DAYUAN 17 pc Diesel Engine Compression Tester Kit Tool Set Automotive Compressor

Worked very well , confirmed to me compression was good so not to scrap engine. Would not fit injector position on my Mitsubishi l200 but fitted the glow plug hole . AAA

Great tool great quality

Good solid piece of kit all contained in a quality plastic case. There aren't really any instructions, just a list of the parts and various warnings. This is annoying as it gives no idea of what some of the contents are for or how you use them. It is worth mentioning that this kit is deigned for a Truck (as it says on the leaflet) and none of the glow plug adaptors fitted my BMC engine which surprised me as it was a much used engine in it's day (Taxi etc). That said it did work through an injector. Worked fine and diagnosed what I suspected that one of the cylinders is down on compression.

Works perfect

Does what it’s named for great value for money easy to use and great accuracy

Did exactly what it's meant to

Although I purchased mine two years ago, only now did I get to use it. Positive results on first cylinder, pressed the button to release air pressure. Following cylinders all "leaked" through the air valve so gave results that were hard to gauge and wouldn't "stick" on the display. Rubbish quality.

It's ok does what should not always sometimes pressure release button sticks but corrects after a couple of pushes

Ottimo!!

Very nice machine

Funciona bem

Works perfect lots of accessories Recomended

Terrific case with a wide variety of tools to work on diesel engines at a very affordble price.
