Blatant pitch...Leakdown tester was created by APE Jay


The Racetoolz dual gauge leakdown tester is a precision tool for measuring the amount of cylinder leakage in an engine. It will work on any internal combustion automotive or motorcycle engine with threaded spark plugs.

The tester requires an external air supply of at least 100 psi.

Simple to use. The adaptor hose screws into the spark plug hole and air supply is connected to the tool. The regulator is adjusted so the left gauge reads 100 psi. Any leakage is shown on the right gauge. If the right gauge reads 90 psi, that cylinder has 10% leakdown.

In most cases, the tester can pinpoint the leakage help diagnosis damage before the motor is disassembled. For instance, if leakdown shows on the gauge, listening at the exhaust outlet may product the sound of escaping air. This would indicate leaking exhaust valve/s. In the air intake, intake valves. Oil fill, leaking rings, etc.

Each leakdown tester comes with the precision measuring tool and one spark plug adaptor hose. Extra adaptor hoses as well as an extension hose is available.

Nice guage setup Jay. Why not just put a universal thread on the spark plug end and include 3 spark plug adapter sized that fit the universal thread?


Because on the newer motors like the busa, ZXs, etc, there is the risk of the hose unscrewing from the adapter and it would be in the head way down in the spark plug hole. :woohoo:
