a friend drop off some heads that were pretty bad and showed in real time how i deal with them

pulled a ton of them in less than 20 minutes that he could not get out

just wanted to show people how it works again

Go one step farther and weld a nut on it and use a wrench to take it out. Also tapping it with a hammer will free the threads up some...sometimes.

But if you heat the bolt up before you try loosening it.....ive never broke one.

Cool info on it not messing up the heads. Good to know.

As for the nut, maybe if you got the goober long enough to stick out of the head, you could tack a nut on the end of the booger. That way you could get a socket on it instead of vice grips. Maybe that's what he meant. Either way, good info. A friend of mine had one break off the head of the bolt, still had about 1/2 inch of bolt sticking out. We heated the bolt with a propane torch and used vice grips. (No welder handy). Amazing how fast the head dissipates the heat. We had to heat it about 6 times. Each time the bolt would get tight again after about 30 seconds of turning.

if you can get on it with vice grips you can... do what you did, build it up then weld a nut on. i actually weld a washer on, then weld the nut to the washer.

It can be done but a TIG is better for that job. I've done it to the bolts on cast exhaust manifolds.

True. I got fed up with it after breaking 2 titanium drill bits in one side and a ez out on the other. Threw em on there and haven't had a problem yet. (Knock on wood)

Denmah,

Thanks for posting this up. I did the drill bit/ez-out thing last time, but that can go wrong quickly. Once a hardened bit breaks off inside the stud, you're done. I've got a 317 I'll be trying this on soon. Thanks again!
