Arrrrgh! "Eezee-outs" are the devil's work!
Don't use them EVER. EVER.
We do a good trade in sparking out snapped eezeeouts that the misguided have "applied" in desperation. They only work safely if a bolt has been "wiped" off sideways i.e. truly sheared off or snapped in tension.
If a bolt/stud has been twisted off, that means that the force needed to wring it off was less than the force to release the threads. A EZ will not help in this case, as it applies a wedging action to gain purchase in the drilled hole, making things worse...
You have been warned. I hate to see folks suffer needlessly and that's coming from a precision engineer!
Jebiga - sounds like you need a helicoil/wire thread insert kit.

problem was that the aaz was rusted on that side bloody british salted roads 
so the mounting holes were corroded we re tapped them but that and a few bangs on the course must have pulled them out my sump seems to be resting on the sumpguard and making a bit of a racket never mind the vibrations, anyhow will have a good look tomorrow when I'm off work was thinking might be worthwhile putting a piece of rubber type strip between the sump and the guard to prevent this happening again and act as some type of support for the engine has this ever happened to anyone else? sorry for lack of punctuation but its 4.30am and have only managed about 16 hours sleep since sat
