What Is A Leak Down Test On An Engine : Cylinder Leak-Down Test - Hemmings Motor News : What is an engine compression test?. But instead of measuring pressure, it measures pressure loss. When you do hold the crank become a pita. The procedure of operation depends on whether or not you have the cylinder head attached to the engine block or not. ¶ leak down testing is simply measuring the rate of air leakage past the rings and valves of an engine. Loss reading an engine leakdown test is a compression test in reverse.
I agree, how to perform an engine cylinder leak down test would be a better title. I got the leak down tester from harbor freight, and while i did eventually get it to work properly, there were a couple of issues.
