Ive a 48 ES2. It's always wet dumped but recently it's getting worse and has begun leaking from the crank oil seal quite badly as the sump fills. As I turn the crank by hand I can hear air coming from the seal. Should the seal be oil tight under these circumstances or should I consider replacing the seal? I've been informed that it would involve splitting the engine to replace the seal. I need to check the breather at the top of the crank. This requires removing the chaincase and drive gear. Unfortunately I am unable to lock the engine sufficiently to remove the nut. Any suggestions? I'm learning as I go.
