POSITIVECRANKCASE VENTILATION
Description
This system returnsblow-by gastothe intake
manifold collector.
The positive crankcase ventilation (PCV)valveis
provided toconduct crankcase blow-bygastothe
intake manifold.
During partialthrottle operation ofthe engine, the
intake manifold suckstheblow-by gasthrough
the
pev
valve.
Normally, thecapacity ofthe valve issufficient to
handle anyblow-by andasmall amount ofventi-
lating air.
The ventilating airisthen drawn fromtheairduct into
thecrankcase. Inthis process theairpasses
through thehose connecting airinlet tubes to
rocker cover.
Under full-throttle condition,themanifold vacuum
is insufficient todraw theblow-by flowthrough
the valve. Theflow goes through thehose con-
nection inthe reverse direction.
On vehicles withanexcessively highblow-by, the
valve doesnotmeet therequirement. Thisis
because someofthe flow willgothrough the
hose connection tothe intake manifold collector
under allconditions.

PCV (Positive Crankcase Ventilation)
With engine running atidle, remove PCVvalve fromrocker
cover. Aproperly workingvalvemakes ahissing noiseasair
passes through it.Astrong vacuum shouldbefelt immediately
when afinger isplaced overthevalve inlet.

1. Check hosesandhose connections forleaks.
2. Disconnect allhoses andclean withcompressed air.Ifany
