Abstract: The invention is directed to a device for detecting cylinder leaks in an individual cylinder of an internal combustion engine having the cylinder head disassembled and wherein the piston in the tested cylinder is positioned at the bottom dead center and wherein a dual gauge leak-down tester is coupled to the herein disclosed device. The device has an internal airtight channel that allows pressurized air to enter from a pressurized air source to the device via a dual gauge leak-down tester and a set of clamps that acting as a security system, allows the user to firmly secure the device on the engine block. Once the device is assembled and secured above the cylinder and pressurized air is allowed to enter the cylinder through the device, leaks in the cylinder or its internal components are detected by comparing the percentage of air pressure indicated by each one of the gauges of the tester in a conventional manner.
