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.
