Typical Cosworth, the damn diff has been leaking and made a right mess under the car I've got the diff out and I've managed to trace the leak back to where its coming from. It is coming from the centre of the part that attaches to the Prop (pic below). The oil is coming out of the centre part of this, is there a seal in this that I can replace and how do I get at it. Also the centre part turns which I am assuming it is meant to do!!!!



The diff is off a 2wd Saph Cossie, does any one know how much oil should be put? Idon't know if this will make a difference but its got Quaife LSD fitted.
