How to Make a DIY Smoke Machine

In this video I make a quick backyard smoke machine and use it to find vacuum leaks on a 2004 F150 with a 4.2L engine. A smoke machine is a great tool to have, because sometimes a small vacuum leak is alot more tougher to find than one would imagine.

    I haven't done it, but I was wondering how a smoke bomb that you can get at your fireworks stands would work. Seems like it would be much safer than an open flame. I used to hold them in my hand as a kid. Plus you could use different colors and I would think that would be much more visible.

    Cool video! Thanks for the demonstration. Am about to make one, but i bought color smoke cakes from eBay. They are like smoke bombs. They should work well.

    Great video. If you made the tube from the air compressor extend to the bottom of the can it might keep the oil burning longer. The fresh air was probably bypassing the flame and not contributing to combustion.

    all you need is a cigar and a piece of hose ! blow cigar smoke through the hose and watch where the smoke comes out of and there's your vacuum leak !
