Yes definitely the drain plug, when I removed it I did not notice the annealed copper washer, I'll add one and reassemble, thanks.No other suggestions apart from checking the copper washer.
Are you sure it's from the drain plug and not the fork assembly screw?

Hi all,'81 bike would have a Marzocchi fork. These have an o-ring to seal the drain plug...

?Hi all,
Can anyone who has replaced these O rings confirm the size? Guessing it’s OD-42mm CS-2.5mm
Is there a marzo/bmw part number ?
Also, same for the 2 little o rings under the damper adjust on the right fork leg?
Would similar sized viton seals do? Probably cheaper and available!
Cheers,
Stuart
