i tried fitting my new flywheel and clutch to my 1.8t this weekend and was advised to replace the rear seal. i bought a new one from the main dealer along with a gasket. it comes as a complete housing. The new one is a slightly different design to the old one. first drive up the road and engine oil is pouring out the box.so everything back off-the oil seems to leak from the seal part in the middle which doesnt look like a tight enough fit to seal. also the gasket seems a bad fit against the rubber seal of the housing. i tried it without the gasket but it still leaked out. anyone have any ideas? thanks.
