Default Cheap smoke machine for vac leaks

Found this on the Garage Journal-
whole thread here- looks like it's worth considering, plenty cheap
probably needs a little fine tuning.

I've read on some boards that the party smoke machines use a water based liquid to generate smoke. Supposedly this is bad and only oil based smoke should be used. No idea if that's correct or not.

I was thinking of cobbling something together with smoke bombs meant for tossing into groundhog burrows...

i would like to see the article. I can only find details on how the oil product provides a better and longer smoke screen. To me, a what base would be safer for everyone including our cars. I guess the water could cause moisture inside the car, but once the car is started it would be gone. I am normally wrong on most things but anyways would like to see the article.

I bought this today. Tired of guessing if I'm fighting a vacuum or air leak.

20 years ago a handy tool to find "the leak", now its a waste of time not to replace all the seals as what isn't leaking today might start tomorrow.

Yup. Any small leak, might as well just pull the motor and do the head gaskets too.

Nice!
Too top shelf for me though. I went with one of these:
https://evapleakmachines.com/product...ection-economy
$69 on ebay. It has worked great for me, not only on P cars but on Hobie cat hulls, outrigger canoes, etc.
Personally I think this is a good way to go, as lots of times the leaks are in hoses, not seals, which are very expensive. Also, I have had leaks in hidden places, like this inside radius of a hose with a molded in bend where you would never see it. Plus even if you are replacing seals, you can only replace those you know about, and usually there are a few more. Only hassle is a tendency to leak baby oil on your stuff when you are not using it.

I made one of the "evapleakmachines" Cost about $20. Used an old BBQ regulator for 1.5 psi, an old paint can and some Nichrome wire. If you want to see a nice idea see this link.

Had a chance to use it today. Found a small leak where the vacuum line transitions to a larger ID as it runs to the fuel evaporator valve near the washer fluid neck.

@buccicone @Kevin in Atlanta
Where is the best place to attach the smoke output in the 32V engine?
MAF?

I placed the nozzle in the hose that runs to the DS intake manifold cover and plugged the hole.
