Oil seal leak?

[treppid]

Hi guys.
Just finished first ever complete strip and rebuild of F2 engine. Started up ok . BUT, loads of smoke from right exhaust and oil spray, oil level in crankcase falling. Suspect clutch side crank oil seal is the problem? I was careful on the rebuild, new seals etc but looking at my Haynes again I think it says the small half moon, half washer thing should go in the groove on TOP of the end bearing so it sits in the UPPER crankcase half, I think I fitted it in the LOWER crankcase half? Can anyone point me in the right direction, can I get the upper crankcase off over the pistons, I really don't want to have to take them off the rods Any help much appreciated. Cheers...

I can't see that being the problem here. On the 4LO the half rings are fitted into the lower case, can't see as it makes any differance.
I think the problem may be the seal between the cases if its that bad...

Thanks mate, oh well I'll have to see if anything obvious turns up when I strip it....
Cheers....

Pistons have to come off to get the top case clear.
Also the half moons all fit into the lower case.
