AutoLine Pro Automotive *High Smoke Density* Smoke Machine Leak Detector EVAP Vacuum Diagnostics Tester | Economy Series | 1.2 Hrs Non-Stop Smoke for Each Single Test

After using it in my shop for a few weeks, I can say this machine is damn effective. You can be done with diagnosing leaks in mere minutes. What I found out that it does is turns mineral oil into thick smoke which is then pumped in sealed systems, such as air intakes, exhausts, you name it. Wherever there are cracks, smoke would seep out and this would determine the leak source.It's so effective and fast to use! To hook it up, you simply connect the power cables to the 12V positive and negative battery terminals of your car. Then plug in your air compressor and you're good to go. I now have 3 of these running, 2 in the shop and 1 at home. Huge time saver!PROS:- Fast and easy to use. Capable of finding common leaks in mere minutes. (Hint from experience: use a flashlight)- Works on almost all sealed systems like intake manifolds, exhausts, etc. and the mineral oil is safe for even oxygen sensors. Believe me, I've tried. However, I'd still cover up the mass air flow sensor just in case.- Has an air regulator @ a very safe 1 psi so your system doesn't blow out.- Compact. You can put everything back into the box it was shipped in for quick storage.CONS:- The unit requires mineral oil which is not included. Had to go out to purchase some at Walmart for a few bucks.- Air connector only allows for a quick connector fitting from any air compressor. But I don't see why you can't use a hand pump for this.- The kit doesn't include an EVAP port adapter, but you can simply disconnect the EVAP hose and use the included multi-size tip.If you have one in the shop, I'd recommend an EVAP port adapter for much faster diagnosing.UPDATE July 20, 2017: It's been 4 months since I've purchased 3 of these (2 in the shop and 1 at home). Everything is still working strongly. Quite impressive for such an affordable diagnostic machine. I refilled mineral oil only once or twice for the ones I had in the shop. Which costed me less than $3. Had a question about what type of mineral oil would be best and seller responded very promptly. Use plain ol' mineral oil guys! It's cheaper than baby oil and baby oil smells a little bit. Good customer service, great product. I'm happy, just thought I'd let you guys know.

I’ve been a mechanic for 61 years. I’ve never needed anything like this.. but after using it, I will never not have one. This one is a little crude. But it gets the job done. I’ll probably never use it again, but it was so damn fast. I found the problem in about 20 seconds. Very, very cool machine.!! I used it on my 2013 Jeep Wrangler 3.6 just a cool tool it doesn’t care what car you use it on. It would work on any kind. Been fighting the problem for a week and I found it in no time flat thanks so much for making such a neat machine.!!

Takes all of 2 minutes to connect everything. Instructions say it should take about 5 minutes before you start seeing smoke. It didn't take mine that long. I hooked it up to a 3 gallon air compressor from Harbor Freight, and gets consistent smoke. Worked like a charm.

I rated this as four stars instead of fiveonly because it is so cheesy looking. It literally looks like someone made it in their garage. The body of the machine is a 1 quart paint can and the air regulator used is one that would be found as a propane regularly on a propane grill. That being said the wires and all of the actual working parts seem to be of decent quality and this machine does work well and produces a good amount of smoke. I am a professional automotive technician so this will be used quite often so time will tell how well it holds up. However i am happy with the initial performance of it especially for $100. I just wish it wasn't so cheesy and homemade looking.

I failed to adhere to the one way directional flow of air supply, and support was prompt to help me resolve the issue, which was operator error, not the fault of the product. I made a suggestion to the company to be very clear about the directional flow of air supply. Otherwise a 5 star on instruction quality. Thanks for your world class support and excellent product. There are not enough companies that value customer service enough to care as you have shown. John Naisbitt said years ago that today’s competitive edge is “customer service”! He was correct then and now. As a business consultant, I could not agree more. I always go out of my way to promote and support companies like yours, companies that care and show it.

Wasn't expecting too much considering the price (90ish compared to $500+ for "pro" smoke testers)But it work good enough for most DIYersLots of smoke and fairly quick to "build up" smoke (about a min or so)I recommend the tip adapter kit because the metal cone tip this comes with isn't the best on some applications.ConsThe can gets HOT, so be careful where you place it.The smoke smell is pretty noticeable and lingers all more than it should IMO. Not a bad smell, similar to the old oil lamps but much stronger.

Only worked once and then the heating element no longer functioned.
