Jammed spark plug- need help asap

i have an 89 civic hb and i was going to change my spak plugs and ran into a huge problem. in chamber 3 the spark plug was jammed and i put excessive amounts of force only to end up having the spark plug break off. the weird thing is the whole spark plug came out except for the threads. any suggestions on how to get it out? this is my everyday car so i need help so i can get the car running again ASAP
-Thx

Oh dear, you might be lucky, but usually this will involve taking the Cylinder Head off and using a 'Tap & Die' set to remove the plug. Given that this is a Japanese engine, I think that's more than likely gonna be the case....Use some WD-40 next time!

Oh, and I'll move this

judging from the ugh! i guess you have the head that the plug go straight down throught the valve cover you might remove the valve cover and be able to get closer to the plug hole you said the threaded part of the plug is still in there so you maybe able to use an ez-out(most parts store's sell these just get the right size to fit inside the plugs threaded piece you also may want to soak the threads with a good penetrating oil or use some heat to warm up the threaded piece then use the ez-out if this dont work then its removeing the head for a heli-coil repair you could do this with it on but all the metal shaveings will go into the cylinder and you can't remove this(risk damage to cylinder/rings)

I took off the valve cover and it did not get me any closer.. only like 1/4 in. its a deep hole and the threads are pretty far down.. is an ez-out long enough?

also the threads are so tight they are like welded on it seems...took every last bit of strength to break the plug out thats why it seems almost impossible to get the threads out

the last time i seen this type of problem was an 87 grand am 3.0L the center plug broke at the threads because the cat plugged up overheated the manifolds and back cylinder head to get it out we pulled the motor as there was no room to work on it
with the ez-out you might have someone weld a nut on the end and be able to use a socket and extension to reach down as the ez-out is about 3-5 inches in lenght
if this doesn't work it pulling the head drill it out and use a heli-coil repair kit

you can actually buy ez-outs for spark plugs that have a 3/4 hex on the end... and if you're careful about shavings and coat the drill bit/tap/whatever you're using to create shavings with grease, then blow out the cylinder, you can do it on the car...

The only CORRECT way to fix this problem would include removing the head.

agreed... but sometimes optimum conditions cannot be met. just suggesting an alternative to the ideal method that i've used in a pinch...

Putting metal shavings in a cylinder is not really an option... the only way to avoid that happening is to remove the head.

Removing the head is DEFINATELY worth the time and effort. Rather take the extra time and have it done right the first time rather then take the quick/easy way and risk messing something up that will be more time consuming and also costly. Good luck with the problem.

guys the car is sixteen years old how much longer is it going to last before the frame splits/rots out how much mileage is on it if it was a rebuilt or a newer engine then yes alright pull the head have it fixed find some other problems while this is being done fix those were does it end maybe he'll break more bolt's in the block(exhaust/intake)or he'll spend the money then right it off you got to know when to put the money out for major repairs or just a band-aid

thats my thought's on this say what you want
