z
are connected in series with the fuel pressure sensor.
z supply fuel from the fuel tank with a fuel pump mounted in the fuel tank.
A constant fuel pressure drop is maintained across the fuel injectors by the fuel pressure sensor. The
fuel pressure sensor:
zis positioned upstream from the fuel injectors on the fuel injection supply manifold.
Valve Train
The valve train operates as follows:
zball- tip hydraulic lash adjusters provide automatic lash adjustment.
z roller followers ride on the camshaft lobes, transferring the up-and- down motion of the
camshafts to the valves in the cylinder heads.
Positive Crankcase Ventilation System
All engines are equipped with a closed- type positive crankcase ventilation system recycling the
crankcase vapors to the upper intake manifold.
Lubrication System
The engine lubrication system operates as follows:
zoil is drawn into the oil pump through the oil pump screen cover and tube in the sump of the oil
pan.
z oil is pumped through the oil bypass filter on the left front side of the cylinder block.
z oil enters the main oil gallery where it is distributed to the crankshaft main journals and to both
cylinder heads.
z From the main journals, the oil is routed through cross- drilled passages in the crankshaft to
lubricate the connecting rod bearings. Controlled leakage through the crankshaft main bearings
and connecting rod bearings is slung radially outward to cool and lubricate the cylinder walls as
well as the entire connecting rod, piston and piston rings assembly.
z The left cylinder head is fed from a drilling into the supply passage feeding the main gallery at
the front of the cylinder block. The right cylinder head is fed from a drilling into the rear of the
main gallery. Main gallery pressure is reduced as it enters the cylinder head galleries through
fixed serviceable orifices located at the upper part of the feed passages. It is this reduced
pressure in the cylinder head galleries which feeds the camshaft journals, the hydraulic lash
adjusters and the primary and secondary timing chain tensioners.
z The camshaft lobe and roller followers are lubricated by splash created through valve train
operation.
Oil Pump
The lubrication system of the 4.6L (4V) engine 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 using top seal rotors. Generically this design is known as a gerotor
pump, which operates as follows.
zThe oil pump is mounted on the front face of the cylinder block.
z The inner rotor is piloted on the crankshaft post and is driven through flats on the crankshaft. Klj . 2 ba

NOTE:
Before assembling the cylinder block, all sealing surfaces must be free from chips, dirt, paint
and foreign material. Also, make sure the coolant and oil passages are clear.
5. Install the upper main bearings into the cylinder block and the lower main bearing into the crankshaft main bearing caps. Lubricate the main bearings with clean engine oil.
6. Install the crankshaft into the cylinder block.
7. CAUTION: Make sure the coated side of the thrust washer with the 5- mm wide oil
grooves faces the crankshaft thrust surface.
Push the crankshaft rearward and install the crankshaft thrust washer at the back of the No. 5
main boss. Klj . 4 ba

z
prevents hydrocarbon emissions from reaching the atmosphere.
z stores fuel vapors in the evaporative emission (EVAP) canister that are generated during
vehicle operation or hot soak, or vehicle refueling, until they can be consumed by the engine.
z routes the stored fuel vapors to the engine during engine operation.
z is controlled by the powertrain control module (PCM) which uses various sensor inputs to
calculate the desired amount of purge flow. The PCM regulates the purge flow, induced by the
application of intake manifold vacuum, by varying the duty cycle applied to the EVAP canister
purge valve.
z has an evaporative emission test port for test purposes.
The fuel vapors are routed:
zfrom the fuel tank through the fuel vapor control valve and fuel vapor vent valve.
z to the EVAP canister through a vapor line.
z to the engine when the EVAP canister purge valve is opened by the PCM.
The fuel tank pressure (FTP) sensor:
zmonitors the pressure levels in the fuel tank.
z communicates the pressure reading to the PCM during the OBDII leak test.
z is located in- line above the fuel tank and is serviced as part of the fuel vapor control valve tube
assembly.
The evaporative emission canister:
zis located in the left rear quarter panel.
z contains activated carbon.
z stores fuel vapor.
The fuel tank filler cap:
zrelieves system pressure above 14 kPa (56.21 inches H
2 O).
z relieves system vacuum below 3.8 kPa (15.26 inches H
2 O).
The canister vent solenoid: zis normally open.
z seals the EVAP system for the inspection and maintenance (I/M 240) test and OBDII leak and
pressure tests.
z is mounted to the evaporative emission canister.
z is repaired as a separate item.
The evaporative emission (EVAP) canister purge valve:
zis normally closed.
z regulates purging of the EVAP canister.
z is controlled by the PCM. Klj . 2 ba

DISASSEMBLY AND ASSEMBLY OF SUBASSEMBLIES
Torque Converter Turbine to Pump Stator Interference
Check
1. NOTE: Front pump support may remain in front pump support and gear during this test.
Position the torque converter with the pump drive up.
2. Install the front pump support to engage the mating splines of the front pump support shaft on the torque converter.
3. Install the forward clutch cylinder and shaft, engaging the splines with the rear clutch hub.
4. Check for stator to turbine interference. 1. Hold the front pump support stationary.
2. Attempt to rotate the forward clutch cylinder and shaft.
„The turbine and torque converter clutch assemblies should rotate in both
directions, not exceeding maximum torque of 9.5 Nm (7 lb- ft), without any signs of
metallic interference or scraping noise.
5. If interference exists, the stator front thrust washer may be worn, allowing the stator to hit the turbine. In such cases, a new or remanufactured torque converter must be installed.
zThe converter crankshaft pilot should be checked for nicks or damaged surfaces that
could cause interference when installing the torque converter into the crankshaft. Check
the converter front impeller hub for nicks or sharp edges that would damage the pump
seal.
