AN
CYLINDER HEAD COVER(S) (Continued)
Check the gasket for use in head cover installation.
If damaged, use a new gasket.
INSTALLATION
A cured gasket is part of the engine cylinder head
cover.
(1) Inspect the engine cylinder head cover for
cracks. Replace the cover, if cracked.
NOTE: The original dark grey gasket material
should NOT be removed. If sections of the gasket
material are missing or are compressed, replace the
engine cylinder head cover. However, sections with
minor damage such as small cracks, cuts or chips
may be repaired with a hand held applicator. The
new material must be smoothed over to maintain
gasket height. Allow the gasket material to cure
prior to engine cylinder head cover installation.
(2) If a replacement cover is installed, transfer the
CCV valve grommet the oil filler cap from the origi-
nal cover to the replacement cover.
(3) Install engine cylinder head cover. Tighten the
mounting bolts to 13 N·m (115 in. lbs.) torque.
(4) Connect the CCV hoses (Fig. 17).
(5) Connect negative cable to battery.
(6) Install the air inlet hose and resonator.

ROCKER ARMS

REMOVAL
(1) Remove the engine cylinder head cover (Refer
to 9 - ENGINE/CYLINDER
HEAD COVER(S) - REMOVAL).
(2) Check for rocker arm bridges which are caus-
ing misalignment of the rocker arm to valve tip area.
(3) Remove the capscrews at each bridge and pivot
assembly (Fig. 18). Alternately loosen the capscrews
one turn at a time to avoid damaging the bridges.
(4) Remove the bridges, pivots and corresponding
pairs of rocker arms (Fig. 18). Place them on a bench
in the same order as removed.
(5) Remove the push rods and place them on a
bench in the same order as removed.
(6) Clean all the components with cleaning sol-
vent.
(7) Use compressed air to blow out the oil passages
in the rocker arms and push rods.
CLEANING
Clean all the components with cleaning solvent.
Use compressed air to blow out the oil passages in
the rocker arms and push rods.

INSPECTION
Inspect the pivot surface area of each rocker arm.
Replace any that are scuffed, pitted, cracked or
excessively worn.
Inspect the valve stem tip contact surface of each
rocker arm and replace any rocker arm that is deeply
pitted.
Inspect each push rod end for excessive wear and
replace as required. If any push rod is excessively
worn because of lack of oil, replace it and inspect the
corresponding hydraulic tappet for excessive wear.
Inspect the push rods for straightness by rolling
them on a flat surface or by shining a light between
the push rod and the flat surface.
A wear pattern along the length of the push rod is
not normal. Inspect the engine cylinder head for
obstruction if this condition exists.
INSTALLATION
(1) Lubricate the ball ends of the push rods with
Mopar Engine Oil Supplement, or equivalent and
install push rods in their original locations. Ensure
that the bottom end of each push rod is centered in
the tappet plunger cap seat.
(2) Using Mopar
equivalent, lubricate the area of the rocker arm that
