2. Remove the fan, driv
e belts and water pump pul ley. Remove the valve
cover. Loosen the rocker arms and pivot them, then remove the
pushrods.

and measure the end clearance. T here should be 0.0015-0.0050 in.
(0.038-0.127mm) between the thrust plate and the camshaft.
If the clearance is less than 0.0015 in. (0 .038mm), replace the spacer ring; if
more than 0.0050 in. (0.127mm), replace the thrust ring.
11. Lubricate the camshaft, bearings, and lifters. Slide the camshaft
assembly into the engine and align the timing marks of the camshaft gear
and crankshaft gear.
12. Complete the installation by reversing the removal procedure.
V6 AND V8 ENGINES 1. Remove the engine from the vehicl e or remove all components from the
front of the engine (radi ator, grille, etc.).

3. Mark the distributor rotor, housi ng and engine block, then remove the
distributor. Remove the fuel pump and fuel pump pushrod on carbureted
engines.
4. Remove the intake manifold and valve covers. Loosen the rocker arms
and pivot out of way. Remove the pushrods and valve lifters.
5. Remove the oil pump drive.

ENGINE RECONDITIONING DETE RMINING ENGINE CONDITION
Anything that generates heat and/or friction will eventually burn or wear out (i.e.
a light bulb generates heat, therefore its life span is limited). With this in mind, a
running engine generates trem endous amounts of both; friction is encountered
by the moving and rotating parts inside the engine and heat is created b\
y
friction and combustion of the fuel. Ho wever, the engine has systems designed
to help reduce the effects of heat and fr iction and provide added longevity. The
oiling system reduces the amount of fr iction encountered by the moving parts
inside the engine, while the cooling system reduces heat created by friction and
combustion. If either system is not main tained, a break-down will be inevitable.
Therefore, you can see how regular main tenance can affect the service life of
your vehicle. If you do not drain, flush and refill your cooling system at the
proper intervals, deposits will begin to accumulate in the radiator, thereby
reducing the amount of heat it can extrac t from the coolant. The same applies to
your oil and filter; if it is not changed often enoug h it becomes laden with
contaminates and is unable to properly lubricate the engine. This increases
friction and wear.
There are a number of methods for evaluat ing the condition of your engine. A
compression test can reveal the condition of your pistons, piston rings, cylinder
bores, head gasket(s), valves and valve seat s. An oil pressure test can warn
you of possible engine bearing, or oil pump failures. Excessive oil consumption,
evidence of oil in the engine air intake area and/or bluish smoke from the tail
pipe may indicate worn piston rings, worn valve guides and/or valve seals. As a
general rule, an engine that uses no more than one quart of oil every 1000
miles is in good condi tion. Engines that use one quart of oil or more in less than
1000 miles should first be checked for oil leaks. If any oil leaks are present,
have them fixed before dete rmining how much oil is consumed by the engine,
especially if blue smoke is not visible at the tail pipe.
COMPRESSION TEST
A noticeable lack of engine power, excessive oil consumption and/or poor fuel
mileage measured over an extended period are all indicators of internal engine

THERMOSTATIC AIR CLEANER (THERMAC)
OPERATION
This system is designed to warm the air entering the carburetor when
underhood temperatures are low, and to ma intain a controlled air temperature
into the carburetor or throttle body at all times. By allowing preheated air to
enter, the amount of time t he choke is on is reduced, resulting in better fuel
economy and lower emissions. Engine warm-up time is also reduced.
The THERMAC system is composed of th e air cleaner body, a filter, sensor
unit, vacuum diaphragm, damper door, a ssociated hoses and connections. Heat
radiating from the exhaust manifold is tr apped by a heat stove and is ducted to
the air cleaner to supply heated air to t he carburetor or throttle body. A movable
door in the air cleaner case snorkel allows air to be drawn in from the heat stove
(cold operation). The door position is co ntrolled by the vacuum motor, which
receives intake manifold vacuum as modulated by the temperature sensor.
A vacuum door which remain s open can cause carburetor icing or poor cold
driveability. A door which remains clos ed during normal engine operating
temperatures can cause sluggishne ss, engine knocking and overheating.

On the 2.8L engine only, an anti-backfire (g
ulp) valve is used to allow air flow
into the intake manifold. This is us ed to help prevent backfire during high
vacuum deceleration conditions. The extra air enters the intake system to lean
the rich air/fuel mixture. The valve is o perated by the intake manifold vacuum to
allow air from the air filter to flow into the intake manifold.

TESTING
To determine if the pump is in good condition, tests for both volume and
pressure should be performed. The test s are made with the pump installed, the
engine at normal operating temperatur e and operating at idle speed. Never
replace a fuel pump without first performing these simple tests.
Ensure the fuel filter has been changed at the specified interval. If in doubt,
install a new filter first. Always check fo r broken or deteriorated fuel hoses. If a
line has a crack or split, the pump may be operating properly, but the pump will
only draw air, not fuel.
PRESSURE TEST
1. Disconnect the fuel line at the carburetor, then connect a fuel pump
pressure gauge. Ensure the carburet or float bowl has a sufficient amount
of gasoline.
2. Start the engine and c heck the pressure with the engine at idle. If the
pump has a vapor return hose, squeeze it off so that an accurate reading
can be obtained. Pressure should be 5
1/2-61/2 psi.
3. If the pressure is incorrect, replace t he pump. If it is within specifications,
go on to the volume test.
VOLUME TEST

REMOVAL & INSTALLATION
Always replace all internal gaskets that are removed. Flooding, stumble on
acceleration and other performance comp laints are in many instances, caused
by presence of dirt, water, or other foreign matter in carburetor. To aid in
diagnosis, carburetor should be carefully removed from engine without draining
fuel from bowl. Contents of fuel bowl may then be examined for contamination
as carburetor is disassembl ed. Check the fuel filter.
