OTC 5605 Deluxe Compression Tester Kit with Carrying Case for Gasoline Engines

Best quality compression tester in my opinion. We got these at my auto school and I got sold real quick to buy this and the leak down tester.Great product overall you get accurate readings and it had all the adapters you need. don’t think twice on a quality item like this

works as described, has every adapter Ive ever needed

I have bought the cheap $30 compression test gauges and I can tell you, they don't work. Do NOT waste your money on cheap testing equipment. The cheap gauge i had before would read about 50-60 PSI on all 4 cylinders which I found strange considering it would run and idle fine. I spent hours diagnosing the problems that could cause the low compression. At first i thought it was the timing but all the timing marks lined up. Then I thought it could be the cylinder not sealing, so I bought a leak down kit. The leak down kit read about 10-15% on all 4 cylinders, which is acceptable on a 1980 Suzuki motorcycle. So after messing around for hours I finally gave up and bought this higher end compression test kit. I tested the cylinders with the new tester and BAM, all 4 were reading from 130-140 PSI. This is where I was expecting them to be. The moral of the story is NEVER buy cheap measuring equipment because you may be chasing your tail for no reason. Buy tools you can trust and count on.

Excelente calidad un producto muy recomendado
