EXHAUST MANIFOLD AND THREE WAY CATALYST
Revision: 2005 July 2005 FX
INSPECTION AFTER REMOVAL
Surface Distortion

Check the surface distortion of the each exhaust manifold flange
mating surface with straightedge and feeler gauge.

If it exceeds the limit, replace exhaust manifold.
INSTALLATION
Note the following, and install in the reverse order of removal.
Exhaust Manifold Gasket
Install exhaust manifold gasket with its directional protrusion set upward.
Refer to the figure of components on former page. Refer to EM-182, "
Removal and Installation" .
Exhaust Manifold

Install exhaust manifold and tighten mounting nuts in numerical
order as shown in the figure.
NOTE:
Tighten mounting nuts No. 1 to 4 in two steps. The numerical
order No. 9 to 12 shown second steps.
Heated Oxygen Sensor

Install heated oxygen sensors in the original position.

Install referring the following if the installation positions cannot
be identified.
*: The length of glass tube of bank 2 is longer than the one
of bank 1.
CAUTION:

Before installing a new heated oxygen sensor, clean
exhaust system threads using oxygen sensor thread
cleaner (commercial service tool: J-43897-18 or J-43897-12), and apply anti-seize lubricant (com-
mercial service tool).

Do not over torque heated oxygen sensor. Doing so may cause damage to the heated oxygen sen-
sor, resulting in “MIL” coming on. Limit : 0.3 mm (0.012 in)

SPARK PLUG (PLATINUM-TIPPED TYPE)PFP:22401
ComponentsABS00DFS
Removal and InstallationABS006IG
REMOVAL
1. Remove engine cover with power tool. Refer to EM-172, "ENGINE ROOM COVER" .
2. Remove ignition coil. Refer to EM-189, "
IGNITION COIL" .
3. Remove spark plug with spark plug wrench (commercial service tool).
CAUTION:
Do not drop or shock it.
INSPECTION AFTER REMOVAL
Use standard type spark plug for normal condition.
Hot type spark plug is suitable when fouling occurs with standard type spark plug under conditions such as:

Frequent engine starts

Low ambient temperatures
Cold type spark plug is suitable when spark plug knock occurs with standard type spark plug under conditions
such as:

Extended highway driving

Frequent high engine revolution
1. Ignition coil 2. Spark plug

TIMING CHAIN
Revision: 2005 July 2005 FX
7. Install oil pump drive spacer as follows:
a. Insert oil pump drive spacer according to the directions of crank- shaft key and the two flat surfaces of oil pump inner rotor.

If the positional relationship does not allow the insertion,
rotate oil pump inner rotor with a finger to allow spacer.
b. After confirming that the position of each part is in correct condi- tion to allow for spacer, force fit spacer by lightly tapping with
plastic hammer until it contacts and does not go further.
8. Install front oil seal on front cover.

Apply new engine oil to both oil seal lip and dust seal lip.

Install it so that each seal lip is oriented as shown in the fig-
ure.
CAUTION:
Be careful not to scratch or make burrs on circumference
of oil seal.

Using front oil seal drift (commercial service tool), press fit
until the height of front oil seal is level with the mounting sur-
face.

Make sure the garter spring is in position and seal lips not
inverted.
9. Install chain tensioner cover to front cover.

Apply a continuous bead of liquid gasket with tube presser
[SST: WS39930000 ( — )] to front cover as shown in the
figure.
Use Genuine RTV Silicone Sealant or equivalent. Refer to
GI-48, "
RECOMMENDED CHEMICAL PRODUCTS AND
SEALANTS" .
10. Install front cover as follows:

OIL SEAL
Revision: 2005 July 2005 FX

Using rear oil seal drift (commercial service tool), press fit
until the height of front oil seal is level with the mounting sur-
face.

Make sure the garter spring is in position and seal lips not
inverted.
CAUTION:

Be careful not to damage crankshaft and rear oil seal
retainer.

Press fit straight and avoid causing burrs or tilting oil seal.
3. Install in the reverse order of removal. Rear oil seal drift
Outer diameter : 102 mm (4.02 in)
Inner diameter : 86 mm (3.39 in)

CHECKING COMPRESSION PRESSURE
1. Warm up engine thoroughly. Then, stop it.
2. Release fuel pressure. Refer to EC-789, "
FUEL PRESSURE RELEASE" .
a. Remove fuel pump fuse to avoid fuel injection during measure- ment.
3. Remove engine cover with power tool. Refer to EM-172, "
ENGINE ROOM COVER" .
4. Remove ignition coil and spark plug from each cylinder. Refer to EM-189, "
IGNITION COIL" and EM-190,
"SPARK PLUG (PLATINUM-TIPPED TYPE)" .
5. Connect engine tachometer (not required in use of CONSULT-II).
6. Install compression gauge with adapter (SST or commercial ser- vice tool) onto spark plug hole.

Use compression gauge adapter (SST) which is required on
No. 7 and 8 cylinders.

Use compression gauge adapter (if no SST is used) whose
picking up end inserted to spark plug hole is smaller than 20
mm (0.79 in) in diameter. Otherwise, it may be caught by cyl-
inder head during removal.
7. With accelerator pedal fully depressed, turn ignition switch to “START” for cranking. When the gauge pointer stabilizes, read the compression pressure and engine rpm. Perform these steps to check each cyl-
inder.
Compression pressure:
Unit: kPa (kg/cm2 , psi) /rpm
CAUTION:
Always use a fully changed battery to obtain the specified engine speed.
