Yes, they can be very useful, especially when the carb cleaner spray trick is hard to execute or for EVAP leaks. I don't know about that Chinese piece of crap. You used to be able to buy a machine made by Stinger for not much more than that. If you are creative you can make your own as well.

Anyone ever use a smoke leak detector tool?


I was wondering if they really can help you find a vacuum leak in an engine.

I have a smoke machine. They do work. They are a helpful tool in certain situations.
 
Bill Clinton used a cigar.
Homemade, jar contains 2 socks, bottle of baby oil and a soldering iron. bicycle pump to the white pen gives pressure.
End with glove fits over whatever you can fit it to, throttle body for example.
I use it while it in that box so it doesn't roll around or fall and break.

Out of business because their contrabulous fabtraptions do the same thing a cheap cigar does 😝 I don’t even smoke but that’s my go-to method for smoke tests.

I took an old empty bottle of 75W-90 and stuck a hose on the nozzle cap. Cigarette goes inside the cap. Then I punched a hole in the bottom and siliconed in a cheap PCV grommet and valve. Squeeze to smoke, release to "inflate" the bottle back.

That or I just stuck the cigarette in the line itself.

In what country?

A pack here is about $8 - $12 depending on where you buy them. That is one expensive habit.

If all you're doing is smoking an engine, you don't have to splurge on Marlboros. But that's why I love my pipe tobacco. A $5 ounce lasts me for weeks.

I can't argue with either of those statements. Nice work on the "smoke machine"!

I orginally asked about a smoke machine because Junkyard Digs was showing how they found a vacuum leak using a machine they got on Amazon. I started wondering if anyone else had used these. Then I was entertained with several "other ways" to get the same results.

What a site! Thanks guys.

The last time I used a smoke machine was over 20 years ago during Advanced engine diagnostics course in college. The machine they had took some time to get working - we would fill up the engines until the smoke was coming out of the exhaust pipes ( also useful for diagnosing exhaust leaks ).

In the very few times I've had to look for a vacuum leak - a cigar usually did the trick. One of my neighbors used this method to find a valve cover leak on his BMW recently, turned out to be missing a bolt.

I was considering buying one last year when my SS threw a lean code on both banks, until I noticed the evap fitting came loose from boost. 😉

Otherwise I wouldn't bother checking for vacuum leaks unless you have a related code.
