engine crankcase ventilation system
During engine breather system maintenance remove valve cap
4 (Fig. 9.4), ventilation hoses and tubes, vacuum valve cap 3, the
valve membrane and spring and clean the removed parts. Clean
the holes of valve cap ventilation necks, holes 7 of separated oil
drain, sensing hole 8 in the vacuum valve case and venting holes
in the vacuum valve cap. The oil baffle 5 shall be flushed mounted
on the valve cap. Check the membrane for damage and breakage.
When re-assembling, ensure tightness of connections.
WARNING! DO NOT operate the Engine with a non pressure-
tight ventilation system and open oil socket. It may cause higher
oil consumption via crankcase blow-by gas evacuation and
environmental pollution. To prevent the ventilation system, tight
close the oil socket cap and set the oil level indicator to the fix.
