2006 DODGE RAM SRT-10 engine

INSTALLATION
1. coat the valve stem with clean engine oil and insert
it into the cylinder head.
2. Install the valve stem seal. make sure the seal is
fully seated and that the garter spring at the top of
the seal is intact.
3. Install the spring and the spring retainer.
4. Using the valve spring compressor, compress the
spring and install the two valve spring retainer
halves.
5. Release the valve spring compressor and make
sure the two spring retainer halves and the spring
retainer are fully seated.
6. lubricate the camshaft journal with clean engine oil
then Position the camshaft (with the sprocket dowel
on the left camshaft at 11 o’clock and the right
camshaft at 12 o’clock), then position the camshaft
bearing caps.
7. Install the camshaft bearing cap retaining bolts.
Tighten the bolts 9-13 Nꞏm (100 in. lbs.) in 1/2 turn
increments in the sequence shown .
8. Position the hydraulic lash adjusters and rocker
arms (Refer to 9 - ENGINE/CYLINDER HEAD/
ROCKER ARM / ADJUSTER ASSY -
INSTALLATION).

ARM-VALVE ROCKER
DESCRIPTION
The rocker arms are steel stampings with an integral roller bearing. The rocker arms incorporate a 2.8 mm (0.11
inch) oil hole in the lash adjuster socket for roller and camshaft lubrication.
REMOVAL
NOTE: Disconnect the battery negative cable to
prevent accidental starter engagement.
1. Remove the cylinder head cover (Refer to 9 -
ENGINE/CYLINDER HEAD/CYLINDER HEAD
COVER(S) - REMOVAL).
2. For rocker arm removal on cylinder No. 4, Rotate
the crankshaft until cylinder No. 1 is at BDC intake
stroke.
3. For rocker arm removal on cylinder No. 1, Rotate
the crankshaft until cylinder No. 1 is at BDC com-
bustion stroke.
4. For rocker arm removal on cylinders No. 3 and No.
5, Rotate the crankshaft until cylinder No. 1 is at
TDC exhaust stroke.
5. For rocker arm removal on cylinders No. 2 and No.
6, Rotate the crankshaft until cylinder No. 1 is at
TDC ignition stroke.
6. Using special tool 8516 Rocker Arm Remover (2) ,
press downward on the valve spring, remove
rocker arm.
INSTALLATION
CAUTION: Make sure the rocker arms are installed
with the concave pocket over the lash adjusters.
Failure to do so may cause severe damage to the
rocker arms and/or lash adjusters.
NOTE: Coat the rocker arms with clean engine oil
prior to installation.
1. For rocker arm installation on cylinders No. 4,
Rotate the crankshaft until cylinder No. 1 is at BDC
intake stroke.
2. For rocker arm installation on cylinder No. 1,
Rotate the crankshaft until cylinder No. 1 is at BDC
combustion stroke.
3. For rocker arm installation on cylinders No. 3 and
No. 5, Rotate the crankshaft until cylinder No. 1 is
at TDC exhaust stroke.
4. For rocker arm installation on cylinders No. 2 and
No. 6, Rotate the crankshaft until cylinder No. 1 is
at TDC ignition stroke.
5. Using special tool 8516 (2) press downward on the
valve spring, install rocker arm.

6. Install the cylinder head cover (Refer to 9 - ENGINE/CYLINDER HEAD/CYLINDER HEAD COVER(S) - INSTAL-
LATION).

SPRINGS-VALVE
DESCRIPTION
The valve springs are made from high strength chrome silicon steel. The springs are NOT common for intake and
exhaust applications. The exhaust spring has an external damper. The valve spring seat is integral with the valve
stem seal, which is a positive type seal to control lubrication.
REMOVAL
1. Remove the cylinder head cover (Refer to 9 - ENGINE/CYLINDER HEAD/CYLINDER HEAD COVER(S) -

3. Remove the spark plug for the cylinder the valve spring and seal are to be removed from.
4. Apply shop air to the cylinder to hold the valves in place when the spring is removed.
NOTE: All six valve springs and seals are removed in the same manner; this procedure only covers one
valve seal and valve spring.
5. Using Special Tool 8387 Valve Spring Compressor, compress the valve spring.
NOTE: It may be necessary to tap the top of the valve spring to loosen the spring retainers locks enough to
be removed.
6. Remove the two spring retainer lock halves.
NOTE: the valve spring is under tension use care when releasing the valve spring compressor.
7. Remove the valve spring compressor.
NOTE: The valve springs are NOT common between intake and exhaust.

