Valves and Springs



Invert the cylinder head, and number the valve faces front to rear, using a permanent felt-tip marker.

Using an appropriate valve spring compressor, compress the valve springs. Lift out the keepers with needlenosed pliers, release the compressor, and remove the valve, spring, and spring retainer. Clean the valve stem with lacquer thinner or a similar solvent to remove any gum and varnish. Clean the valve guides using solvent and an expanding wire-type valve book cleaner. Replace any parts that are damaged or worn.
