How do you find a vacuum leak easily on a car? You use a smoke machine to introduce smoke into the vacuum system and look for visible signs of leakage coming from the engine. This is a great way to test any vacuum system on a car such as the evaporative emission system or the intake. This is just a basic look at how the smoke machine is used and what it is. Thanks everybody and we hope to see you on the Under The Hood Radio Show soon.
