Cylinder Leak-Down Tester & Compression Leakage Detector Kit

A compression test tells you something is wrong. A leak-down test tells you where. This tester pressurizes the cylinder and isolates the leak path, whether it is the rings, the valves or the head gasket.

Why you need it

Low compression has several causes and a standard gauge cannot tell them apart. Leakage testing shows how much is escaping and where it is going.
