The first separation will happen when blow-
by gas passes through baffle plates in
cylinder head cover. Then oil and gas will
be separated due to cyclone effect after
entering the oil separator inlet port.
Separated oil returns to oil pan via oil drain
port and the gas will be burnt again after
entering the combustion chamber through
air duct hose via PCV valve that
opens/closes due to pressure differences
between the intake side and crankcase.
