Drilled out the bolts on my front head because they broke off. put a puller in and it broke off in there as well. So Now I'm at a loss... I can't grab the puller to get it out, so what now??

 

[Lightwield]

If I end up having to pull the head, do I have to pull the whole engine to do so?

Are you referring to the exhaust bolts?

Bolt extractor?

If the answers to the questions above are "yes" then here is what I did (I could not drill the broken extractor leftovers with any drill bit):

1. Locate Dremel with grind stone (cone shaped with diamater smaller than bolt hole)
2. Grind at the extractor (tip of cone directed towards bolt hole) until there is no visible trace of the leftover space age metal (stay clear of threads)

** If the answers to my questions above were "No" I hope somene could chime in and help.

Yeah, bolt extractor. I will have to stop by Wal-Mart to get the dremel. I've never done this before, so I am a bit frustrated. It doesn't help that I'm sick and my patience is running thinner.

Have You got a mig or buzz box welder?
Tack weld a piece of steel rod or old bolt to the broken off bolt, only if there is some protrusion.
An acetylene torch will work as well, but one must be careful when using the torch.

 

[Lightwield]

Gonna try the dremel bit and the drill it out the rest of the way and use a helicoil to re-thread it... I hope

You can also get yourself a carbide drill bit and drill through the extractor.
It will require a steady hand and paitence.

 

[Lightwield]

I read that they would break if you are drilling on an edge.

I did the same thing, broke the hardened extractor off. Dremeled it flush, punched it and redrilled it with plenty of oil and a hardened drill bit. Small first, then larger and Viola, the broken extractor and the broken bolt just turned out.

Now I am very careful when using an extractor. First, use the correct drill size with oil. Second, do not twist, turn, or push sideways on the extractor. I make sure that I keep the extractor straight and the force directly inline with the broken bolt. The slightest side force will break the hardened extractor when under pressure.

I got too casual. It took a fair amount of time to fix the broken because I was hurrying and thought it would be easy.

See, I got in a hurry too. Now I am spending time and money to fix something so small...

Yes it can, you should start with a flat surface, if you use a dremmel or a die grinder you will need to have a carbide burr or a stone to flush the surface then you can use a fine tipped burr to make a "center divit" for the drill.
I would also tape up surrounding areas with blue painters tape covered by two layers or more of duct tape (duct tape is much harder to get off than masking tape) so when (not if) the burr slips it will minimize damage.
Post a couple pics if you can.

You really have not spent any money,,,yet.

If your next few steps are not perfect you WILL spend lots of money.

Did you apply heat to begin with?

Take it to a machine shop before this gets real serious.

You're not screwed,,,yet.

I like this idea,,,,, why take the chance of making it worse....

 

[MoDZuKi]

I have a carbide drill that would drill it.. but I'm not there.. look for a cobalt drill.
They will drill very tough stuff

If you can find a machine shop that has a portable Metal Arc Disintegrator, we used to burn broken taps out with it. Just another option.

 

[CDUBL]

Though my previous post provides a work around, I truly agree that a machine shop would be the best solution.

 

[Lightwield]

I bought a rescue bit. Should be here on Friday, along with my bolts and gaskets

 

[beezer]

I hope it goes well for you as I realize how crucial this is.

 

[Lightwield]

Got everything in now except for the rescue bit... This "tiny" project could have been completed yesterday, had I not used the bot extractor

Thats why I don't do anything. If you don't do anything you can't do anything wrong.
Don't put red locktite on it this time.
