What it was doing was popping the seal slightly on the tight half and dripping oil a fair bit over 100 miles. Slackened chain off, and it stopped the leak, no problems since.
Sprocket seal is a few quid, round circle thing with a bit of rubber on it. I bought one just in case, never used it.
It's a rarity it happens, but I have proof it does. The rubber if made to kink a little allows oil out as it unseats itself. Slack off, pops back in to correct position.

the thing people dont realize is how much a shaft will move under pressure,if the shaft did not bend it would break,but because the seal is near the bearing this movement is very small and in your case did not apear to do any long term harm,but normally this will shorten the bearing and seal life,( just seen the above post) if it was leaking from the outer edge of the seal then the bearing was moving in the case and that is very bad thing to happen and the amount of stress put on the cases would normally damage the cases,
