Cylinder Head Assembly

VALVES, VALVE SPRINGS AND VALVE SEALS INSTALLATION
1. Coat the valve stems with engine oil. Install the valves in the valve guides.

NOTE: Make sure the valves move up and down smoothly.

2. Install the spring seats on the cylinder head.





3. Install the valve seals using the valve guide seal installer.

NOTE: Exhaust and intake valve seals are not interchangeable.





4. Install the valve spring and valve retainer, then install the valve spring compressor. Compress the spring and install the valve keepers.

NOTE: Place the end of the valve spring with closely wound coils toward the cylinder head.





5. Lightly tap the end of each valve stem two or three times with the wooden handle of a hammer to ensure proper seating of the valve and valve keepers.

NOTE: Tap the valve stem only along its axis so you do not bend the stem.

CAMSHAFT, ROCKER ARMS AND CAMSHAFT SEAL/PULLEY INSTALLATION
1. Install the lost motion assemblies.





2. Install the rocker arms while passing the rocker arm shaft through the cylinder head.
- Valve adjusting locknuts should be loosened and adjusting screw backed off before installation.
- The component parts must be reinstalled in the original locations.

NOTE: Remove the rubber bands after installing the rocker arms.





3. Install the rocker shaft orifices. If the holes in the rocker arm shaft and cylinder head are not in line with each other, thread a 12 mm bolt into the rocker arm shaft and rotate the shaft.

NOTE:
- The shapes of the rocker shaft orifices for the intake and exhaust are different. The orifices must be installed in the original locations.
- Clean the rocker shaft orifices, and install them with new O-rings.





4. Install the VTEC solenoid valve and 20 mm sealing bolt.
