Which one was it, if it was one of the front ones you might be able to use a stud removal tool, one which grips the stud tighter as you undo it (though I cant remember how much room there is for this). Another way is to weld a nut on top of the bit that is sticking out then use a socket to undo it.
If its one of the rear ones then you might have some faffing about removing all the gubbins that hides them first.
Either way it might be an idea to let some WD40 soak into it for a while.
Hope this helps.

Mike, Half the time the reason why glowplugs and sparkplugs snap off is due to someone putting them in so tightly - I recently serviced a car belonging to someone I know as a favour and the sparkplugs were in so tight it took me over an hour to remove them -it was twitchy bottom time beleve me.
Thankfully they came out ok.

Crikey and there was me hoping that a glowplug changeover would be a straighforward job

Mike, when I did my Freda ones recently it took about 40 minutes to do from start to finish - I put some penetrating fluid on them for a few hours before undoing them.

Thanks KW - I'll remember to do that. Will WD40 do, or is there some magic brand I should buy (useful to have if so for whenever I have tight nuts
)

Luckly my plugs where not tight. When I replaced them I used a little bit of copper-ease on the threads, it's an anti-seize assembly compound, with extreme temperature tolerance. (-40 to +1150 degree C)

WD40 is a water dispersant. Yes in the majority of cases it will do the job but a better product to use is penetrating oil.

I used something called Freeway -Has yet to be beaten by a seized plug or nut - I use it all the time.

Thanks Steve L, It is the front one so I am trying the stud extractor first if that doesnt work will try the welding the nut at the local garage.will post the result tomorrow.
