The bubbling paint all over the alternator casing is the giveaway that it's leaking dude. Are u finding that the Oberon means that the clutch 'drags' or is it okay?
To be honest i've only been round the block on it, it did seem from memory to not be altogether smooth. I'll pay more attention to it on the next ride. Keep checking the garage floor and no wet patch so it's definitely cured, and the slave was the culprit.
