the cover to the body/housing.
CRANKCASE VENTILATION SYSTEM
Engine crankcase pressure and emissions are
vented into combustion chambers through the posi­
tive crankcase ventilation (PCV) system. The crank­
case ventilation system should have enough volume
to overcome crankcase pressure created by' piston
backwash. If a crankcase ventilation system-becomes
plugged, the crankcase pressure will increase and
force engine oil past the piston rings creating oil con­
sumption. Blockage of crankcase ventilation system
can occur at the vacuum source coupling, ventilation
