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(s)
4. Degas bottle (aids in maintaining the correct volume of engine coolant)
5. Coolant thermostat
6. Coolant hoses

Scheme 414

1. Remove the valve covers. For additional information, refer to «VALVE COVER - LH»(ref-355690-S04292587482010012800000) and «VALVE COVER - RH»(ref-355690-S35447308712010012800000) .
2. NOTE: Engine must be at room temperature before measuring. The valve clearance must be measured with the camshaft at base circle. The engine will have to be rotated with the crankshaft pulley bolt to bring each valve to base circle. 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. NOTE: The number on the valve tappet reflects the thickness of the valve tappet. For example, a tappet with the number 3.310 has the thickness of 3.31 mm (0.13 in). 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-355690-S11504327562010012800000) .

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. 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.

Note. For additional information, refer to the exploded view under the ASSEMBLY procedure .

1. NOTE: This procedure is for selecting bearings using a new crankshaft. Select the crankshaft main bearings for each crankshaft journal. Read the code on the crankshaft flange. Read the code on the cylinder block face. The first letter after the first asterisk makes up the code for main No. 1 and the next letter for main No. 2. The first letter after the second asterisk makes up the code for main No. 3 and the last letter for main No. 4.
2. Using the chart, choose a bearing for each main. Match the block and crankshaft code with its corresponding column or row, by reading across the "crankshaft" row and down the "block" column. If the block code is *BM*QS* and the crankshaft code is *OL*PO*, Main No. 1 should be built with grade 1 bearings, as determined by the intersection of the B block column and the O crankshaft row on the chart. Mains No. 2, No. 3 and No. 4 should all be grade 2.
3. NOTE: The rod cap installation must keep the same orientation as marked during disassembly or engine damage may occur. Using the original connecting rod cap bolts, install the connecting rod caps and bolts. Tighten the bolts in 3 stages. Stage 1: Tighten to 23 Nm (17 lb-ft). Stage 2: Tighten to 43 Nm (32 lb-ft). Stage 3: Tighten an additional 90 degrees.
4. Measure the connecting rod large end bore in 2 directions. Remove the bolts and the rod cap. Discard the connecting rod cap bolts.
5. Measure each of the crankshaft connecting rod bearing journal diameters in at least 2 directions.
6. Using the chart, select the correct connecting rod bearings for each crankshaft connecting rod journal.
7. NOTE: Before assembling the cylinder block, all sealing surfaces must be free of chips, dirt, paint and foreign material. Also, make sure the coolant and oil passages are clear. Lubricate the upper crankshaft main bearings with clean engine oil and install the 4 crankshaft main bearings in the cylinder block.
8. NOTE: Do not install the upper thrust bearings until the crankshaft is installed. NOTE: Lubricate the thrust surfaces of the crankshaft with clean engine oil. Install the crankshaft onto the upper main bearings.
9. NOTE: Make sure the side of the thrust washer, with the wide oil grooves, faces the crankshaft thrust surface. Push the crankshaft rearward and install the rear crankshaft upper thrust washer at the back of the No. 4 rear bulkhead.
10. NOTE: Make sure the side of the thrust washer, with the wide oil grooves, faces the crankshaft thrust surface. Push the crankshaft forward and install the front crankshaft upper thrust washer at the front of the No. 4 rear bulkhead.
11. Lubricate the crankshaft lower main bearings with clean engine oil and install them into the main bearing caps. Visually check seating and squareness of the bearings to make sure of proper seating in caps.
12. Position the No. 1, No. 2 and No. 3 main bearing caps on the cylinder block and, keeping the caps as square as possible, alternately draw the caps down evenly using the new bolts until the main bearing caps are seated.
