Homemade smoke tester to finding vacuum leaks in your car

The Pontiac Torrent has a P0401 check engine code for a small vacuum leak. Check out the homemade smoker I put together in order to see where the leak is coming from. I was able the find the leak and now I need to order more parts!

Definitely the best cheapest smoke machine I seen 💪🏽💪🏽 bout to build mines right now

Can you do a quick video of you lighting the cardboard up and showing that part of the process? I'm not quite seeing how this is simply not lighting on fire thus only charring with great smoke but not actually burning other than the air to heat ratio perse. This is greatness!

Another great way to produce the smoke in the jar is to soak an old sock or strips of a cotton T-shirt in mineral oil (baby oil works just fine) and wrap it around an old soldering iron or I've found that the heating element from an old hair dryer works great as well. This produces tons of smoke without the risk of blowing ashes into the system. It's important to keep the air pressure low too, around 1-2 psi, or you risk creating a leak or damaging components. Lastly, a rubber glove over the throttle body is a quick and easy way to seal it off. Thanks for video and helping people save money by trying to find and fix problems on their own. I think no matter what one's experience level or knowledge is about these things, it's generally good to at least do a little bit of research and at least try to understand what might be happening, rather than just blindly handing the problem over to someone else; a lot of times people pay a lot of money for very simple problems. With all the information that's out there and easily available this day and age, it'd be a shame not to use it. Thank you for your contribution.

Just make sure that the pressure doesn't go over 2 PSI because then then the pressure itself can cause a leak can cause a vacuum leak. However oh, thank you for making this video it's helped me alot

Very genius invention son I don’t think I’m gonna try it but it was a good idea😎

A much more simple way to smoke test is to buy a cheap AC / DC air pump (normally for filling air mattresses). They come with different size nozzles. The input side you use a cigar, the output a piece of hose to a vacuum line. Turn the pump on and watch for where the smoke comes out and there you are. Cost like $10-12. Works perfectly and it is instant.

You came up with a really good idea for creating and moving smoke, but if I were looking for an intake side leak I would want to include the duct between the air filter onward. The accordion section is notorious for splitting on some cars, and can cause havoc with the 02 sensors and air/fuel ratio

[walterbrob]

A couple of sticks of incense would work also

[dondale]

Tip: A plastic bag and a good size rubber band would close off that throttle body!!

[chuckychuck]

Hmm. Just use a small breville food smoker, that's what i uses, has a little fan on the back of it with two speed.

[theedifyingassembly]

Please do you mean. You put the ignition of the car ON, without starting it up in order to find the leak ?

[kgpcodes]

I found another video where the guy sprays water and uses a pump to fill the engine intakes with air. The car was not turned on. For me, that may be a good start. Then if it doesn't work, I will try this option.

Leaks are often easy to find if you have hypersensitive ears. But I don't. I do know there is a vacuum leak just by the sound of it but can't tell where using the method of just listening for leaks.

[dieselscience]

I don't see an update so I am assuming it was the EGR....
They _will fail__ the only question is how often.

[jamespn]

Looking forward to see if the replaced EGR solved you CEL and if you passed emissions inspection.

I never can subscribe to enough people that have good content. Thanks for the tip video.

Use a bright flashlight to shine on the small smoke leaks it will help see the smoke itself

[train]

Absolutely brilliant sir.steve ftom the uk.

[robertcrispell]

Jared give me a part number for this vac pump. I could not find it by googling walmart smoke detectors. thank you

[joaquinaguirre]

Great Mr. CarZ, really very good! thank you very much.

[jgbdseu]

Use what ya got! Awesome idea, thank you sir!
