Product Description

Stinger Automotive Smoke Machine - The #1 Solution for Engine Leaks

Stinger Smoke Hobo Automotive Smoke Machine is the best auto diagnostic tool you will ever have in your shop to find and fix car and truck vacuum leaks, evap system leaks, exhaust leaks, manifold leaks, etc. Stinger introduced the world's first fully portable no-compressor-needed pro automotive smoke machine vacuum leak tester in 2020. Innovating the perfect solution to tripping over bulky air hoses and being tied to your air compressor, Stinger's U.S.A.-made Smoke Hobo Smoke Machine was the first and is still the best built portable automotive smoke tester anywhere.

Stinger Automotive Smoke Machine with attachments

Not made from re-purposed paint sprayers or paper thin steel, Stinger uses super heavy duty housings and components - we welcome comparisons - feel free to view our photos which tell the tale. Stinger smoke machines are designed by aircraft mechanics and use aircraft-grade components and adhesives. Stinger excels in quality far above lesser quality machines - we will admit those machines have a very nice paint process with all the bright Yellows, Reds, and Blues they put out, but spending the extra dollars on a U.S.A built machine that focuses on quality and will likely outlast your shop versus a well-painted unit that lasts only a few smoke tests is always your best option.

Coupled with Stinger's long, heavy-duty fused power cord and vastly superior heating element, you'll instantly find your car or truck's vacuum leaks, manifold leaks, exhaust leaks, radiator leaks, etc. Since your Smoke Hobo is not tied down to a compressor's air hose, you can diagnose auto problems instantly, anywhere - not just at your auto shop or garage. Perfect for mobile mechanics and car shops. Just add oil and attach the battery clips to your car battery and that's it - you're making smoke and saving hours of time you used to spend tackling down leaks spraying carb cleaner under the hood or other far less effective methods which we mechanics have used for years - this is light-years better and you'll never go back to those methods.

Simple to use. Basic, with no useless features that will likely break in the future. Construction quality is excellent. Was producing massive amounts of smoke within seconds of hooking to battery and leak was quickly found by filler neck of gas tank. You will not be disappointed.

This is a quality unit at a super affordable price! I am just amazed honestly. Was not expecting this nice quality! So, off to how it works. So I did all the soaking of the wick and filling it up to the line they say to fill it to. Made sure the wick soaked for quite a while. Hooked it up to my compressor and a power 12v power supply in the garage. Waited for a few minutes and opened the valve and wow!!! Amazing smoke with perfect flow! I’m very impressed! Can’t wait to diagnose my evap issue this weekend!

It works just as advertised. I found it to make plenty of smoke and was able to identify my small leak in the EVAP system. For a DIY person like myself, it's ideal due to the low relative cost. If I were doing this type of work professionally, I would buy a better machine. My one criticism is the power cord. It is permanently attached to the oil reservoir and when you go to unscrew the reservoir to add oil, it's kind of a pain. The solution is to make the power cord detachable and that's what I did to mine.I cut the cord near the tank and then put a two conductor male plug on the smoker that you can buy at Home Depot for a couple of bucks. On the power cord I mounted the corresponding female plug. This modification makes screwing the oil reservoir on and off so much easier. It's cheap and easy to do, so I recommend this mod to anyone buying this machine.

What a great smoker, Period. Puts out more smoke than needed. But that's a great thing. This is professionally built and looks it. People complain about the smell. My wife said it's not any worse than my feet. Ha Ha very funny. All kidding aside it's well worth it.

Worked great spent $550 at a repair shop for plugs, spark plug wires, ignition coil and both oxygen sensors then told must be bad gas?? Researched engine codes everything pointed to vacuum leak. Used this machine found the leak in 3 minutes tops no joke

Great smoke machine! I got this to troubleshoot an engine lean code on my Land Rover LR3. It's made in California of high quality materials. Found a leaky o-ring on the PCV valve right away. Replacing o-rings is way cheaper than parts and taking the truck to the stealership!Happy customer!

This smoke machine works great. It's really solid and sturdy. Produces good smoke. The little 12volt pump it has is MUCH more convenient to use than a compressed air supply -- it's a low-power pump, exactly what works well with a smoke machine. I found it helped to include a clear plastic hose between the Stinger's hose and the engine so I could see the smoke flow. I first tried it on a car that had no vacuum leak, so I had to fake it by disconnecting vacuum lines in different places to see how it'll expose a leak. Fantastic! If there's a leak you can't see because your view is blocked by engine parts, you'll definitely see the smoke.

I'm an engineer, tinkerer, machinist, yadayada. I've been having a reoccurring issue with my 2008 Chevy truck and have put three canister purge valves on this truck (as well as vacuum solenoid and fuel tank pressure gauge) trying to throw rocks into the dark at this emissions code I keep getting. It turns out that I apparently keep getting really poor canister vent solenoid valves that don't work or fail quickly. This stinger smoke system works GREAT and put me on the faulty part right away. I wish I had bought it sooner. It's VERY well built - it's made from solid machined aluminum - and very much worth the investment. I'm a little surprised they can make it like they do at this price point and extremely happy with the performance.
