Sapporo L4-2555cc 2.6L (1982)
Positive Crankcase Ventilation: Testing and Inspection
Positive Crankcase Ventilation (PCV) System. 1982-86 2600cc engine & 1982-86 2000cc engine
Description
This system incorporates a PCV valve which is located at the rocker arm cover. With this system, fresh air is routed from the air cleaner to the
front of the valve cover and into the crankcase where the fresh air is mixed with the blow-by gasses. The mixture of fresh air and blow-by gasses
then passes through the PCV valve and is drawn through a hose to the intake manifold and to the combustion chamber. Under high speed or during
acceleration conditions, the blow-by gasses are drawn through the PCV valve to the intake manifold and through the breather to the air cleaner and
routed into the combustion chamber.
System Testing
1. Check if hoses or PCV valve is clogged.
2. Check air flow through hoses as shown.
