ProkomonCylinder Leak Down Tester Kit, Gasoline Engine Compression Dual Gauge Leakdown Detector Tool Set for Pressure Check & Leakage Rate Test with Extension Rod

Todo muy bien tal cual como lo dice la descripción y dentro d ellos tiempos de entrega totalmente recomendado

Do NOT like the idea first calibrating to 100% - this applies to one and only one pressure setting.I bought the OTC, you can have any pressure, the ratio between the gauges is the percent leakdown.OTC has versatility because leakdown can be tested or a variety of input pressures, you need that to check leak consistency.This why I gave it two stars.However, unit works as advertised.But get the OTC...ciao,johnny.

It worked just as it was advertised and the case it came in was nice because it keeps all parts together.WEP.

I got it to test my race engine. Kit come complete and is so easy to used. This test together with checking compression gives the status of your engine inside.

A seperate quick release gauge on the manifold would have been more beneficial for a quick compression test or some quick release adaptor for another gauge. but, still, a very versatile compression tester.
