LUBRICATION
DIAGNOSIS AND TESTING
DIAGNOSIS AND TESTING - CHECKING ENGINE OIL PRESSURE
1. Remove oil pressure sending unit and install gauge assembly C-3292.
2. Run engine until thermostat opens.
3. Oil Pressure:
Curb Idle–25 kPa (4 psi) minimum
3000 rpm–170 - 758 kPa (25 - 110 psi)
4. If oil pressure is 0 at idle, shut off engine. Check for a clogged oil pick-up screen or a pressure relief valve stuck
open.
DIAGNOSIS AND TESTING - ENGINE OIL LEAK
Begin with a thorough visual inspection of the engine, particularly at thearea of the suspected leak. If an oil leak
source is not readily identifiable, thefollowingstepsshouldbefollowed:
1. Do not clean or degrease the engine at this time because some solvents maycause rubber to swell, temporarily
stopping the leak.
2. Add an oil soluble dye (use as recommended by manufacturer). Start the engine and let idle for approximately 15
minutes. Check the oil dipstick to make sure the dye is thoroughly mixed as indicated with a bright yellow color
under a black light.
3. Using a black light, inspect the entire engine for fluorescent dye, particularly at the suspected area of oil leak. If
the oil leak is found and identified, repair per service manual instructions.
4. If dye is not observed, drive the vehicle at various speeds for approximately 24 km (15 miles), and repeat inspec-
tion.If the oil leak source is not positively identified at this time, proceed with the air leak detection test
method.
Air Leak Detection Test Method
1. Remove the PCV valve from the IAFM. Cap or plug the PCV valve grommet.
2. Attach an air hose with pressure gauge and regulator to the dipstick tube.
CAUTION: Do not subject the engine assembly to more than 20.6 kPa (3 PSI) of test pressure.
3. Gradually apply air pressure from 1 psi to 2.5 psi maximum while applyingsoapy water at the suspected source.
Adjust the regulator to the suitable test pressure that provide the best bubbles which will pinpoint the leak
source. If the oil leak is detected and identified, repair per service manual procedures.
4. If the leakage occurs at the rear oil seal area, refer to the section, Inspection for Rear Seal Area Leak.
5. If no leaks are detected, turn off the air supply and remove the air hose and all plugs and caps. Install the PCV
valve.
6. Clean the oil off the suspect oil leak area using a suitable solvent. Drive the vehicle at various speeds approx-
imately 24 km (15 miles). Inspect the engine for signs of an oil leak by usinga black light.
INSPECTION FOR REAR SEAL AREA LEAKS
Since it is sometimes difficult to determine the source of an oil leak in therear seal area of the engine, a more
involved inspection is necessary. The following steps should be followedto help pinpoint the source of the leak.
If the leakage occurs at the crankshaft rear oil seal area:
1. Disconnect the battery.
2. Raise the vehicle.
3. Remove torque converter or clutch housing cover and inspect rear of block for evidence of oil. Use a black light
to check for the oil leak:
a. Circular spray pattern generally indicates seal leakage or crankshaftdamage.

OIL
STANDARD PROCEDURE - ENGINE OIL SERVICE
The engine oil level indicator is located at the left hand of the engine on the 5.7L engines.
CRANKCASE OIL LEVEL INSPECTION
CAUTION: Do not overfill crankcase with engine oil, pressure loss or oil foaming can result.
Inspect engine oil level approximately every 800 kilometers (500 miles).Unless the engine has exhibited loss of oil
pressure, run the engine for about ten minutes before checking oil level. Checking engine oil level on a cold engine
is not accurate.
To ensure proper lubrication of an engine, the engine oil must be maintained at an acceptable level. The acceptable
levels are indicated between the ADD and SAFE marks on the engine oil dipstick.
1. Position vehicle on level surface.
2. With engine OFF, allow approximately five minutes for oil to settle to bottom of crankcase, remove engine oil
dipstick.
3. Wipe dipstick clean.
4. Install dipstick and verify it is seated in the tube.
5. Remove dipstick, with handle held above the tip, take oil level reading.
6. Add oil only if level is below the ADD mark on dipstick.
ENGINE OIL CHANGE
Change engine oil at mileage and time intervals described in Maintenance Schedules (Refer to LUBRICATION &
MAINTENANCE/MAINTENANCESCHEDULES - DESCRIPTION).
Run engine until achieving normal operating temperature.
1. Position the vehicle on a level surface and turn engine off.
2. Hoist and support vehicle on safety stands.
3. Remove oil fill cap.
4. Place a suitable drain pan under crankcase drain.
5. Remove drain plug from crankcase and allow oil to drain into pan. Inspectdrain plug threads for stretching or
other damage. Replace drain plug if damaged.
6. Install drain plug in crankcase. Torque to 34 Nꞏm ( 25 ft. lbs.).
7. Lower vehicle and fill crankcase with specified type and amount of engine oil described in this section.
8. Install oil fill cap.
9. Start engine and inspect for leaks.
10. Stop engine and inspect oil level.
USED ENGINE OIL DISPOSAL
Care should be exercised when disposing used engine oil after it has been drained from a vehicle engine. Refer to
the WARNING at beginning of this section.

INSPECTION
CAUTION: Oil pump pressure relief valve and
spring should not be removed from the oil pump.
If these components are disassembled and or
removed from the pump the entire oil pump
assembly must be replaced.
1. Remove the pump cover.
2. Clean all parts thoroughly. Mating surface of the oil
pump housing should be smooth. If the pump cover
is scratched or grooved the oil pump assembly
should be replaced.
3. Slide outer rotor into the body of the oil pump.
Press the outer rotor to one side of the oil pump
body and measure clearance between the outer
rotor (2) and the body. If the measurement is
0.235mm (0.009 in.) or more the oil pump assem-
bly must be replaced.
4. Install the inner rotor in the into the oil pump body.
Measure the clearance between the inner (3) and
outer rotors (1). If the clearance between the rotors
is .150 mm (0.006 in.) or more the oil pump
assembly must be replaced.
5. Place a straight edge (1) across the body of the oil
pump (between the bolt holes), if a feeler gauge (2)
of .095 mm (0.0038 in.) or greater can be inserted
between the straightedge and the rotors, the pump
must be replaced.
6. Reinstall the pump cover. Torque fasteners to 15
Nꞏm (132 in. lbs.).
NOTE: The 5.7 Oil pump is released as an assem-
bly. There are no DaimlerChrysler part numbers for
Sub-Assembly components. In the event the oil
pump is not functioning or out of specification it
must be replaced as an assembly.

MANIFOLD - EXHAUST
DESCRIPTION
The exhaust manifolds are log style with a patented flow enhancing design to maximize performance. The exhaust
manifolds are made of high silicon molybdenum cast iron. A perforated coregraphite exhaust manifold gasket is
used to improve sealing to the cylinder head. The exhaust manifolds are covered by a three layer laminated heat
shield for thermal protection and noise reduction. The heat shields are fastened with a torque prevailing nut that is
backed off slightly to allow for the thermal expansion of the exhaust manifold.
OPERATION
The exhaust manifolds collect the engine exhaust exiting the combustion chambers, then channels the exhaust
gases to the exhaust pipes attached to the manifolds.
