Broken spark plug

i need a bit of advice guys, ive broke a spark plug off in my engine!



I dont know if all spark plugs break the way this one has but i have been left with just the threaded part and electrode in the engine, the centre bit of the plug came out complete. So what im left with in the engine has a hole all the way through. Is there a way of getting this out with a stud extractor or anything else or is it a head off job? Also with the stud extractor, if i can use one would i get swarf drop down into the combustion chamber?

Youd struggle to get it off with head on without gettin shit in the cylinder. id get the head off and take it somewhere for it to be took out.

ooooooooh gutted, deff a head off job mate
