any tips for getting a broken extractor piece out of my iron lt1 heads? this **** is impossible to drill out. it broke off in where the header bolts up on cylinder 8

 

what did you break off? If its a tap or an ez out it is too hard to drill into. The only option is to shatter it with a sharp, hardened punch and a swift blow with a hammer.

 

Are the heads still on the car?

And if you broke a screw extractor you're doing something wrong...

 

I have seen the cheap ones snap, but it still takes some doing.

 

Exactly.

 

luckily the motor is out of the car and on the stand. take it to a shop and have em drill it out with a press? and yes i broke off a piece of ex out in it trying to get a broken header bolt out

 

Post up a pic, Might be easier to give tips on how to get it out. Is it broken off flush with the head out a little in the head?...

 

its flush with the head. idk how to post pics.

 

you will have to try to shatter it. I have been through this before. I broke a tap off in my head before. Shatering it will be the only way because the hardness of the steel. You dont need to necessarily hit it hard, just a quick hit with a sharp punch.

Here is a pic of my dilemma, fixed it by shattering the tap. Its really a common thing people do to remove a tap. (I tried a tap remover btw)

 

after:

 

YES!

A broken screw extractor can indeed be drilled out, just not with an "all purpose" (i.e. - wood, plastic, and metal) drill bit.

You must use a new, sharp, metal-specific (i.e. - 150 degree angle tip) drill bit.

(Ask me how I know)

Good luck!

: )

 

i tried that for almost an hour and got nowhere with a brand new drill bit made for steel. should i heat it up?

 

If your good with a welder ..put a nut on the end of the extractor and plug weld it then use a socket to turn it out.....

 

The head? Yes.
The bit? No.

You may need to sharpen that (now one hour old) bit as well.

 

i figured that heating the broken ez out would weaken it and make it easier to drill out

 

do you have any pictures of it at all?? i will post it for you in a few minutes
