OIL FILTER CARTRIDGE
HOUSING

DESCRIPTION

The oil filter cartridge housing is attached to the
right side of the engine utilizing a seal between the
housing and engine block. The housing contains an
oil filter cartridge that cleans the engine oil coming
from the oil pump prior to it entering the main
engine oil gallery. The oil pressure switch is used to
provide the driver with engine oil pressure informa-
tion (Fig. 95).
Other components of the oil filter cartridge housing
(Fig. 95):
• By-Pass Valve: If the oil filter cartridge becomes
plugged, this valve opens allowing unfiltered oil to
enter the main engine oil gallery.
• Inlet Check Valve: This valve opens when engine
oil pressure pushes against it. After the engine is
shut off, the valve closes allowing oil to remain in the

oil filter cartridge housing.

• Drainback Valve: With the oil filter cartridge
installed, this valve is closed. As the oil filter cap and
oil filter cartridge are removed, the valve opens
allowing the reserve of oil in the cartridge housing to
drain back into the engine oil pan.
