91 previa 2wd broken spark plug

[Biggee4x4]

Ok I just bought a 91 previa and the guy sold it because number 3 spark plug broke off in the head and he broke 3 ez outs and the 3rd one is stuck in the hole. The spark plug tube is giving me the most problem and want to take it out but not sure if I can buy a new one or where to get it? I don't want to mess it up because I am not sure if they are replaceable ? If anyone knows of any good ideas to try and get the ez out taken out please let me know thanks! I realy don't want to pull the motor and tear it apart if I don't have to thank you.

This may not work in your situation or be a bad idea .However I put a dab of jb weld on the end of
a old socket extension and got a broken socket out of a spark plug tube once. I let it dry for 24 hours
and used the original jb weld , not jb quick .From what your post said you may end up at a machine shop .
Hope not .
