MANIFOLD-INTAKE
DIAGNOSIS AND TESTING
INTAKE MANIFOLD LEAKS
An intake manifold air leak is characterized by lower than normal manifoldvacuum, rough idle, or engine misfire.
WARNING: USE EXTREME CAUTION WHEN THE ENGINE IS OPERATING. DO NOT STAND IN ADIRECT LINE
WITH THE FAN. DO NOT PUT YOUR HANDS NEAR THE PULLEYS, BELT OR THE FAN. DO NOT WEAR
LOOSE CLOTHING.
1. Start the engine.
2. Spray a small stream of water (Spray Bottle) at the suspected leak area.
3. If engine RPM’S change, the area of the suspected leak has been found.
4. Repair as required.
REMOVAL
NOTE: Care must be taken to protect the intake
manifold powder coating from scrapes and abra-
sions.
1. Perform the fuel system pressure release proce-
dure,before attempting any repairs.(Refer to 14
- FUEL SYSTEM/FUEL DELIVERY - STANDARD
PROCEDURE - FUEL SYSTEM PRESSURE
RELEASE PROCEDURE).
2. Disconnect negative battery cable.

SPRINGS/SEALS-VALVE
DIAGNOSIS AND TESTING
VA LV E S P R I N G T E S T I N G
The valve springs should be tested whenever
removed for inspection, reconditioning, or replace-
ment.
1. Obtain specifications for spring tension at specified
spring length (Refer to 9 - ENGINE - SPECIFICA-
TIONS).
2. Turn table of Special Tool C-647 (2) until the sur-
face is in line with the spring length specification
mark on the threaded stud and the zero mark is on
the front.
3.Placespringoverstudonthetableandliftcom-
pressing lever to set tone device.
4. Pull on torque wrench (beam or dial type) until ping
is heard. Take reading on torque wrench at this
instant. Multiply this reading by two. This will give
the spring load at test length.
5. Compare reading to the specification. Discard the springs that do not meet specifications.
STANDARD PROCEDURE - VALVE SPRING/SEAL SERVICE IN-CAR
1. Disconnect negative battery cable.
2. Disconnect secondary ignition wires and remove
spark plugs.
3. Remove cylinder head cover(s) (Refer to 9 -
ENGINE/CYLINDER HEAD/CYLINDER HEAD
COVER(S) - REMOVAL).
4. Rotate crankshaft until No. 1 piston is at TDC on
compression stroke.
5. Remove rocker arms with pivots. The rocker arms
should not be disturbed and remain on pivot block.
6. With air hose attached to spark plug adapter
installed in No. 1 spark plug hole, apply 620.5 -
689 kPa (90 - 100 psi) air pressure. This is to hold
valves into place while servicing components.
CAUTION: Place a suitable shop towel around the
valve spring being serviced to prevent the valve
retaining locks from entering the engine once the
valve spring is compressed.
7. Using valve spring compressor MD998772-A with
insert 6716-A (1), compress valve spring (2) and
remove valve retaining locks.
8. Release valve spring compressor (1).
9. Remove valve spring and retainer.
10. Remove valve seal.
NOTE: Black valve seals are intake. Brown valve seals are exhaust.

11. The intake and exhaust valve stem seals should be pushed firmly and squarely over the valve guide using the
valve stem as guide. Push seal against top of guide. When installing the valve retainer locks, compress the
springonly enoughto install the locks.
CAUTION: Do not pinch seal between retainer and top of valve guide.
12. Follow the same procedure on the remaining 9 cylinders.Make sure piston is at TDC on the cylinder the
valve spring is being removed.
13. Remove spark plug adapter tool.
14. Install rocker arm and pedestal assemblies. Ensure push rods are seated properly under each rocker arm.

15. Install cylinder head covers (Refer to 9 - ENGINE/CYLINDER HEAD/CYLINDERHEADCOVER(S)-INSTAL-
LATION).
16. Install spark plugs and connect secondary ignition wires.
17. Connect negative battery cable.
REMOVAL
NOTE: Before replacing parts, inspect all related
valvetrain components for damage to prevent
engine misfire.
1. With the cylinder head removed, compress valve
springs using a valve spring compressor (1).
2. Remove valve retaining locks.
3. Slowly release valve spring compressor.
4. Remove valve spring retainer and valve spring.
5. Before removing the valves,remove any burrs
from valve stem lock grooves to prevent dam-
age to the valve guides.Identify the valves to
ensure installation in original location.
6. Remove valve seal.
7. Repeat procedure for remaining valves.
