should not be disassembled to determine the
cause of low compression unless some malfunc-
tion is present.
(11) Clean or replace spark plugs as necessary and
adjust gap as specified in Group 8, Electrical.
Tighten to specifications.
(12) Test resistance of spark plug cables. Refer to
Group 8, Electrical Ignition System Secondary Cir-
cuit Inspection.
(13) Test coil output voltage, primary and second-
ary resistance. Replace parts as necessary. Refer to
Group 8, Electrical Ignition System.
(14) Check fuel pump pressure at idle and differ-
ent RPM ranges. Refer to Group 14, Fuel System for
Specifications.
(15) The air filter elements should be replaced as
specified in Group 0, Lubrication and Maintenance.
(16) Inspect crankcase ventilation system as out
lined in Group 0, Lubrication and Maintenance. For
emission controls see Group 25, Emission Controls
for service procedures.
(17) Inspect and adjust accessory belt drives refer-
ring to Group 7, Cooling System, Accessory Drive
Belts for proper adjustments.
(18) Road test vehicle as a final test.
CYLINDER COMBUSTION PRESSURE LEAKAGE
TEST
The combustion pressure leakage test provides an
accurate means for determining engine condition.
Combustion pressure leakage testing will detect:
²Exhaust and intake valve leaks (improper seat-
ing).
²Leaks between adjacent cylinders or into water
jacket.
²Any causes for combustion/compression pressure
loss.
WARNING: DO NOT REMOVE THE RADIATOR CAP
WITH THE SYSTEM HOT AND UNDER PRESSURE
BECAUSE SERIOUS BURNS FROM COOLANT CAN
OCCUR.
Check the coolant level and fill as required. DO
NOT install the radiator cap.
Start and operate the engine until it attains nor-
mal operating temperature, then turn the engine
OFF.
Clean spark plug recesses with compressed air.
Remove the spark plugs.
Remove the oil filler cap.
Remove the air cleaner.
Calibrate the tester according to the manufactur-
er's instructions. The shop air source for testing
should maintain 483 kPa (70 psi) minimum, 1,379kPa (200 psi) maximum, with 552 kPa (80 psi) rec-
ommended.
Perform the test procedures on each cylinder
according to the tester manufacturer's instructions.
While testing, listen for pressurized air escaping
through the throttle body, tailpipe and oil filler cap
opening. Check for bubbles in the radiator coolant.
All gauge pressure indications should be equal,
with no more than 25% leakage per cylinder.
FOR EXAMPLE:At 552 kPa (80 psi) input pres-
sure, a minimum of 414 kPa (60 psi) should be main-
tained in the cylinder.
LASH ADJUSTER (TAPPET) NOISE DIAGNOSIS
A tappet-like noise may be produced from several
items. Check the following items.
(1) Engine oil level too high or too low. This may
cause aerated oil to enter the adjusters and cause
them to be spongy.
(2) Insufficient running time after rebuilding cylin-
der head. Low speed running up to 1 hour may be
required.
(3) During this time, turn engine off and let set for
a few minutes before restarting. Repeat this several
times after engine has reached normal operating
temperature.
(4) Low oil pressure.
(5) The oil restrictor pressed into the vertical oil
passage to the cylinder head is plugged with debris.
(6) Air ingested into oil due to broken or cracked
oil pump pick up.
(7) Worn valve guides.
(8) Rocker arm ears contacting valve spring
retainer.
(9) Rocker arm loose, adjuster stuck or at maxi-
mum extension and still leaves lash in the system.
(10) Faulty lash adjuster.
a. Check lash adjusters for sponginess while
installed in cylinder head. Depress part of rocker
arm over adjuster. Normal adjusters should feel very
firm. Spongy adjusters can be bottomed out easily.
b. Remove suspected rocker arms (sohc) or lash
adjuster (dohc) and replace.
ENGINE OIL LEAK INSPECTION
Begin with a thorough visual inspection of the
engine, particularly at the area of the suspected leak.
If an oil leak source is not readily identifiable, the
following steps should be followed:
(1) Do not clean or degrease the engine at this
time because some solvents may cause rubber to
swell, temporarily stopping the leak.
(2) Add an oil soluble dye (use as recommended by
manufacturer). Start the engine and let idle for
approximately 15 minutes. Check the oil dipstick to
PLENGINE 9 - 9
DIAGNOSIS AND TESTING (Continued)

CRANKSHAFT
A nodular cast iron crankshaft is used. The engine
has five main bearings. The number three main is
flanged to control thrust. The mains and connecting
rod journals have undercut fillet radiuses that are
deep rolled for added strength. To optimize bearing
loading, eight counterweights are used. Hydrody-
namic seals provide end sealing, where the crank-
shaft exits the block. Anaerobic gasket material is
used for parting line sealing. A sintered iron timing
belt sprocket is mounted on the crankshaft nose. This
sprocket transmits crankshaft movement, via timing
belt to the camshaft sprocket providing timed valve
actuation.
PISTONS
The engineDOES NOThave provision for a free
wheeling valve train. Non free wheeling valve train
means, in the event of a broken timing belt pistons
will contact the valves. The engine uses pressed-in
piston pins to attach forged powdered metal connect-
ing rods. The connecting rods are a cracked cap
design and are not repairable. Hex head cap screw
are used to provide alignment and durability in the
assembly. Pistons and connecting rods are serviced as
an assembly.
PISTON RINGS
The piston rings include a molybdenum faced top
ring for reliable compression sealing and a taper
faced intermediate ring for additional cylinder pres-
sure control. Oil Control Ring Package consist of two
steel rails and an expander spacer.
CYLINDER HEAD
The aluminum cylinder head features a Single
Over Head Camshaft (SOHC), four-valves per cylin-
der, cross flow design. The valves are arranged in
two inline banks, with the two intake per cylinder
facing toward the radiator. The exhaust valves facing
toward the dash panel. Rocker arm shafts mount
directly to the cylinder head. It incorporates powder
metal valve guides and seats. The hollow rocker arm
shafts supplies oil to the hydraulic lash adjusters,
camshaft and valve mechanisms.
CAMSHAFT
The nodular iron camshaft has five bearing jour-
nals and three cam lobes per cylinder. Provision for a
cam position sensor is provided on the camshaft at
the rear of cylinder head which also acts as thrust
plate. A hydrodynamic oil seal is used for oil control
at the front of the camshaft.
VALVES
Four valves per cylinder are actuated by roller
rocker arms/hydraulic lash adjusters assemblies
which pivot on rocker arm shafts. All valves have
chrome plated valve stems. Viton rubber valve stem
seals are integral with spring seats. Valve springs,
spring retainers, and locks are conventional design.
INTAKE MANIFOLD
The intake manifold is a molded plastic composi-
tion, attached to the cylinder head with five fasten-
ers. This long branch design enhances low and mid-
range torque.
EXHAUST MANIFOLD
The exhaust manifold is made of nodular cast iron
for strength and high temperatures. Exhaust gasses
exit the manifold into an articulated joint connection
and exhaust pipe.
COMPONENT REPLACEMENT

replaced:
²Camshaft
