Most compression testers have a hose that has a quick connect air fitting on one end and the other end threads into the spark plug hole. You can use this hose to do a leak down test. You will need plugs for the intake and exhaust and an air compressor with regulator. Piston at bottom of the stroke and run no more than 6-8psi.
