CRANKCASE

EMISSION

SYSTEM

This

system
returns
blow

by

gas
to
both
the

intake

manifold
and
carburetor

air
cleaner
The
Posirive
Crankcase
Ventilation

PCV
valve
is

provided
to
conduct
crankcase
blow

by

gas
to
the
intake

manifold

Duirng
partial
throttle

operation
of

the

enigne

the
intake

manifold

sucks
the

blow

by
gas
through
the

valve

Normally
the

capacity
of
the

valve
is
sufficient
to

handle

any
blow

by
and

a
small

amount
of

ventilating
air

The

ventilating
air

is
then

drawn
from

the
clean
side
of

the
carburetor
air

cleaner

through
the

tube

connecting

carburetor
air

cleaner
to
rocker
cover

intu
the
crankcase

Under
full

throttle
condition
the
manifold
vacuum
is

insufficient
to
draw

the
blow

by
flow

through
the
valve

and
its
flow

goes

through
the
tube

connection
in
the

reverse
direction

In
cars
with
an

excessively
high
blow

by

some
of

the
flow

will
