need help w/ a broken header bolt!!!!!!!!!!

Yes I broke off a header bolt.. Then I broke off the EZ out.?*#!!

My drill bit does not want to drill through the EZ out. any ideas?

 

weld a nut onto it. Pour the heat into it, hwich will help loosen the bolt. Use a washer or two to keep from welding the nut to your head (this is a cast iron head right?)
You'll probably break a few nuts off, just keep at it, it'll come out.

 

the ez nut is recessed in about an 8th inch.
I don't see welding a nut on it maybe a bolt?.

 

anyone?

 

Get a 1/4" wide chisel and hammer and put on some safety gl***es!
Chips WILL fly!
Hit the bolt/EZout as if you were marking a clock hand on it clockwise, in the direction that will tighten, and loosen it in the threads.
As soon as it moves some chisel on it in the other direction and it will back out as you chase it with the chisel.

 

Warming it up with a torch and applying some candle wax to the thread area will help in the removal process.

 

fire up the MIG welder... weld a 7/16'th nut to the broken bolt / easy out. you may have to do this more than once or twice, but keep trying.. it will work.. weld thru the nut onto the bolt. do not worry about the weld sticking to the head, it is not clean enough to stick..
let the weld cool a minute or so before you try turning the nut.
be patient, it will work ! saved my tail many times using this method.

Last resort but sure fix , remove the head and have the bolt laser cut out .
Years ago , I did the same thing changing a intake. I ended up pulling the head and had the bolt laser cut out. Try everything eles first .
Snap off a EZ out then you are almost always done.

 

See if you can chisel out most of the ez-out remnants if not try a machine shop or a tooling supply for some better bits it may take several of them but you can get the rest out if you are patient.
Drill the hole about 1/4 in deep with a 3/16 bit and heat up the broken bolt. Throw every ez-out you have in the garbage or give them to a neighbor you don't like. After heat beat apropriate size torx head 3/8 drive into the hole as deep as i will go. You want the torx to be slightly larger than the 3/16 hole. Give her a little more heat and turn it out. It has never failed me yet. An old mechanic showed me this method when I was 15 or so and I have never used an ez-out since. I don't recall a bolt I have not got out yet. Not to say anyone elses advice is not good but I think if you start welding on it the head is going to come off and go to the machine shop. Good luck and be patient.

 

Way back when I was an apprentice we had to remove broken 3/8-16 taps from $100,000 jet engine parts by grinding a hole through the center with a Dumore grinder (Dremel would work) using a diamond bit. Once you got the hole through then you would open it up until you had four pieces of the tap. (four flute tap) Then just pick them out with needle nose pliers. Took several hours but so what? Teaches you patience. If you choose to chisel and punch it out hold a rag over it when using compressed air to protect your eyes.

 

Thank you for all your help!!!!!
This is why I love the HAMB!!

 

Welding a nut to it will almost always work. It will def take you more than once. After you weld the piss out of it, flash cool it with some water. The bolt will cool faster than the head/threads and that will help you a bit. I like to cool it with PB Blaster, kills two birds w/ one bullet.

It won't hurt the head wither, I do this all the time at work and haven't had an issue yet. I even did all 6 on one side of an SBC this way because the bolt heads had all rotted away.

 

heres what i do when i have a bolt broke off, sence your bolt is down in the head a little id start by welding on the end to bring it up to almost flush, then i would take a 4 " piece of 1"x1/8" flat bar and drill a 3/8" hole near one end, i`d take the flat bar and place the hole over the bolt and plug weld it onto the bolt, let it cool right down on its own, now you have a handle to start wiggling back and forth, back and forth, put some wd or whatever you have and take your time, if it snaps off just weld it back on, i find nuts just to deep to get a good weld on, the flat bar lets me get a nice wide plug weld on it. i hate easy outs and never use them, if you use the square kind they have to be hammered in to take a good bite and then you have expanded the bolt making it even tighter, if you use the screw type they expand the bolt to.

 

Find an old boilermaker and ask him if he will blow it out with a cutting torch. Not for beginners or weak of heart. Easy outs are misnamed but you've figured that out.
