I've got a slight oil leak from my R1 5PW engine, seems to be coming from the clutch rod where it passes through the clutch cover. Obvious answer...the oil seal has gone, however I have now changed it for new ones twice and it is still leaking. There doesn't seem to be any damage to the rod itself or the port in the clutch cover so I'm a bit stumped. The only thing is there is a fair bit of play in it (not side to side but in and out) which I'm not sure is normal or not?

Anyone else encountered this issue?
