POSITIVE CRANKCASE VENTILATION
DescriptionINFOID:0000000001161985
This system returns blow-by gas to the intake manifold.
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 inlet tubes 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 air inlet tubes under all condi-
tions.
Component InspectionINFOID:0000000001161986
1.CHECK PCV VALVE
With engine running at idle, remove PCV valve from rocker cover. 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 valve inlet.
Is the inspection result normal?
YES >> INSPECTION END
NO >> Replace PCV valve.

 Thickness of new valve lifter (B) can be identified by stamp
mark (A) on the reverse side (inside the cylinder).
 Stamp mark “300” indicates 3.00 mm (0.118 in) in thickness.
NOTE:
Available thickness of valve lifter: 26 sizes range 3.00 to 3.50 mm (0.1181 to 0.1378 in) in steps of 0.02
mm (0.0008 in) (when manufactured at factory). Refer to EM-123, "
Camshaft".
5. Install the selected valve lifter.
6. Install camshaft. Refer to EM-59, "
Exploded View".
7. Manually rotate crankshaft pulley a few rotations.
8. Make sure that valve clearances for cold engine are within specifications by referring to the specified val-
ues.
9. Install all removed parts in the reverse order of removal.
10. Warm up the engine, and check for unusual noise and vibration.

DRIVE BELT IDLER PULLEY
1. Insert the center shaft (1) into the slide groove of the spacer (2).
Fully screw in the adjusting bolt (3) in the belt loosening direc-
tion ( ).
 At that time, place the flange (a) of the adjusting bolt and the
seat (b) of the center shaft on the spacer.
2. Place each surface (c, d) of the spacer on the generator bracket.
Install the washer, idler pulley, and plate, and then temporarily
tighten the lock nut.
3. Installation is in the reverse order of removal.: 4.4 N·m (0.45 kg-m, 39 in-lb)
