had a problem with my sons 02 grand cherokee with a code PO442 evaporative emission control system small leak
been looking all over the thing off and on for the last few days I gave up went to a buddys shop picked he’s smoke machine
took me ten mins to find the problem It was a cracked vacuum hose for the purge valve on top of the gas tank To fix I had to drop the tank
There is NO way I would have ever found this with out this tool So I go and look for one and the one I just used is 1600 bucks
ARE THEY KIDDING ME :woohoo: Have looked all over and the cheapest i found was 950.00
In todays world this is a must have tool BUT there has to be a a good one at a affordable price
Don’t know if Eric has one but I just learned the hard way that this is one tool for todays cars that you just must have

It is really a must have tool for a shop. There is a backyard mechanic way of doing it but, it allows foreign fine particles into the engine which could damage the engine. I suggest you do not use this technique but, it is up to you. As a technician the only time I would do this is on a beater car aka a car you don’t care about and are just driving till it dies. https://www.youtube.com/watch?v=FFlyAqiYMro
What about buying a fog machine from a music store such as Guitar Center and do a little adapting so it can be used as an auto smoke detector. They’re way cheaper and do work.
A couple of years ago I saw one on a local Craigslist for 20 bucks and it even included a quart of chemical to make the fog.
