ok just as an update on this issue .

the problem was indeed gear oil getting on to the clutch plate caused by a badly fitted slave cylinder , they basically took no care when fitting this and damaged the oil seal within the slave cylinder .

this was a big name garage known across the uk , one which i will never use again nor will my friends and family , I wont name the garage as i dont want to get done for slander ,all i will say is it was not a ford garage !

in a nutshell they knew they cocked up but didnt want to admit it , so it was a bit of a stand off situation , where they had my car all in bits and i needed my car back on the road , so we eventually meet in the middle , a very much cowboy outfit if ever i see one .
hope this helps someone in the future
