In2trux is right, I've seen those smoke testers over the years at a few shops too. I think they were made by Emtech or Emytech. My memory is fuzzy.

I've also seen where a shade tree mechanic took a coffee can and lit a cigar and used the smoke off the cigar to fill a motor to check for vacuum leaks.
