Features
- Engine Cylinder Leakage Test: JIFETOR cylinder leak gauge set is designed to detect a variety of common engine faults including: worn piston rings, worn valves, cracks in cylinder walls and blown head gaskets. Available with either single gauge shows % of cylinder leakage, or twin gauge manifold show cylinder leakage and cylinder pressure. Suitable for any gasoline engine with 14, 12 or 10 millimetre spark plugs. The % gauge is a precise instrument, please handle it with care
- Working Principle of Leakdown Detector: Once the leakage tester has been connected to one of the cylinders, compressed air (45-100 pounds per square inch) is fed into that particular cylinder through the built in pressure regulator. Diagnosis is made by observing the amount of leakage that is indicated on the cylinder leakage gauge and by listening for leakage at various points of the cars system. Please note: This cylinder leak tester is not suitable for shallow cylinder
- Dual Pressure Gauges Assembly: There are American style air plug, pressure regulating valve, aluminum manifold body, cylinder pressure gauge, cylinder leakage gauge, 19 inch long rubber nylon resin hose with quick coupler on the assembly. The two gauges adopt rubber cover protected 3 inch large dial, the pressure gauge with scale range 0-100 pounds per square inch / 0-7 bar, and the leakage gauge with color coded range marked with HIGH MODERATE LOW SET
- 3 Adapters and Other Parts: There are 3 sizes adapters brass coated aluminum 14 millimetre (fixed on a 10 inch long hose), aluminum 12 and 10 millimetre (both can be connected to 14 millimetre adapter), can help to test the gasoline engine with 10 12 14 millimetre spark plug holes. The instruction has detailed introduces about notification, connection method, operation steps, fault diagnosis, please read it carefully first
- Detailed Product Manual and Case: The instructions in the package introduce the usage and precautions of the product in detail. Please read product manual carefully before operation, and always refer to equipment manufacturer's operation instruction, compare to the manufacturer's recommended readings. Customized blow molding case keeps JIFETOR engine cylinder leak down tester kit in place and protects the gauges during storage

I checked out reviews on many leakdown testers on Amazon and could not find one with consistently good ratings. I suspect that many of the poor ratings were due to mishandling of the device (it's easy to blow out 1 or both gauges if you don't follow the proper procedure) but there were also many seemingly legit complaints about flimsy parts and poor quality. I spotted this tester by jifitor, newly released and with 0 reviews. It was in the lower price range so I thought I'd take a shot and be the first one to review (you're welcome). This tester is everything i hoped it would be. The body is a nice solid chunk of metal and the gauges are good size with protective rubber sleeves over them. There is a quick connector for the air inlet that fit my compressor, although there are many different connectors and you may have to switch it. The hose and adapters for the spark plug hole fits both usual sizes for cars and also the smaller 10mm for motorcycles. Would have liked this hose to be a bit longer - might be a pain for big block v8's. One very good thing about this unit was the clear and comprehensive instructions. It clearly states the warning about turning the regulator on the unit to 0 before connecting the air line to avoid damage and it also shows a long list of possible causes of air escaping from different parts of your engine. If I had never used a LD tester before I believe I could have followed these instructions and had no trouble. Like everything made these days it comes in a blow-molded case (I have a tall stack of such cases in my garage) but anything with gauges should be kept in a case. Overall this is a perfect tester for a casual user or even a shop that might use it once or twice a week. The regulator knob is plastic and it might survive a drop or 2 but I wouldn't want to chance that. I fed in 95 psi from my compressor and it worked fine. In conclusion if you need a leakdown tester I would recommend this one. I just hope you have better luck with your engine than I did (air blowing out oil dipstick engine has to come out)

la indicación del, indicador que muestra la fuga del cilindro, no concuerda con las instrucciones de calibración (4.2.6). Es decir, que para que el indicador de fuga llegue a la condición SET 0, tengo que ingresar 100 psi. (prueba realizada sin estar conectado al cilindro). En todo caso NO devolveré el probador y comprare otro. (Lo encuentro bonito Jajajajaja). buen precio, buen vendedor y excelente tiempo de entrega.

I bought this to check out an engine that I had pulled to see if it was worth trying to sell. To use this, you have to set the pressure on the second gauge to zero without the hose going to the spark-plug connected to the quick connect. This took right at 100 psig. Then, with the piston at top dead center for firing and the spark-plug hose connected in the block, connect the spark plug hose to the quick connect. On my first cylinder, it had zero leakage. The rest were toast. Be aware that the pressure in the cylinder might cause it to rotate the crank if things are working properly. Eric the car guy has a video on it which provides insight into its use. Great tool for a great price.

I recently purchased a cylinder leak down tester kit and I am extremely disappointed with the product. The kit arrived with missing parts and the instructions were not clear and incomplete. The tester itself felt flimsy and cheap, and it didn't provide accurate results. The connections were also poorly designed and they leaked air, making it difficult to get accurate readings. I also found that the kit was not compatible with all types of engines and vehicles, which made it difficult to use on multiple vehicles. Overall, I would not recommend this cylinder leak down tester kit to anyone, it's a waste of money and time. I would advise looking for a different and more reliable product on the market.

This leakdown tester is exactly what I needed. It’s easy to use and includes great instructions. The fitting to attach to my shop air was the wrong design but it was easy to switch out. I used it to determine the leak location in my 01 Civic which turned out to be the rings. No guessing and throwing parts at a vehicle when you have the right testers.

Works pretty darn well to determine if your problem is a valve (and which valve) or piston/ring compression leakage. Pay attention to instructions. Use a pre-regulator to keep unit input pressures under 100 psi, that small leakage gauge is sensitive. And be sure the unit input pressure regulator is backed out to zero before connecting the input compressor air. We set our input air at 60-70 lbs, back the unit air adjustment all the way out to zero, apply air, set the leakage gauge to zero, connect to plug hole, then check for leakage behind intake, then exhaust valves. Piston leakage will come into the crankcase (or the water jackets/radiator if you have a bad head gasket or cracked block/head. New engines can have around 15% leakage overall. Color bands on leakage gauge for acceptable limits.

The leakdown tester seems to work alright HOWEVER if you use the 12" extension hose as the instructions recommend, you will not get an accurate reading. The orifice on the 12" hose is too small, even running a test (after calibrating the gauges) while not connected to a spark plug hole the gauge will not read 100% leakage. This can be seen in the attached picture. If you rig the tool together without the 12" extension the gauge seems accurate, and will show 100% leakage. So my take away is that this is a good tool, but the accessories need to be improved for accurate readings. And I would recommend not to use the 12" extension as this will skew your results.
