The cylinder leak tester for gasoline engines is designed for quick and easy diagnosis of leaks in the combustion chamber. With this tester, you can check the degree of engine wear by supplying compressed air to the cylinder and determining the percentage of pressure loss due to cylinder leaks. It can detect issues such as piston ring damage, intake or exhaust valve damage, and head gasket damage. The device features a 100 psi (7 bar) pressure gauge and a cylinder leak indicator. It includes adapters for spark plugs: M12 x 1.25 and M14 x 1.5, as well as a hose with a quick coupling, and is packaged in a convenient case.
