Removal and InstallationNBS003GI
REMOVAL
1. Remove engine cover with power tool. Refer to EM-19, "INTAKE MANIFOLD COLLECTOR" .
2. Remove ignition coil. Refer to EM-42, "
IGNITION COIL" .
3. Remove spark plug with a spark plug wrench (commercial ser- vice tool).
INSPECTION AFTER REMOVAL
Use the standard type spark plug for normal condition.
The hot type spark plug is suitable when fouling occurs with the standard type spark plug under conditions
such as:

Frequent engine starts

Low ambient temperatures
The cold type spark plug is suitable when spark knock occurs with the standard type spark plug under condi-
tions such as:

Extended highway driving

Frequent high engine revolution

14. Install front timing chain case as follows:
a. Apply a continuous bead of liquid gasket with the tube presser [SST: WS39930000 ( — )] to front timing chain case back
side as shown in the figure.
Use Genuine RTV Silicone Sealant or equivalent. Refer to
GI-48, "
RECOMMENDED CHEMICAL PRODUCTS AND
SEALANTS" .
b. Install front timing chain case as to fit its dowel pin hole together dowel pin on rear timing chain case.
c. Tighten mounting bolts to the specified torque in numerical order as shown in the figure.

There are two type of mounting bolts. Refer to the following
for locating bolts.
d. After all bolts are tightened, retighten them to the specified torque in numerical order shown in the figure.
CAUTION:
Be sure to wipe off any excessive liquid gasket leaking on surface mating with oil pan (upper).

CHECKING COMPRESSION PRESSURE
1. Warm up engine thoroughly. Then, stop it.
2. Release fuel pressure. Refer to EC-86, "
FUEL PRESSURE RELEASE" .
3. Disconnect fuel pump fuse to avoid fuel injection during mea- surement.
4. Remove engine cover with power tool. Refer to EM-19, "
INTAKE MANIFOLD COLLECTOR" .
5. Remove ignition coil and spark plug from each cylinder. Refer to EM-42, "
IGNITION COIL" and EM-43,
"SPARK PLUG (PLATINUM-TIPPED TYPE)" .
6. Connect engine tachometer (not required in use of CONSULT-II).
7. Install compression gauge with an adapter (commercial service tool) onto spark plug hole.

Use the adapter 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 cylinder head during removal.
8. Turn ignition switch to “START” for cranking. When the gauge pointer stabilizes, read the compression pressure and the engine rpm. Perform these steps to check each cylinder.
Compression pressure:
Unit: kPa (kg/cm2 , psi) /rpm
CAUTION:
Always use a fully changed battery to obtain the specified engine speed.

If the engine speed is out of the specified range, check battery liquid for proper gravity. Check the
engine speed again with normal battery gravity.

6. Remove valve oil seal using the valve oil seal puller (SST).
7. If valve seat must be replaced, refer to EM-110, "
VALVE SEAT REPLACEMENT" .
8. If valve guide must be replaced, refer to EM-109, "
VALVE GUIDE REPLACEMENT" .
9. Remove spark plug tube, as necessary.

Using a pliers, pull spark plug tube out of cylinder head.
CAUTION:

Take care not to damage cylinder head.

Once removed, spark plug tube will be deformed and cannot be reused. Do not remove it unless
absolutely necessary.
ASSEMBLY
1. When valve guide is removed, install it. Refer to EM-109, "VALVE GUIDE REPLACEMENT" .
2. When valve seat is removed, install it. Refer to EM-110, "
VALVE SEAT REPLACEMENT" .
3. Install new valve oil seals as follows:
a. Apply new engine oil on valve oil seal joint and seal lip.
b. Install with the valve oil seal drift (SST) to match dimension in the figure.
4. Install valve spring seat.
5. Install valve.

Larger diameter valves are for intake side.
NOTE:
Larger diameter valves are for intake side.
6. Install valve spring (uneven pitch type).

Install narrow pitch end (paint mark) to cylinder head side
(valve spring seat side).

Intake side and exhaust side valve springs are different.
Install them referring to the following paint mark collar.
7. Install valve spring retainer.
