When you remove the flywheen check to see exactly where the oil is coming from. If it is coming from the seal you should see oil on the back surface of the flywheel stretching out to the outer edge. The inner o-ring will allow oil to enter through the center where the friction disc is. After reading your post and the fact that you have changed the seal more than once with the same problem, I am thinking you might have a leaking oil passage plug.