HEAD-CYLINDER-RIGHT
DIAGNOSIS AND TESTING - HYDRAULIC LASH ADJUSTER
A tappet-like noise may be produced from several items. Check the followingitems.
1. Engine oil level too high or too low. This may cause aerated oil to enter the adjusters and cause them to be
spongy.
2. Insufficient running time after rebuilding cylinder head. Low speed runningupto1hourmayberequired.
3. Turn engine off and let set for a few minutes before restarting. Repeat this several times after engine has
reached normal operating temperature.
4. Low oil pressure.
5. The oil restrictor in cylinder head gasket or the oil passage to the cylinder head is plugged with debris.
6. Airingestedintooilduetobrokenorcrackedoilpumppickup.
7. Worn valve guides.
8. Rocker arm ears contacting valve spring retainer.
9. Rocker arm loose, adjuster stuck or at maximum extension and still leaves lash in the system.
10. Oil leak or excessive cam bore wear in cylinder head.
11. Faulty lash adjuster.
a. Check lash adjusters for sponginess while installed in cylinder head and cam on camshaft at base circle.
Depress part of rocker arm over adjuster. Normal adjusters should feel firm when pressed quickly. When pressed
very slowly, lash adjusters should collapse.
b. Remove suspected lash adjusters, and replace.
c. Before installation, make sure adjusters are full of oil. This can be verified by little plunger travel when lash
adjuster is depressed quickly.

11. Rotate the crankshaft until the damper timing
mark is aligned with TDC indicator mark (2).

12. Verify the V6 mark on the camshaft sprocket is at the 12 o’clock position. Rotate the crankshaft one turn if
necessary.
13. Remove the crankshaft damper (Refer to 9 - ENGINE/ENGINE BLOCK/VIBRATION DAMPER - REMOVAL).
14. Remove the timing chain cover (Refer to 9 - ENGINE/VALVE TIMING/TIMINGBELT / CHAIN COVER(S) -
REMOVAL).
15. Lock the secondary timing chains to the idler
sprocket using Special Tool 8429 Timing Chain
Holding Fixture (1).
NOTE: Mark the secondary timing chain prior to
removal to aid in installation.
16. Mark the secondary timing chain, one link on
each side of the V6 mark on the camshaft drive
gear.
17. Remove the right side secondary chain tensioner
(Refer to 9 - ENGINE/VALVE TIMING/TIMING
BELT/CHAIN AND SPROCKETS - REMOVAL).

18. Remove the cylinder head access plug (1,2).
19. Remove the right side secondary chain guide
(Refer to 9 - ENGINE/VALVE TIMING/TIMING
BELT/CHAIN AND SPROCKETS - REMOVAL).
CAUTION: The nut on the right side camshaft
sprocket should not be removed for any reason,
as the sprocket and camshaft sensor target wheel
is serviced as an assembly. If the nut was
removed, torque nut to 5 Nꞏm (44 in. lbs.).
20. Remove the retaining bolt and the camshaft drive
gear.
CAUTION: Do not allow the engine to rotate.
severe damage to the valve train can occur.
CAUTION: Do not overlook the four smaller bolts at the front of the cylinderhead.Donotattempttoremove
the cylinder head without removing these four bolts.
CAUTION: Do not hold or pry on the camshaft target wheel for any reason. A damaged target wheel can
result in a vehicle no start condition.
NOTE: The cylinder head is attached to the cylin-
der block with twelve bolts.
21. Remove the cylinder head retaining bolts.
22. Remove the cylinder head and gasket. Discard
the gasket.
CAUTION: Do not lay the cylinder head on its gas-
ket sealing surface, do to the design of the cylin-
der head gasket any distortion to the cylinder
head sealing surface may prevent the gasket from
properly sealing resulting in leaks.
