Engine Identification
Always
refer to these labels when installation of new parts is necessary or
when checking engine calibrations. The engine parts often differ within a
CID family. Verification of the identification codes will make sure the
correct parts are obtained. These codes contain all the pertinent
information relating to the dates, optional equipment and revisions.

System Operation
Valve Train
The
valve train uses Direct Acting Mechanical Buckets (DAMB). The camshaft
lobes are positioned directly above mechanical buckets which are
positioned on top of the valves.
Twin Independent Variable Cam Timing (Ti-VCT) System
The
Twin Independent Variable Cam Timing (Ti-VCT) system allows variable
control of the valves that optimizes combustion at full load providing
improved power and low speed torque (broadening the torque curve) which
enables variable valve overlap which provides better fuel economy and
emissions and provides optimized cold start operation with improved
exhaust emissions.
PCV System
All
engines are equipped with a closed-type Positive Crankcase Ventilation
(PCV) system recycling the crankcase vapors to the intake manifold.
Lubrication System
The
engine lubrication system is of the force-feed type in which oil is
supplied under full pressure to the crankshaft, connecting rod bearings,
timing chain tensioners, camshaft bearing caps and VCT
solenoids. The flow of oil to the valve tappets and valve train is
controlled by a restricting orifice located in the cylinder head gasket.
The
lubrication system is designed to provide optimum oil flow to critical
components of the engine through its entire operating range.
The heart of the system is a positive displacement internal gear oil pump.
Generically, this design is known as a gerotor pump, which operates as follows:
-
The oil pump is chain driven off of the crankshaft. The oil pump is chain driven off of the crankshaft.
-
System pressure is limited by an integral,
internally-vented relief valve which directs the bypassed oil back to
the inlet side of the oil pump. System pressure is limited by an
integral, internally-vented relief valve which directs the bypassed oil
back to the inlet side of the oil pump.
-
Oil pump displacement has been selected to provide
adequate volume to make sure of correct oil pressure both at hot idle
and maximum speed. Oil pump displacement has been selected to provide
adequate volume to make sure of correct oil pressure both at hot idle
and maximum speed.
-
The relief valve calibration protects the system
from excessive pressure during high-viscosity conditions. The relief
valve calibration protects the system from excessive pressure during
high-viscosity conditions.

The relief valve is designed to provide adequate
connecting rod bearing lubrication under high temperature and high-speed
conditions. The relief valve is designed to provide adequate connecting
