On a 265 cup, Is there a rubber washer or something on the gearbox oil drain plug that needs to be replaced if you take it out or can the original be re-used?
99% of the time it's a copper washer that is recommended to be replaced but can usually be reused fine
Cheers, don’t want to attempt it without knowing I shouldn’t come up against a problem caused by something as simple as a washer.
