2. Slowly loosen the cylinder head bolts in the sequence shown in the illustration.








3. Using the spring compressor tool No. 09222-28000 and 09222-28100, or equivalents, remove the retainer locks.
4. Put these parts in order so they can be reinstalled in their original positions.



5. Remove the valve stem seals with pliers and discard them, then remove the spring seats.
NOTE: Do not reuse valve stem seals.


INSTALLATION
1. Install the spring seats.




2. Using the driver tool No. 09222-32100, or equivalent, lightly tap the seal into place.
NOTE: Do not reuse old valve stem seals.

CAUTION: Incorrect seal installation could result in oil leaking down the valve guides.

3. Apply engine oil to each valve. Insert valves into guides. Avoid forcing the valve into the seal. After installing the valve, check that it moves smoothly.




4. Valve springs should be installed with the enamel coated side toward the valve spring retainer.




5. Using the spring compressor tool No. 09222-28000 and 09222-28100, or equivalents, compress the spring and install the retainer locks.

NOTE:
- After installing the valves, ensure that the retainer locks are correctly in place before releasing the valve spring compressor.
- When the spring is compressed, check that the valve stem seal is not pressed against the bottom of the retainer.

6. Clean both gasket surfaces of the cylinder head and cylinder block.




7. Verify the identification marks on the cylinder head gasket.
8. Position the gasket surface with the identification mark towards the cylinder head.
NOTE: Do not apply sealant to these surfaces.

Fig. 14 Cylinder Head Bolt Tightening Sequence:

9. Using wrench tool No. 09221-32001, or equivalent and a suitable torque wrench tighten the cylinder head bolts in the sequence shown in the illustration to 105 - 115 Nm (1050 - 1150 kg. cm, 76 - 83 ft. lbs.).

NOTE: When tightening the cylinder head bolts, repeat the sequence 2 or 3 times, each time increasing the torque until the specified torque is reached.
