Sectional view
The PCV valve is located on the upper side of the cylinder head cover.
The crankcase gases are sucked by the PCV valve into the intake manifold.
The PCV valve is opened by the vacuum in the intake manifold.
The amount of crankcase gases depends on the engine speed. The quantity sucked in is determined by the spring and the shape of the piston.
Deflection panel
Side view
The deflection plate is integrated into the cylinder head cover.
It prevents oil from being sucked in and burned in the combustion process.
The oil drops condense on the deflection plate and are then returned to the oil circuit.

PCV oil separator with integral PCV valve
The crankcase gases are freed of oil in the valve cover and in the PCV oil separator in order to prevent the oil from being sucked in and burned.
The PCV valve is located in the PCV oil separator.
The crankcase gases are sucked by the PCV valve into the intake manifold.
The PCV valve is opened by the vacuum in the intake manifold.
The amount of crankcase gases depends on the engine speed.
