MANIFOLD-INTAKE
DIAGNOSIS AND TESTING
INTAKE MANIFOLD LEAKS
An intake manifold air leak is characterized by lower than normal manifoldvacuum, rough idle, or engine misfire.
WARNING: USE EXTREME CAUTION WHEN THE ENGINE IS OPERATING. DO NOT STAND IN ADIRECT LINE
WITH THE FAN. DO NOT PUT YOUR HANDS NEAR THE PULLEYS, BELT OR THE FAN. DO NOT WEAR
LOOSE CLOTHING.
1. Start the engine.
2. Spray a small stream of water (Spray Bottle) at the suspected leak area.
3. If engine RPM’S change, the area of the suspected leak has been found.
4. Repair as required.
REMOVAL
NOTE: Care must be taken to protect the intake
manifold powder coating from scrapes and abra-
sions.
1. Perform the fuel system pressure release proce-
dure,before attempting any repairs.(Refer to 14
- FUEL SYSTEM/FUEL DELIVERY - STANDARD
PROCEDURE - FUEL SYSTEM PRESSURE
RELEASE PROCEDURE).
2. Disconnect negative battery cable.
3. Disconnect throttle body air inlet duct, IAT sensor,
CCV hose and remove air cleaner cover (Refer to
9 - ENGINE/AIR INTAKE SYSTEM - REMOVAL).
4. Disconnect throttle cable (2) from throttle cam.
Remove throttle cable from bracket and set aside.
5. Disconnect speed control cable from throttle cam
and set aside.
Page 2058 of 5267
6. Disconnect brake booster vacuum hose from the
intake manifold and set aside.
WARNING: WRAP A SHOP TOWEL AROUND FUEL
LINE TO CATCH ANY GASOLINE SPILLAGE.
7. Disconnect fuel line quick connect fitting from fuel
rail (Refer to 14 - FUEL SYSTEM/FUEL DELIV-
ERY/QUICK CONNECT FITTING - STANDARD
PROCEDURE).
8. Disconnect the following electrical connectors:
Left cylinder head fuel injectors
MAP sensor
Engine Coolant Temperature (ECT) Sensor
Idle Speed Control Sensor (ISC)
Throttle Position Sensor (TPS) (1)
Right cylinder head fuel injectors
9. Carefully separate the fuel injector harness push
pins from the intake manifold.
Page 2062 of 5267
10. Reconnect the following electrical connectors:
Left cylinder head fuel injectors
Engine Coolant Temperature (ECT) Sensor
MAP sensor
Idle Speed Control
Throttle Position Sensor
Right cylinder head fuel injectors
11. Install air cleaner cover assembly, connect throttle
body air inlet hose, CCV hose and connect the
Intake Air Temperature Sensor (Refer to 9 -
ENGINE/AIR INTAKE SYSTEM - INSTALLATION).
12. Connect negative battery cable.
13. With the Scan Tool, use the ASD Fuel System
Test to pressurize fuel system to check for leaks.
CAUTION: When using the ASD Fuel System Test,
the Auto Shutdown (ASD) relay will remain ener-
gized for 7 minutes or until the ignition switch is
turned to the OFF position, or Stop All Test is selected.

5. Inspect the push rods. Replace worn or bent push
rods as necessary.
6. Install push rods. Install rocker arms and pedestal
assemblies into their original positions. Ensure
push rods are seated properly under each rocker
arm.Tightenrockerarmboltsto35Nꞏm(26ft.
lbs.).
7. Install exhaust manifold(s) and gasket(s) (Refer to
9 - ENGINE/MANIFOLDS/EXHAUST MANIFOLD -
INSTALLATION).
8. Install exhaust manifold heat shields.
9. Install cylinder head covers (Refer to 9 - ENGINE/
CYLINDER HEAD/CYLINDER HEAD COVER(S) -
INSTALLATION).
10. Position and install the oil level indicator tube.
Tighten fastener to 11 Nꞏm (95 in. lbs.).
11. Connect CCV hoses to cylinder head covers.
12. Install the spark plug wires and plug wire retain-
ers.
13. Install intake manifold (Refer to 9 - ENGINE/MAN-
IFOLDS/INTAKE MANIFOLD - INSTALLATION).
14. Raise and support the vehicle.
15. Connect the exhaust systemto the exhaust manifolds.
16. Drain the engine oil (Refer to 9 - ENGINE/LUBRICATION/OIL - STANDARD PROCEDURE).
17. Lower the vehicle.
18. Fill engine oil to the proper level (Refer to LUBRICATION & MAINTENANCE/FLUID TYPES - DESCRIPTION),
(Refer to LUBRICATION & MAINTENANCE/FLUID TYPES - SPECIFICATIONS).
19. Fill the cooling system (Refer to 7 - COOLING/ENGINE - STANDARD PROCEDURE - FILLING COOLING
SYSTEM).
20. Connect negative battery cable.
21. Install the air cleaner cover, throttle inlet duct and connect the IAT sensor and CCV hose.
22. Start engine and inspect for leaks.

may occur. Use only a plastic scraper and Mopar
Brake Parts Cleaner or the equivalent.
1. Be sure mating surfaces of chain case cover and
cylinder block are clean and free from burrs.
Crankshaft oil seal must be removed to insure cor-
rect oil pump engagement.

3. Position the oil pump inner rotor mating flats in the
same position as the crankshaft drive flats.
4. Install the timing chain cover onto crankshaft.
Ensure the oil pump is engaged on the crankshaft
correctly or severe damage may result (Refer to 9 -
ENGINE/LUBRICATION/OIL PUMP -
INSTALLATION).
