of wood between the jack and the
front edge of the oil pan. Raise the
front of the engine about 2 inches to
allow clearance for removal of the
exhaust manifold. Position 2-inch
wood blocks between the front sup-
port insulators and underbody side
members. Remove the jack and wood
block.
5. Bend the lock tabs and remove
the exhaust manifold lower retaining
bolts. Remove the safety stands and
lower the car.
6. Bend the lock tabs and remove
the exhaust manifold upper retaining
nuts, manifold(s) and gasket(s).
CLEANING AND INSPECTION
Refer to Part 8-1, Section 3 for
the cleaning and inspection proce-
dures.
INSTALLATION
1. Clean the surfaces of the ex-
haust
manifold ( s)
and
cylinder
head(s). Apply a light film of graph-
ite grease to the exhaust manifold
and cylinder head port areas.
2. Position
the
exhaust
mani-
fold(s) and gasket(s) to the cylinder
head(s). Install the lock tabs and
upper retaining nuts. Torque the re-
taining nuts to specifications and
bend the lock tabs.
3. Raise the car and install safety
stands. Install the lower retaining
bolts and lock tabs. Torque the re-
taining bolts to specifications and
bend the lock tabs.
4. Raise the front of the engine
and remove the wood blocks from
between the front support insulators
and underbody side members. Lower
the engine and install the front sup-
port insulator nuts and washers.
Torque the nuts to specifications.
5. Position
the
resonator
inlet
pipe(s) to the exhaust manifold(s)
and install the retaining nuts. Torque
the nuts to specifications.
6. Remove the safety stands and
lower the car. Remove the rear wheel
blocks and release the parking brake.
7. Start the engine and check for
exhaust leaks. Install the air cleaner
and air inlet duct assembly.
VALVE PUSH ROD
CHAMBER COVER
REMOVAL
1. Remove the high tension lead
wires from the coil
t~rminal.
Con-
nect an auxiliary starter switch to
the starter relay.
2. Position the No.
1
piston on
TDC of the compression stroke. Ob-
GROUP 8-ENGINE
serve the position of the distribu-
tor rotor.
3. Remove the intake manifold,
following the procedure under "In-
take Manifold Removal."
4. Remove the clamp securing the
distributor to the cylinder block.
Scribe a line on the distributor hous-
ing directly opposite the tip of the
rotor, for installation purpose.
5. Remove the distributor from
the cylinder block and valve push
rod chamber cover. Observe the
distance the rotor turns as the dis-
tributor is removed. This will be
very helpful when the distributor
is installed, for the mating teeth
of the helical gears will turn the
distributor shaft.
6. Clean the top of the valve push
rod chamber cover to prevent dirt
from falling into the chamber. Re-
move the cover.
INSTALLATION
1. Install a new gasket on the
valve push rod chamber cover. Use
an oil-resistant sealer on the gasket.
2. With the gasket in position,
lower the front of the cover into
position. Make certain that the rub-
ber grommet in the cover is not dis-
lodged by the distributor clamp stud.
Torque the mounting bolts to speci-
fications. Torque the center end
bolts first.
3. With the No.
1
piston on TDC
of the compression stroke, set the
distributor rotor in position to fire
No. 1 cylinder. (The rotor tip will
be aligned with the previously scribed
mark on the distributor housing.)
4. Turn the rotor counterclock-
wise a distance equal to the amount
observed during the distributor re-
moval procedure (approximately Vs
turn).
5. Install the distributor. The shaft
and rotor will turn clockwise as the
distributor gear meshes with the cam-
shaft gear. Check the position of the
rotor with the scribed mark on the
distributor housing.
6. If the installation is correct and
the distributor is properly seated,
install the distributor clamp, nut and
lock washer. Final timing of the
distrihutor must be made after
the engine is operating in the car.
7. Install the intake manifold, fol-
lowing the procedure under "Intake
Manifold InstaJiation."
8. Remove the auxiliary starter
switch and connect the high tension
lead wires at the coil terminal.

VALVE ROCKER ARM COVER
REMOVAL
1. Remove the air cleaner.
2. Disconnect the spark plug wires
at the spark plugs. Remove the wires
from the bracket on the valve rocker
arm cover(s) and position the wires
out of the way.
To remove the left rocker arm
cover, remove the air inlet duct as-
sembly from the exhaust manifold.
Move the heater hoses inward to al-
low room for removal of the rocker
arm cover.
3. Remove the valve rocker arm
cover(s) and gasket(s).
INSTALLATION
1. Clean the valve rocker arm
cover ( s) . Apply oil-resistant sealer
to one side of new cover gasket( s).
Lay the cemented side of the gask-
et(s) in place in the cover(s).
2. Position the cover(s) on the
cylinder head ( s) . Make sure the
gasket seats evenly all around the
head. Install the bolts (and the wire
loom clamps on the left cover) . The
cover is tightened in two steps. First,
torque the bolts to specifications.
Two minutes later, torque the bolts
to the same specifications.
If the left cover was removed, in-
stall the air inlet duct assembly.
3. Connect the spark plug wires.
Install the air cleaner.
VALVE ROCKER ARMS,
SHAFTS AND PUSH RODS
REMOVAL
1. Remove the valve rocker arm
cover(s), following the procedures
under "Valve Rocker Arm Cover
Removal."
2. Loosen the four rocker arm
support mounting bolts evenly and
alternately, two turns at a time, until
spring tension is removed. Remove
the mounting bolts and washers. Lift
the rocker arm assembly from the
cylinder head.
3. Remove the push rods from the
cylinder head. Index the push rods
to the bore from which they were
removed, for inspection and re-
placement purposes.
INSTALLATION
1. Lubricate each valve stem foot
and the rocker arm pad with Lubri-
plate.
2. Position the rocker arm and
