OILING SYSTEM
COMPONENTS
Rear Oil Manifold (3.3 L models)
The rear oil manifold receives oil from the primary
manifold and distributes it to the cylinder sleeves.
Rear Oil Pump (3.4 L models)
The oil injection pump is an electric (12 V) actua-
tor style pump. It d raws oil from a fit ting at the oil
injection pump and supplies pressurized oil to the
cylinder sleeve s. The EMM su pplies 12 V and
controls activation of the pump
Electrical Circuit (12 V)
The rear oil pump is powered by the 12 V electri-
cal circuit. The EMM controls pu mp operation by
rapidly connecting and disconnecting the pump’ s
internal coil to ground.
The EMM monitors the o il injection pump electr i-
cal circuit. If the circuit is open, the EMM:
LOW OIL Warning
A sen ding unit in the oil t ank p ick-up assembly
monitors the oil level in the oil tank.
If the oil level falls below one-quarter capacity, the
EMM signals:
An optional oil tank sending unit kit is available to
display actual oil level through an I-Command net-
work.
NO OIL Warning
The EMM monitors th e electric al circuit of the oil
pressure sensor. If the sen sor or circuit fails, or if
there is a lack of oil pressure in the oil distribution
manifold, the EMM:
