What do you do if you are changing your spark plugs in your car, and the spark plug breaks in half?

My husband was taking a spark plug out of a 96 Sunfire and it was in too tight. He tried to use a torque wrench to get it out, and it broke in half under the nut. There is barely any visable and is down about 2%26quot; in the spot where the spark plug goes. Please only legitimate answers if you can help!|||He still shoud be able to get it out. The ceramic is on the outside of the nut. He should be able to torque away now. He just needs to get his socket down over the plug as much as possible. Maybe spray some liquid wrench in there first as well.





-- sorry, I thought you meant the ceramic, but if the nut itself broke, and there%26#039;s nothing left to latch on to it%26#039;s much worse. These other guys are right.|||go buy a left handed drill bit, and a set of ez-outs. (ez-out is a brand name, and most hardware stores will know what you are talking about) drill the center of the spark plug out with a left handed drill bit about 3/16 diameter, then tap the ez-out into it. turn the ez out just like you would if it had a socket on it... it should come right out :)|||They usually break where the porcelain meets the hex. If it broke further dowm than that, you%26#039;ve really got a problem. You may can use an easy-out to get the balance of it out, but there will be parts of it down in the cylinder. A small vacuum and a magnet may or may not get all the junk out, but you may be looking at pulling the cylinder head.





If the hex is still there, (if a socket fit on it) use some penetrating oil and unscrew what is left of the plug, chase the treads out wiyh a tool, and put in a new plug.|||ez outs|||dont mess around with an ez out or anything like that. you will do more damage then good. if you can remove the head your self then take it to a michene shop thay have all of the right tools to fix it. this happend to me at work the other day. then when you put new plugs in use so anti- seez on the plug threds and only torque them down a little bit that will prevent this problem in the future|||Josh is pretty much right. be prepared to spend a bit of money. To prevent further damage, the head must come off to remove the plug and repair the galled threads which caused the problem. You should be able to drive without damage but it will run like c**p. In the future, use an anti seize compound on the threads to make removal easier. Also if this happens again stop as soon as the plug starts to get harder to turn. let it cool a bit and use plenty of penetrating oil to slowly work it back and fourth until it comes out. good luck.|||next time put what is called anti seeze is helps stop this kinda problem. hopfully you well only need to tap it out with a tap and die set it is pretty simple you drill a hole in the spark plug then you use a peice called a tap and you put the drill in reverse and hope the rest of the spark plug comes out. i am not sure but you might want to spray some w/d 40 in there to to keep it from seizing up any more along the way of coming out.|||tell your husband to get a easy out and try to get the broken piece out.if he ruins the threads get a heli coil and put a new plug in it.
