CHECK ONE-WAY FUEL VALVE-II

1.

Make sure that fuel is drained from the tank.

2.

Remove fuel filler tube and hose.

3.

Check one-way fuel valve for operation as follows.
When a stick is inserted, the valve should open, when removing
stick it should close.
Do not drop any material into the tank.

POSITIVE CRANKCASE VENTILATION

POSITIVE CRANKCASE VENTILATION

PFP:11810

Description

UBS00DDU

This system returns blow-by gas to the intake collector.
The positive crankcase ventilation (PCV) valve is provided to conduct crankcase blow-by gas to the intake
manifold.
During partial throttle operation of the engine, the intake manifold sucks the blow-by gas through the PCV
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 air duct into the crankcase. In this process the air passes through the
hose connecting air inlet tubes to rocker cover.
Under full-throttle condition, the manifold vacuum is insufficient to draw the blow-by flow through the valve.
The flow goes through the hose connection in the reverse direction.
On vehicles with an excessively high blow-by, the valve does not meet the requirement. This is because some
of the flow will go through the hose connection to the intake collector under all conditions.

Inspection

UBS00DDV

PCV (POSITIVE CRANKCASE VENTILATION) VALVE

With engine running at idle, remove PCV valve from breather sepa-
rator. A properly working valve makes a hissing noise as air passes
through it. A strong vacuum should be felt immediately when a finger
is placed over the valve inlet.

VENTILATION HOSE

1.

Check hoses and hose connections for leaks.

Disconnect all hoses and clean with compressed air. If any hose
cannot be freed of obstructions, replace.
