CLEANING
CLEANING CYLINDER HEAD COVER
Using a suitable solvent, Clean and dry gasket mating surfaces on cylinderhead and rocker housing. Wipe gasket
dry and inspect for re-use.
INSPECTION - CYLINDER HEAD COVER
The cylinder head cover gasket and rocker housing gasket, are reusable.However, should cracks, nicks, or
tears be present in the rubber/silicone construction, the defective components should be replaced. Also replace gas-
ket if it is no longer flexible. Inspect cylinder head cover rubber isolated capscrews for cracks, nicks, or tears.Do not
reuse gasket if it has been removed from the groove in the rocker housing or cylinder head cover.
INSTALLATION
INSTALLATION - ROCKER HOUSING
1. Inspect rocker housing gasket for cuts, nicks, or tears. Replace if damagedorifgaskethascomeoutofgroove.
2. Inspect rocker housing gasket for proper installation in groove. Gasket bead must be centered in groove. A gas-
ket bead that is tilted to the side will cause an oil leak.

CAUTION: When installing rocker housing onto cylinder head, do not slide housing from side to side, The
gasket could fall out or be damaged.
3. Install the rocker housing. Carefully guide the rocker housing evenly down onto the cylinder head.
4. Install rocker housing bolts and tighten finger tight.
5. Torque bolts, working from center out, to 24 Nꞏm (18 ft. lbs.).
INSTALLATION - CYL HEAD COVER
NOTE: Gasket must be completely dry and free of oil before installation.
1. Position cylinder head cover (1) on top of cylinder head cover gasket (2).
2. Install bolts finger tight.

3. Starting with the center bolt, torque bolts (1) to 24
Nꞏm ( 18 ft. lbs. ).
4. Install breather tube (3) to cylinder head cover (2).
5. Install breather drain tube (4) to cylinder head
cover (2).
INSTALLATION - CYL HEAD COVER GASKET
1. Clean oil from cylinder head cover gasket
2. Inspect cylinder head cover gasket for cuts or damage. Replace if damaged.
3. Place cylinder head cover gasket on top of rocker housing (2).
4. Install injector solenoid nuts (1) at injectors. Torque to 1.25 Nꞏm ( 11 in. lbs. ).

5. Connect injector harness connectors (3) at cylinder head cover gasket.

VALVES & SEATS - INTAKE/EXHAUST
DESCRIPTION
The valves (1,2) are made of heat resistant steel, and
have chrome plated stems to prevent scuffing. The
intake and exhaust valves are both similar in head
diameter and overall length, but they have unique face
angles which makes them non-interchangeable. The
valves are distinguished by unique dimples on the
exhaust valve head (2).
The exhaust valve springs are made from high
strength, chrome silicon steel. The exhaust valve
springs are also exhaust brake compatible.
STANDARD PROCEDURE
STANDARD PROCEDURE - VALVES, GUIDES AND SPRINGS
REMOVAL
1. Remove cylinder head (Refer to 9 - ENGINE/CYL-
INDER HEAD - REMOVAL).
2. Support cylinder head on stands, or install head
bolts upside down (through combustion surface
side) to protect injector tips from damage from
work bench.
3. Install the valve spring compressor mounting base
(1) as shown.

4. Install the compressor top plate, washer, and nut.
Using a suitable wrench, tighten the nut (clockwise)
to compress the valve springs and remove the
locks.
5. Rotate the compressor nut counter-clockwise to
relieve tension on the springs. Remove the spring
compressor (1).
6. Remove the retainers (5), springs (4), valve seals
(3) (if necessary), and valves (2). Arrange or num-
ber all components so they can be installed in their
original locations.
7. Repeat the procedure on all cylinders to be
serviced.
CLEANING
Clean the valve stems with crocus cloth or a Scotch-Brite™ pad. Remove carbonwithasoftwirebrush.Clean
valves, springs, retainers, and valve retaining locks in a suitable solvent. Rinse in hot water and blow dry with com-
pressed air.

INSPECTION
Visually inspect the valves for abnormal wear on the
heads, stems, and tips. Replace any valve that is
worn out or bent.
Measure the valve stem diameter in three places as
shown.
