If there is oil in the header tank...oil cooler...relatively cheap to fix (garage should charge £300 or so or do it yourself) so for a facelift an absolute bargain at £225 if the car hasnt been driven while over heating and damaged other stuff...
That said, if its taxed and MOT'd then even if you have to change the engine it would still be cheap 
Cant see you needing it but I have a decent 2.5 engine from a manual car if it comes to it 
Hi first of all thanks for the quick response !.
I am a time served mechanic for ford so hopefully it is just the oil cooler. has thier been any problems with headgaskets on these ?.
i had a 2.0ltr old shape one which had done 213000 miles and was still going strong but mot was due and to much work for it to pass.
i may take that engine off you if worse comes to worse, pm me a price for it.
Thanks Ian.
