- Remove the 3 RH engine support insulator nuts, and only loosen the 3 LH engine support insulator nuts.
- Using the special tools, raise the engine.
- Depending on the valve being serviced, remove the LH or RH valve cover. For additional information, refer to VALVE COVER - LH or VALVE COVER - RH .
- Remove the spark plug. For additional information, refer to SPARK PLUGS .
- Rotate the crankshaft until the piston for the valve being serviced is at the top of its stroke with the intake valve and the exhaust valves closed.
- Using the special tool, compress the valve spring and remove the camshaft roller follower.
- Use compressed air in the cylinder being serviced to hold the valves in position.
- Apply a minimum of 965 kPa (140 psi) of compressed air into the cylinder.

All valve seals
CAUTION:
If the components are to be reinstalled, they must be installed in the same positions. Mark the components for installation into their original locations.
CAUTION:
If air pressure has forced the piston to the bottom of the cylinder, any loss of air pressure will allow the valve to fall into the cylinder. If air pressure must be removed, support the valve prior to removal.
CAUTION:
If the components are to be reinstalled, they must be installed in the same positions. Mark the components for installation into their original locations.
NOTE:
If a valve drops into the cylinder, remove the cylinder head. For additional information, refer to CYLINDER HEAD .
