Separator

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.
