Spark Plug threads broke off in head

How do I get them out? I guess anti seize was not applied last time they were changed ,and by the looks of the plugs it was a long time ago

Basically I got all out, but 1 which broke. I dont want to tear the block apart so I heard of something called ezout?

good luck........ Ezout only works if you have a clear hole in it. If the hex broke off the spark plug then your going break the ezout. Sorry, I know its a pain, but the correct way is a head removal. You can try heating the threds and using a ezout, make shure all gasoline is gone and disconected!!!!!!!!!! The gas fumes explode!!!! Ive done that only once because I was pressed for time, I ened up taking the heads off any way and fixing it.

Well there is some of a clear hole it it, it broke off directly below the hex and took a good chunk of the ceramic with it, still a lot of ceramic in the hole though.
Im going to do all I can before taking the heads off thoguh, today it is raining, I sprayed some penetrating oil all over the hole and tommorow hopefully I will have some time to try and pull the plug out

If I can get the rest of the ceramic out of the metal ground, then I am sure the bolt can be taken out

Good News
I got it out, took a couple days of soaking in penetrating oil, and the 9/16th square thing from the socket set, not sure what its called but I took it and hammered it into the spark plug and cranked on it till it came out. all plugs changed, starts quick, and dosnt stall out.

I guess im lucky

extremly lucky. Now go buy a new 3/8 extension rod If I had 75 cents for ever time messed up a 3/8 extension rod I'd beable to buy new one Any way. Good to hear the good news. But did you apply some bearing grease and torqued them to 10 foot pounds? Bearing grease, anti seez, same thing.
