How it works. This schematic shows the component parts of a typical leak-down tester. The gauge on the right is held at a standard pressure by adjusting the pressure regulator while the gauge on the left shows an example reading of 85-or 15% leakage.
Make sure the flywheel is secure. Using the quick-connect on the test hose, attach it to the leak down tester, this will pressurize the cylinder. Check that your regulator gauge still reads 100 psi and adjust if not. Subtract the cylinder pressure from 100. This is the percentage of leakage in your engine.
