Mercedes-Benz 603 Service Manual page 55

The blow-by gasses from the crankcase flow
through the oil separator (126) into the cylinder
head cover and a hose to the distribution pipe
(140) on the intake manifold depending on the
intake manifold vacuum.
These gasses are distributed uniformly to all
cylinders by the intake manifold and drawn into
the combustion chambers together with the
intake air.
The oil deposited in the oil separator runs back
to the cylinder head through the return pipe
(127).
