What is a leak down test Learn how to properly perform an engine cylinder leak down test like a pro to diagnose issues with engine performance and cylinder pressure. A leak down test is a method of using compressed air and a specialized gauge set that reads differential pressure to evaluate the condition of an engine's cylinders, pistons and rings, and valves and seats without disassembling the engine.

A cylinder leak down test is a diagnostic tool used to detect issues within a vehicle's engine cylinder by measuring how much air pressure is lost over time
It's crucial for pinpointing problems such as leaks in the piston rings, head gasket, or valves.
See the results, interpretations and tips for different leak paths and engine conditions. The overall point is that a leak down tester is a great diagnostic tool to identify real (or imagined) cylinder pressure difficulties But don't be alarmed if you get 15 to 18 percent leak down on. A cylinder leak down test, can tell you if the loss of compression is from, worn rings, burned or stuck open valves or a leaking head gasket.
A cylinder leak down test determines if the engine can hold pressure, which is necessary for proper and efficient combustion The goal of completing a leak down test is to determine what percentage of compression is lost within the cylinder. We discuss the whys and hows.
