I'm working my way through oil leaks on my Mk 2... The oil leak I'm looking at, at the moment is between the clutch and the primary chain case. I know there are some spun aluminium dishes, that can be riveted to the clutch chain wheel. At the moment, I don't want to invest the time in making and fitting these parts, so I have tried an alternative idea! Material is ultra high plastic. Hopefully, it's obvious from the photos, how the seal is made.
