DIAGNOSIS AND TESTING - CYLINDER COMPRESSION PRESSURE
The results of a cylinder compressionpressure test can be utilized to diagnose several engine malfunctions.
Ensurethebatteryiscompletelychargedandtheenginestartermotorisingood operating condition. Otherwise the
indicated compression pressures may not be valid for diagnosis purposes.
1. Clean the spark plug recesses with compressed air.
2. Remove the spark plugs.
3. Disable the fuel system (Refer to 14 - FUEL SYSTEM/FUEL DELIVERY - DESCRIPTION).
4. Remove the ASD relay (Refer to 8 - ELECTRICAL/IGNITION CONTROL/AUTO SHUTDOWNRELAY-
REMOVAL).
5. Insert a compression pressure gauge and rotate the engine with the engine starter motor for three revolutions.
6. Record the compression pressure on the 3rd revolution. Continue the test for the remaining cylinders.
7. (Refer to 9 - ENGINE - SPECIFICATIONS) for the correct engine compression pressures.
DIAGNOSIS AND TESTING - CYLINDERCOMBUSTION PRESSURE LEAKAGE
The combustion pressure leakage test provides an accurate means for determining engine condition.
Combustion pressure leakage testing will detect:
Exhaust and intake valve leaks (improper seating).
Leaks between adjacent cylinders or into water jacket.
Any causes for combustion/compression pressure loss.
1. Check the coolant level and fill as required. DO NOT install the radiatorcap.
2. Start and operate the engine until it attains normal operating temperature, then turn the engine OFF.
3. Remove the spark plugs.
4. Remove the oil filler cap.
5. Remove the air cleaner hose.
6. Calibrate the tester according to the manufacturer’s instructions. The shop air source for testing should maintain
483 kPa (70 psi) minimum, 1,379 kPa (200 psi) maximum and 552 kPa (80 psi) recommended.
7. Perform the test procedures on each cylinder according to the tester manufacturer’s instructions. Set piston of
cylinder to be tested at TDC compression,While testing, listen for pressurized air escaping through the throttle
body, tailpipe and oil filler cap opening. Check for bubbles in the radiator coolant.
All gauge pressure indications should be equal, with no more than 25% leakage.
FOR EXAMPLE:At 552 kPa (80 psi) input pressure, a minimum of 414 kPa (60 psi) should be maintained in the
cylinder.

2. Position the new cylinder head gasket on the locat-
ing dowels.
CAUTION: When installing cylinder head, use care
not damage the tensioner arm or the guide arm.
3. Position the cylinder head onto the cylinder block.
Make sure the cylinder head seats fully over the
locating dowels.
NOTE: The four smaller cylinder head mounting
bolts require sealant to be added to them before
installing. Failure to do so may cause leaks.
4. Lubricate the cylinder head bolt threads with clean
engine oil and install the eight M11 bolts.
5. Coat the four M8 cylinder head bolts withMopar
Lock and Seal Adhesivethen install the bolts.
NOTE: The cylinder head bolts are tightened using
an angle torque procedure, however, the bolts are
not a torque-to-yield design.
6. Tighten the bolts in sequence using the following steps and torque values:
Step 1: Tighten bolts 1-8, 27 Nꞏm (20 ft. lbs.).
Step 2: Verify that bolts 1-8, all reached 27 Nꞏm (20 ft. lbs.), by repeatingstep 1 without loosening the bolts.
Tightenbolts9thru12to14Nꞏm(10ft.lbs.).
Step 3: Tighten bolts 1-8, 90 degrees.
Step 4: Tighten bolts 1-8, 90 degrees, again. Tighten bolts 9-12, 26 Nꞏm (19ft. lbs.)
7. Position the secondary chain onto the camshaft drive gear, making sure one marked chain link is on either side
of the V6 mark on the gear then using Special Tool 8428 Camshaft Wrench, position the gear onto the camshaft.
CAUTION: Remove excess oil from camshaft sprocket retaining bolt before reinstalling bolt. Failure to do so
may cause over-torqueing of bolt resulting in bolt failure.
8. Install the camshaft drive gear retaining bolt.
9. Install the left side secondary chain guide (Refer to 9 - ENGINE/VALVE TIMING/TIMING BELT/CHAIN AND
SPROCKETS - INSTALLATION).
10. Install the cylinder head access plug.
11. Re-set and install the left side secondary chain tensioner (Refer to 9 -ENGINE/VALVE TIMING/TIMING BELT/
CHAIN AND SPROCKETS - INSTALLATION).
12. Remove Special Tool 8429.
13. Install the timing chain cover (Refer to 9 - ENGINE/VALVE TIMING/TIMING BELT / CHAIN COVER(S) -
INSTALLATION).
14. Install the crankshaft damper (Refer to 9 - ENGINE/ENGINE BLOCK/VIBRATION DAMPER - INSTALLATION).
Tighten damper bolt 175 Nꞏm (130 Ft. Lbs.).
15. Install the power steering pump.
16. Install the fan blade assembly and fan shroud (Refer to 7 - COOLING/ENGINE/RADIATOR FAN - INSTALLA-
TION).
17. Install the cylinder head cover (Refer to 9 - ENGINE/CYLINDER HEAD/CYLINDER HEAD COVER(S) - INSTAL-
LATION).
18. Install the master cylinder and booster assembly (Refer to 5 - BRAKES/HYDRAULIC/MECHANICAL/POWER
BRAKE BOOSTER - INSTALLATION).
19. Install the intake manifold (Refer to 9 - ENGINE/MANIFOLDS/INTAKE MANIFOLD - INSTALLATION).
20. Refill the cooling system (Refer to 7 - COOLING - STANDARD PROCEDURE).

