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. 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.
