The rubber packing is fitted in to maintain the
cylinder head cover 0.5 mm (0.02 in.) or so off the
cylinder head. This arrangement helps reduce noise
coming from the cylinder head.
(1) Cylinder Head Cover
Closed breather system has been adopted to
prevent the release of blow-by gas into the atmosphere.
After its oil content is filtered by oil shield (4), the
blow-by gas is fed back to the intake manifold through
breather valve (3) to be used for re-combustion.
