A cylinder leak down test requires the removal of all the spark plugs. Instead of measuring the engines ability to create pressure compressed air is introduced into the cylinder through the spark plug hole. Consequently good cylinder leakdown readings should be below 5 8. 31 comes with 12mm and 14mm fittings and must be calibrated before each use by manipulating the schrader valve for the regulator.
It will have two gauges one with air pressure and one with leakage and an adj. It is also important to note this type of tester is not rated to measure more than 100 psi.
