Inexpensive but works

After spending $1200+ to track down an EVAP system leak without success, I bought this smoke machine and found the issue in less than 5 minutes. Not a professional machine but it works!

Use baby oil

Product works like a charm. However I did not have any leaks so no pics to post. I tired mineral oil but it didn’t work as good and would keep blowing air instead of smoke. Switch to baby oil and it worked great !

Worked great.

I have been thinking I had a vacuum leak in my 2002 Chevy Silverado for 8 years. I was wrong. Worked great.

Finally arrived

I am getting ready to use and works just fine
