okˇ¦ here's the picture of broken spark plug.
I accidentally over tighten the spark plug and it broke off in 2 nice pieces.
As you can see on the picture top one is normal plug and bottom one is what I got left.
The metal thread part is completely got stuck in the cylinder head and it seems like there's no way take it out.
Any new ideas how to take it out or how much does it cost me to take it out?
I used the screw driver to turn it(stupid move again) and I think small fine derbies has been fell off into the cylinder or maybe notˇ¦
Is there any way to take it out by looking at the picture?
AH~~~ I couldn't sleep last night and I was blaming me about my stupidityˇ¦
DAMN!!!!! It sucks

 

Geez!!!! First let me say that when your tightening plugs, they don't need to be tightened like lug nuts. If you don't have a torque wrench, just tighten them until you start to feel the plug tighten up and stop there. Give it a litter extra force and then stop again. The washers on the plug will keep them from vibrating loose.

You may have to have to tap into the remaining part of the plug with a tap and die kit to get it out of the block.

 

There are tools for such things. They’re called extractors or pipe extractors or something like that. Ask around don't go with the first mechanic you come across. Talk to shops that specialize in rebuilding engines. They must likely have seen things like this before.

Don’t mess with it or allow debris in the area.

GoodLuck,

 

Oh! damn...really?
I thought my only option is to remove the engine head or something...
is it possible to remove it like that?
because it's so tight and I'm afraid of debris might falling into the engine...damn.

 

I spoke to my brother. He's a mechanic. He suggested an engine rebuilding shop. And, don't mess with it!

 

damn!!!! does anyone know some good engine shop near Atlanta area???
or is there any other way????

 

There called Easy Out's. You have to drill a hole and thread them in. The thread is reverse on them so as you tighten the easy out up, it losenes the part thats stuck in and turns it out.

Any good machine shop or engine rebuilding place should be able to help you get that out. Hopefully without removing the head from you car.

 

There are tools that are intended for situations like this! I'm not sure of the appropriate name but the tool works like this... It is a reverse treaded, bolt like tool which you crank into a hole and as it tightens it will loosen the regular threaded part. I'll find out what it is and let you know. I also work with a guy who owns an engine machining company. He should know what to do. I'll have an answer for at this time tomorrow if needed!

 

If this happened to me I would take the valve cover off for more visability.. Then I would get a metal rod that is slightly small then the hole in the middle of the plug.. I would get a small o-ring and place it on the end of the rod (w/ glue) and let it dry.. I would then stick it into this hole.. I would then put JB weld down the hole using the o-ring to keep it out of the cylinder.. I would wait until dry and then twist the rod out.. I would then use a magnetic item grabber thing and stick it where my plug was.. This will allow you to grab the metal chucks from your screw driver event..

 

I think you're refering to the above mentioned "Easy Out".
Sickmen, I feel your pain. Good luck.

 

Dang! I'm overwhelmed by all your wonderful inputs and careˇ¦
I'm gonna ask around about the "easy out" and hopefully I get that broken spark thread out without dumping debris into the cylinder head or removing the engine head.
Thank you for all your awesome replies!
You guys are the BEST!!!!!
