mm (0.0008 in) (when manufactured at factory). Refer to EM-223, "
Standard and Limit".
5. Install the selected valve lifter.
6. Install camshaft. Refer to EM-166, "

of Valve Oil SealINFOID:0000000005398134
REMOVAL
1. Remove camshafts. Refer to EM-166, "Component".
2. Remove valve lifters. Refer to EM-166
.
3. Rotate crankshaft, and set piston whose valve oil seal is to be removed to TDC. This will prevent valve from dropping into cylinder.

When rotating crankshaft, be careful to avo id scarring front cover with timing chain.
4. Remove valve collet. • Compress valve spring using Tool, the attachment and the
adapter (A). Remove valve collet with a suitable magnet hand
(B).
CAUTION:
When working, be careful not to damage valve lifter holes.
5. Remove valve spring retainer, valve spring and valve spring seat.
6. Remove valve oil seal using Tool (A).
INSTALLATION
1. Apply new engine oil to valve oil seal joint surface and seal lip.
2. Press in valve oil seal to the height (H) shown using Tool (A).
3. Installation of the remaining components is in the reverse order of removal.

CYLINDER HEAD
• If the engine speed is out of the specified range, c
heck battery liquid for proper gravity. Check engine
speed again with normal battery gravity.
• If compression pressure is below minimum val ue, check valve clearances and parts associated with
combustion chamber (Valve, valve seat, piston, pi ston ring, cylinder bore, cylinder head, cylinder head
gasket). After the checking, measure the compression pressure again.
• If one cylinder has low compression pressure, pour small amount of engine oil into the spark plug hole
of the cylinder to re-check it for compression.
- If the added engine oil improves the compression, pi ston rings may be worn out or damaged. Check pis-
ton rings and replace if necessary.
- If the compression pressure remains at low level despite the addition of engine oil, valves may be mal- functioning. Check valves for damage. Repl ace valve or valve seat accordingly.
• If two adjacent cylinders have respectively low co mpression pressure and their compression remains
low even after the addition of engine oil, cylinder head gasket is leaking. In such a case, replace cylinder
head gasket.
9. After inspection is completed, install removed parts.
10. Start the engine, and confirm that the engine runs smoothly.
11. Perform trouble diagnosis. If DTC appears, erase it. Refer to EC-585, "
Trouble Diagnosis Introduction".
