1994 Volvo 850
Crankcase ventilation
The engine is provided with positive crankcase ventilation which prevents crankcase gases from being
released into the atmosphere. Instead, the crankcase gases are admitted to the intake manifold and
cylinders.
PCV system
The orifice nipple in the intake manifold and the filter at the end of the PCV hose in the air cleaner
should be inspected every 60,000 miles (96,000 km). Check/replace rubber hoses at the same time.
