Exhaust Emission Control System

Operation and required maintenance of the exhaust emission control devices used on this engine is covered in the INTRODUCTION - GASOLINE MODELS .

Induction System

The SFI provides the fuel/air mixture needed for combustion in the cylinders. The 6 solenoid-operated fuel injectors

1. are mounted between the fuel rail and the intake manifold.
2. meter fuel into the air intake stream in accordance with engine demand.
3. are positioned so that their tips direct fuel just ahead of the engine intake valves.

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.

Variable Camshaft Timing (VCT) System

The VCT system changes intake camshaft timing dependent on engine speed, load and oil temperature. Oil pressure advances and retards camshaft timing to improve low-speed and high-speed engine performance, engine idle quality and exhaust emissions.

PCV System

All engines are equipped with a closed-type PCV system recycling the crankcase vapors to the upper intake manifold.

Oil Pump

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

1. The oil pump is mounted on the front face of the cylinder block.
2. The inner rotor is piloted on the crankshaft post and is driven through flats on the crankshaft.
3. 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.
4. Oil pump displacement has been selected to provide adequate volume to make sure of correct oil pressure both at hot idle and maximum speed.
5. The relief valve calibration protects the system from excessive pressure during high-viscosity conditions.
6. The relief valve is designed to provide adequate connecting rod bearing lubrication under high-temperature and high-speed conditions.

Cooling System

The engine cooling system includes the following

1. Radiator
2. Timing chain driven coolant pump
3. Electric fan assembly(ies)
4. Degas bottle (aids in maintaining the correct volume of engine coolant)
5. Coolant thermostat
6. Coolant hoses

For basic engine mechanical concerns, refer to ENGINE SYSTEM - GENERAL INFORMATION . For driveability concerns, refer to the INTRODUCTION - GASOLINE MODELS .

1. Remove the valve covers. For additional information, refer to «VALVE COVER - LH»(ref-375983-S17384705352010103100000) and «VALVE COVER - RH»(ref-375983-S17064822752010103100000) .
2. Use a feeler gauge to measure the clearance of each valve and record its location. A midrange clearance is the most desirable: Intake: 0.15-0.25 mm (0.006-0.01 in) Exhaust: 0.360-0.460 mm (0.0142-0.0181 in)
3. If any of the valve clearances are out of specification, select new tappets using this formula: tappet thickness = measured clearance + the base tappet thickness - most desirable thickness. Select the tappets and mark the installation location.
4. If required, install the new selected valve tappets in the marked locations. For additional information, refer to «VALVE TAPPETS»(ref-375983-S36933607902010103100000) .

Note. During engine repair procedures, cleanliness is extremely important. Any foreign material, including any material created while cleaning gasket surfaces that enters the oil passages, coolant passages or the oil pan, may cause engine failure.

Note. Early build engines have 11 fastener valve covers, late build engines have 9 fastener valve covers. Do not attempt to install bolts in the 2 empty late build valve cover holes or damage to the valve cover will occur.

Note. Assembly of the engine requires various inspections/measurements of the engine components (engine block, crankshaft, connecting rods, pistons and piston rings). These inspections/measurements will aid in determining if the engine components will require replacement. For additional information, refer to ENGINE SYSTEM - GENERAL INFORMATION .

Note. On early build engines, the timing chain rides on the inner side of the RH timing chain guide. Late build engines are equipped with a different design RH timing chain guide that requires the timing chain to ride on the outer side of the RH timing chain guide. For service, all replacement RH timing chain guides will be the late build design.
