In this video I show you how to use a very important automotive tool called a cylinder leak down test. I am able to identify a major failure in my BMW Z3 with M54 engine using the cylinder leakage tester.The purpose of a cylinder leakage tester, sometimes called a CLT tester for short, is to check for improper sealing of the combustion chamber. The cylinder leakage test is often performed in conjunction with a compression test to help identify engine problems.

Engine problems such as a misfire, poor running, stalling, check engine light all can be a result of poor compression or too high of an internal leak in the cylinder.
Leaks can occur due to BURNT VALVES, VALES NOT SEALING DUE TO BENDS, HEAD GASKET PROBLEMS.
