AutoLine Pro Automotive Smoke Machine for EVAP, Vacuum, Exhaust, and More Leak Detection Testing | Model 02 | Approved Smoke Fluid Included | Built-in Air Compressor | Pressure Gauge

Works great. I wish I’d bought it (or one like it years ago).

Compact, easy to use and essential to find stubborn and minute vacuum leaks in the engine intake systems; built-in low pressure compressor injects smoke throughout intakes. Favorably priced. Used baby oil in reservoir to generate great smoke stream.

Works great but needs psi boost. Adapted to its capabilities that’s why they sell a step up type!

Fast shipment, excellent piece of equipment, is it to use? A+++++++++ seller

Works as advertised and amazing! Found several leaks on customers cars!

I bought this little smoke machine and I didn’t expect much from it. Man was I surprised it works great.

The last time I had a vacuum leak it was my fault; there was a difficult-to-see vacuum hose I forgot to attach after I did some work. I eventually found the leak, but the whole time I thought how nice it might be to have a smoke machine. I tested this in the garage, not on a vehicle - it works. Not having used this kind of machine before, I felt a little underwhelmed at the amount of smoke produced. I added an empty plastic bottle hoping it might make it easier for the camera to capture. And to be fair, I could always see the smoke more easily than my cell phone seemed to capture. When I first turned it on there wasn't any smoke for a minute or two. It smoked for a few seconds then it seemed to stop all together, even though it had not been running anywhere near 5 minutes. So I turned it off, then back on as the instructions suggest and it worked better the second time. I did this 4-5 times over 20 minutes and the unit then smoked in a much more consistent manner. I didn't see anything in the instructions about needing any sort of "break in" period, but maybe it needed it. There still wasn't as much smoke as I thought there might be, but honestly if I had this connected to a car's vacuum lines I sure I'd see it coming out of any sort of leak. And maybe if it ran even longer it might produce a greater quantity of smoke - maybe. As is, I think this will work for me.

great small portable. affordable.