VALVES & SEATS - INTAKE/EXHAUST
DESCRIPTION
The valves are made of heat resistant steel and have chrome plated stems to prevent scuffing. Each valve is actu-
ated by a roller rocker arm which pivots on a stationary lash adjuster. All valves use three bead lock keepers to
retain the springs and promote valve rotation.
STANDARD PROCEDURE - REFACING
NOTE: Valve seats that are worn or burned can be
reworked, provided that correct angle and seat
width are maintained. Otherwise the cylinder head
must be replaced.
NOTE: When refacing valves (4) and valve seats, it
is important that the correct size valve guide pilot
be used for reseating stones. A true and complete
surface must be obtained.
1. Using a suitable dial indicator measure the center
of the valve seat. Total run out must not exceed
0.051 mm (0.002 in).
2. Apply a small amount of Prussian blue to the valve
seat, insert the valve into the cylinder head, while
applying light pressure on the valve rotate the
valve. Remove the valve and examine the valve
face. If the blue is transferred below the top edge
of the valve face, lower the valve seat using a 15
degree stone. If the blue is transferred to the bot-
tom edge of the valve face, raise the valve seat
using a 65 degree stone.
3. When the seat is properly positioned the width of the intake seat must be 1.75 - 2.36 mm (0.0689 - 0.0928 in.)
and the exhaust seat must be 1.71 - 2.32 mm (0.0673 - 0.0911 in.).
4. Check the valve spring (6) installed height after refacing the valve andseat. The installed height for both intake
and exhaust valve springs must not exceed 40.74 mm (1.6039 in.).
5. The valve seat and valve face must maintain a face angle of 44.5 - 45 ° angle.

2. Position the new cylinder head gasket on the locat-
ing dowels.
CAUTION: When installing cylinder head, use care
not damage the tensioner arm or the guide arm.
3. Position the cylinder head onto the cylinder block.
Make sure the cylinder head seats fully over the
locating dowels.
NOTE: The four M8 cylinder head mounting bolts
(1) require sealant to be added to them before
installing. Failure to do so may cause leaks.
4. Lubricate the cylinder head bolt threads with clean
engine oil and install the eight M10 bolts.
5. Coat the four M8 cylinder head bolts withMopar
Lock and Seal Adhesivethen install the bolts.
NOTE: The cylinder head bolts are tightened using
an angle torque procedure, however, the bolts are
not a torque-to-yield design.
6. Tighten the bolts in sequence using the following steps and torque values:
Step 1: Tighten bolts 1-8, 27 Nꞏm (20 ft. lbs.).
Step 2: Verify that bolts 1-8, all reached 27 Nꞏm (20 ft. lbs.), by repeatingstep 1 without loosening the bolts.
Tightenbolts9thru12to14Nꞏm(10ft.lbs.).
Step 3: Tighten bolts 1-8, 90 °.
Step 4: Tighten bolts 1-8, 90 °, again. Tighten bolts 9-12, 26 Nꞏm (19 ft. lbs.)

INSTALLATION
1. Lubricate the crankshaft flange with engine oil.
2. Position the magnetic seal guide Special Tool
8349-2 onto the crankshaft rear face. Then position
the crankshaft rear oil seal (1) onto the guide (2).
3. Using Special Tools 8349 Crankshaft Rear Oil Seal
Installer (2) and C-4171 Driver Handle (3), with a
hammer, tap the seal (1) into place. Continue to
tap on the driver handle until the seal installer
seats against the cylinder block crankshaft bore.
4. Install the flexplate.
5. Install the transmission.
