Valve Spring, Retainer, and Seal
Removal
NOTICE: During engine repair procedures, cleanliness is extremely important. Any foreign material, including any material created while cleaning gasket surfaces that enters the oil passages, coolant passages or the oil pan, can cause engine failure.
1. Remove the camshaft roller followers. For additional information, refer to Camshaft Roller Follower Camshaft Roller Follower.
2. NOTICE: If the components are to be reinstalled, they must be installed in their original positions or damage to the engine may occur. Mark the components for installation into their original locations.
NOTE: If air pressure has forced the piston to the bottom of the cylinder, any loss of air pressure will allow the valve(s) to fall into the cylinder. A rubber band, tape or string wrapped around the end of the valve stem will prevent this from happening.
NOTE: If a valve drops into the cylinder, remove the cylinder head. For additional information, refer Cylinder Head - RH Cylinder Head - RH or Cylinder Head - LH Cylinder Head - LH.
Pressurize the cylinder using compressed air.
3. Using the Valve Spring Compressor, remove the key, retainer and the valve spring.
4. NOTE: Camshaft removed for clarity.
