ABSTRACT:
A tool for engagement with overhead valves to retain them in securely raised positions while working on the valve associated structure to prevent valves from falling into the cylinder when released from such associated structure. The tool has a flexible tube with an inflatable balloon at one end thereof which is projected through a spark plug opening into the combustion chamber and a compressible bulb at the other end of the flexible tube for manually supplying air pressure to said balloon through the tube. The tool includes control valve means for selectively connecting the bulb directly to the balloon for inflating the latter in the combustion chamber to engage the valves and hold them in a raised position and for venting the tube to deflate the balloon and release the valves when the work is complete.
