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.

Engine Code Information Label

The engine code information label, located on the front cover, contains the following:

Item Description
1 Engine part number
2 Bar code
3 Dearborn engine plant
4 Engine displacement
5 Bar code
6 Bar code
6 Running number
7 Engine build date (DDMMYY)
8 Plant shift line

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 rod bearing lubrication under high temperature and high-speed conditions.
