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.
