Removal

CAUTION:
- Use fender covers to avoid damaging painted surfaces.
- To avoid damaging the cylinder head, wait until the engine coolant temperature drops below normal temperature before removing it.
- When handling a metal gasket, take care not to fold the gasket or damage the contact surface of the gasket.
- To avoid damage, unplug the wiring connectors carefully while holding the connector portion.

NOTE:
- Mark all wiring and hoses to avoid misconnection.
- Turn the crankshaft pulley so that the No. 1 piston is at top dead center.

Replacement

Valve Guide
1. Using the SST(09221-3F100A), remove the valve guide from the downside of the cylinder head assembly.




2. Reprocess the valve guide hole for the oversized valve guide newly installed.
3. Using the SST(09221-3F100A/B), insert the valve guide in the upside of the cylinder head assembly. Be aware of the difference in length between the intake and the exhaust valve guides.

Specification
Intake valve guide:
45.8 - 46.2mm(1.8031 - 1.8189in.)
Exhaust valve guide:
46.8 - 47.2mm(1.8425 - 1.8583in.)





4. After installing the valve guides, insert new valves and check the clearance between the valve stems and the valve guides.
5. After replacing the valve guides, check if they are properly installed with the valve seats. Reprocess valve seats if necessary.
