This cylinder leakage whistle identifies top dead center by sounding during the compression stroke and stopping once the piston reaches its peak position. It utilizes a quick coupler for direct connection to the cylinder hose, allowing for immediate integration into the testing setup. it also provides the timing accuracy necessary to remount distributors correctly during engine maintenance.
