16PCS Professional Diesel Engine Cylinder Compression Tester Tool Kit Set for Auto Tractor Semi with Case

I only used it once so far. It worked great. Other brands the complaint was about the poor threads on the adapters and the threads on this one all looked good.

This tester works really well. And has adapters to fit almost any engine. However unfortunately you may have to pull an injector instead of just a glow plug. Not a big deal for me since I bought it to use on salvage engines that are already out of a vehicle and I've already put on an engine stand. But be aware that especially for GM 6.2/6.5 you'll need to pull injectors instead of glow plugs.If I had to change anything about it. It would be the aforementioned lack of all glow plug adapters. And I would double the length of the hose. Otherthan those frankly not-picky things. It works quite well. Which is why it got 4 stars

Boi this thing saved my life great tool to have around

good product

The title is misleading by saying they have a gloplug adapter the right size to fit the 7.3 gloplug. This is correct! HOWEVER, it takes about 2-3 minutes to get it into the hole and threaded in as there is no clearance for a socket to be put on it between the rocker arm. If you fight it, and tighten it down all the way you can snug it with a needle nose in the air hole in the middle of the fitting, if you somehow got this far then you will realise that THERE IS NO ROOM TO CLIP ON THE GAUGE TO THE GLOPLUG ADAPTER. DO NOT, DO NOT, DO NOT, BUY THIS UNLESS YOU WANT TO BE FILLED WITH REGRET AND DISAPPOINTMENT. Have not tested on any other engine. Have a great day and spend your money elsewhere.

Gauge worked for a couple of tests and was pretty precise between readings, but I don’t have another one to compare it’s accuracy too. Second time I tried to use it the gauge failed to hold any pressure at all. This is after measuring no more than 450 of the supposed 1000 psi max on the gauge. The adapters are great and they fit both my Toyota diesels (3B and 3L) glow plug threads. This is one of cheapest diesel compression testers you can buy, and if you just want to get a quick idea of your engine readings it might be worth buying.

what a piece of junk. Used it once and now it does not work at all.

While it is a nice product it does not have a adapter to fit a Ford 6.0 powerstroke
