Automotive Smoke Machines

Leak detection machines for EVAP, intake, vacuum, exhaust, and boost leak checks.

Short answer: A smoke machine is best when the problem is a suspected vacuum, intake, boost, exhaust, or EVAP leak that needs to be made visible.

Leak-diagnosis references stress low pressure, calibration, adapters, stabilization time, and special care around EVAP systems.
