560 twin crank case breather

[SOHC]

I have been working on a mish mash of parts 1959-62, the bike gushed oil uncontrollably from everywhere, I have striped it down to repair other parts


I carn't see how the crankcase can breathe? the nut that holds the rotor on has a valve but the crank has no passage.

There is 4 holes in that cover on the end of the inlet cam but no timed breather inside, or fittings for hoses anywhere on the crankcases.


What years did the breathers change?

Sorted, it was in the end of the crank after all.
