Description:
This tool is used when installing valve springs while the cylinder head is installed on the engine. This tool allows the combustion chamber/cylinder to be filled with compressed air, which holds the valve closed while the valve spring is exchanged. Simply place the cylinder you are working on at the top dead center, thread the tool into the spark plug hole, and fill the cylinder with compressed air. Just be sure to maintain the air pressure within the cylinder while performing the spring change.
