Hello Ross,

The centre bearing has a seal either side. As this main bearing is fed lube from the g/box if these seals go g/box oil will start to get past the seal and you will have a very smokey exhaust :) . As your g/box oil was well down it sounds as if your engine is a typical example of this happening. To renew the centre seals you have to disassemble the crank, I'm sure that someone on your side of the pond will recommend a good crank rebuilder.

Cheers Geoff

Does it smoke from one, or both pipes? Bear in mind that if the silencers are full of oil they will smoke as this burns off.
