Thanks Tim, although not back just yet, just rear based to the Airport (internet central) at Basra awaiting my flight home next weekend. Can't bloody wait!!! How is the engine rebuild going? Told you it was easy huh
Well, can't wait to get the Cerb out soon. I've also got to start planning a supercar 1 mile sprint day for sometime in summer, should be a hoot. Might also do Le Mans, although it will be a last minute thing. The Cerbergring thing looks awesome, shame the car will be in for its headlight conversion at the time!! 
Keep us posted, I may also start picking your brain soon about "doing a longbow" with our chassis. Whlst this is still current, I need another question answering....
Although it has been confirmed from 1 mechanic and 1 enthusiast, I would appreciate the PH massive on this.
Are you NOT supposed to use a brass sump washer on an alloy sump, which the Cerbera has?
Apparently because the brass bites into the alloy and makes it almost impossible to remove the sump plug. Where a nylon one does'nt, but does the same job.
Your thoughts...
Thanks

On closer inspection of my sump nut, the copper washer is compressed more on one side than the other.
And it WILL not come off. I have already split a socket piece trying to undo it. And I have done gazillions of oil changes over the years, but that has'nt happened before.
Taking the sump off looks like a bit of a bitch tbh. And all I wanted to do was make a 'between service' oil change.
Why does nothing ever go smoothly....

Sorry, I didn't realise you wanted to take the sump off with the engine still in the car - you can't do this as it mounts through the front cover. In order to get that off, you need the engine out! It sounds to me like someone has seriously overtorqued the sump nut, causing it to distort. I'd get a good quality hex socket (six sided, not a pointed one) and then use a flame to heat the sump bolt boss a bit, or maybe get the engine up to temp. Use an appropriate breaker bar if required to undo the bolt as slowly as possible. Even if it shears, drilling it out shouldn't be too difficult, possibly repair by helicoil? If the washer is more compressed on one side, it is possible some numpty has cross threaded it!!

Sounds suspeciously like someone's used air tools to tourque up the sump nut.
Follow Windsor's advice, but if you have to drill it in situ, it sounds stupid, but don't forget you have a full sump of oil behind it so it'll get a tad 'messy'!
Good luck
Tim
you can get some new jollop from loctite ( any industrial supplier should stock it) which is penetrating oil mixed with liquid nitrogen or something similar, basically it freezes the stuck fastener and the contraction allows the oil present in the jollop to get in and do its stuff.
Might be worth a go?
