Review on 🚗 AutoLine Pro Automotive Smoke Machine Leak Detector EVAP Vacuum Diagnostic Tester - Shop Series - USA Made: Unbeatable Performance for Finding Leaks by Troy Houston

I'm NOT a mechanic. This smoke machine quickly proved it. After reassembling the upper/lower intake manifold on my 302, I found a vacuum leak that I couldn't find. After taking it apart twice, shouting out a few choice words my wife always loves, and throwing tools around the store, I ordered this smoke machine. I hooked it up and found that I didn't have a vacuum "leak" but a vacuum hurricane. So I broke down and actually read the manual, got the correct torque specs and assembled it correctly. Fog machine plugged in and the angels sang. If you're upset, yelling at your wife or throwing things you later regret, do yourself a favor and buy this or borrow mine, just take it somewhere. Welcome (this will make sense after you get the smoke machine and your stress level is down)
