Got the car back the other day and all seems OK, seems a bit more 'notchy' between some gear changes but when it starts clunking I'll start to worry but the down side of it now is that its got to back in for more work, seems they've managed to cock something up when re-assembling the unit and every morning when its cranked over theres one hell of a whine coming from the alternator (sounds that area) so whether its the bearings or belt to tight god knows.
Thought I'd give you all an update.
