What is a leak down test 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. Disconnect the gauge and move to the next cylinder A cylinder leak down test helps me assess internal engine health, isolate failing cylinders, and determine whether an engine needs a simple fix or a full rebuild. 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. Before you tear down the engine, pinpoint where problems are by using these three steps to do an engine leakdown test.
