Valve Spring: Service and Repair

REMOVAL

NOTE: Identify valves and valve springs as they are removed so that each item can be reinstalled in its original position.

1. Using an appropriate sized socket and plastic mallet, lightly tap the valve retainer to loosen the valve deepers before installing the valve spring compressor.





2. Install the spring compressor. Compress spring and remove valve keeper.





3. Install the special tool as shown.





4. Remove the valve guide seal.





INSTALLATION
- When installing valves in the cylinder head, coat valve stems with oil before inserting them into valve guides, and make sure valves move up and down smoothly.





- When valves and springs are in place, lightly tap the end of each valve stem two or three times to ensure proper seating of valves and valve keepers (use plastic mallet).

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