Cylinder Leak Down Tester Kit,Automotive Engine Pressure Gauges Compression Test Leakage Detector Tool Set - Black (TU-21)

Quick shipping, priced very well, does the job for the weekend mechanic!

Awesome !

Received the tool and it was leaking at a fitting. Very poor quality

Works well, but it takes some effort to get to the 'zero' reading. Usually I'll take 3-4 measurements to find the consistent value. Could be compressor, but I think its the unit. I'll turn the knob 5x and the needle doesn't move, then a very small turn and the needle launches from 30% to -20%. Usually when it does this the reading is off. If I get it to slowly move as I turn the knob it shows a consistent reading. So it works, fairly easy to use, just need to take a measurement more than once to verify accuracy.

Zeros at around 28 psi and it works great for the price you can't beat it and didn't have to pay a shop to do this who knows if the guy doing it knows what he's doingI was able to rule out internal issues with this tool, all the cylinders were within a few % of each other and that's what's important consistency that combined with perfect compression numbers tell me it's fine internally even at 200k

Building a Mk1 VW with a 1.8t 20V swap and I needed to check the health of the engine, I was a little nervous about the cost of this kit but it worked great. It helped located a few minor issues. Its one of those rarely used tools that is nice to have and at this price point I cant complain!

Can't wait to use it. Looks like good quality and the price was very fair.

The right gauge needle sticks making it near impossible to set. You can uncouple, bleed manually adjust the valve and recouple, until you find the right setting but then when you vent straight to atmosphere it won’t even move to the red area of the gauge. So an engine with no piston in theory would only have moderate leakage….This one is being returned. I’ll give China one more try, then I’m moving on

Hey, for this price it's pretty good!Not top quality but also a fraction of the cost of top quality.Used it on a snowblower that I suspected had a leak but it didn't.So as far as that goes it works very well.Case plastic is a bit on the cheap side but at least it has a case.I'd say it's well worth the cost.If I run into problems with it down the road I'll update this comment but so far so good!

este equipo viene sin ningun defecto y hace el trabajo como es descrito....lo recomiendo

Only used it once and it worked great. Only complaint would be the instructions say your air pressure can be between 50-100 but I could only zero the gauge if I had it at 100

Bought this to test my motorcyle, comes with easy to understand instructions. Delivery was very fast, and it did the job well

The media could not be loaded.  This product leaks from almost every connection, which in itself isn't the end of the world as it's nothing a little Teflon tape can't fix. If it was just this I would've given it 3 stars however both of the crimp fittings onto the 14mm hose were so poorly done that after threading it into my engine block they both started to spin. These started slipping at only hand tight and as they are now loose there is no easy way to get it back out of my engine block.I would definitely not recommend this product but if you do get it, check the fittings before installing it or if you are able re-crimp them prior to using.
