bolts retain the radiator supply tank
mounting bracket and one bolt re-
tains the oil level dipstick tube brack-
et). Lift the manifold assemblies from
the head. Remove the gaskets and
sleeves.
6. To separate the manifolds, re-
move the air cleaner bracket and
remove the nuts and bolt joining the
intake and exhaust manifolds.
INSTALLATION
The manifold assemblies are shown
in Fig. 15.
1. Clean the gasket surfaces at the
REGULATOR VALVE
cylinder head and manifolds.
2. If the intake and exhaust mani-
folds have been separated, place the
intake manifold over the studs on the
exhaust manifold. Position the air
cleaner bracket to the exhaust mani-
fold. Install the lock washers, nuts
and bolt, then tighten them finger-
tight.
3. Install new intake manifold gas-
kets using new sleeves, if necessary,
in the ports of the cylinder head.
4. Place a new exhaust manifold
to muffler inlet pipe gasket over the
studs on the exhaust manifold.

5. Coat the mating surfaces lightly
with graphite grease. Place the mani-
fold assemblies in position against
the head. Make sure that none of the
gaskets have become dislodged. Posi-
tion the radiator supply tank bracket
and oil level dipstick tube bracket. In-
stall the attaching washers and bolts.
Torque the bolts to specifications,
tightening from the center to the
ends.
If the intake and exhaust manifolds
were separated, tighten the bolt and
nut joining them.
6. Install the exhaust manifold to
muffler inlet pipe lock washers and
nuts. Torque the nuts to specifica-
tions.
On an engine with positive crank-
case ventilation, install the exhaust
tube and regulator valve.
7. Connect the choke control
cable. Connect the fuel inlet line and
the distributor vacuum line at the
carburetor.
On a car with an automatic trans-
mission, install the accelerator re-
tracting spring bracket. Connect the
spring. Connect the accelerator as-
sembly connecting link and adjust the
transmission control linkage.
On a car with a manual-shift trans-
mission, connect the accelerator re-
tracting spring and the accelerator
rod assembly.
8. Install the air cleaner. Adjust
the engine idle speed and idle fuel
mixture.
EXHAUST GAS CONTROL
VALVE REPLACEMENT
The exhaust gas control valve (Fig.
3) is located in the outlet of the ex-
haust manifold. Normally, it does
not require replacement unless it be-
comes inoperative due to excessive
corrosion or damage.
1. Remove the manifold assem-
blies and separate the intake and ex-
haust manifolds following the pro-
cedures under "Manifold Removal."
2. Before removing the control
valve assembly, note the position of
the counterweight in relation to the
valve plate. Remove the stop spring
and thermostatic spring from the
front end of the shaft.
3. Using an acetylene torch in-
side the manifold, cut the shaft on
both sides of the valve plate. Use
caution to avoid damage to the shaft
bearing bores.
4. Remove the valve and shaft.
5. Clean the bushings of corro-
sion and repair any damage that may
have occurred. Replace the bushings
if necessary.
