REMOVAL
1. Remove camshaft relating to valve oil seal to be removed. Refer to
EM-83, "Component".
2. Remove valve lifters. Refer to EM-83, "
Component".
3. Turn crankshaft until the cylinder requiring new oil seal s is at TDC. This will prevent valve from dropping
into cylinder.
4. Remove valve collet. Compress valve spring with the valve spring compressor, theattachment, the adapter (SST). Remove valve collet with a
magnet hand.
CAUTION:
When working, take care not to damage valve lifter holes.
5. Remove valve spring retainer, and valve spring.
6. Remove valve oil seal using the valve oil seal puller (SST).
INSTALLATION
1. Apply new engine oil on new valve oil seal joint and seal lip.
2. Using the valve oil seal drift (SST), press fit valve seal to height “H” shown in figure.
NOTE:
Dimension “H”: Height measured before valve spring seat instal-
lation
3. Install in the reverse order of removal after this step.

- Suitable drift: outer diameter 60 mm (2.36 in), inner diameter
50 mm (1.97 in).
Make sure the garter spring is in position and seal lips not inverted
CAUTION:
Be careful not to damage front timing chain case and
crankshaft.
Press-fit straight and avoid causing burrs or tilting oil
seal.

2. Release fuel pressure. Refer to
EC-87, "
Fuel Pressure Check".
3. Disconnect fuel pump fuse to avoid fuel injection during mea- surement.
4. Remove engine cover with power tool. Refer to EM-19, "

5. Remove ignition coil and spark plug from each cylinder. Refer to EM-42, "
Component" and EM-43, "Com-
ponent".
6. Connect engine tachometer (not required in use of CONSULT-III).
7. Install compression gauge with an adapter (commercial service tool) onto spark plug hole.
Use the adapter whose picking up end inserted to spark plughole 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.
