Build a Smoke Machine for Under $10 | How to Smoke Test a Car | Check for Vacuum Leaks

I’ll just have my buddy who vapes blow in the tube

I think an aquarium air pump could be used to pump smoke

A fish tank air pump would work perfectly on this

I cannot get this to produce enough smoke.

So this might be a silly a question but is there a reason why no seems to use smoke bombs/tabs? I use them when testing the sewers I install but I never seen anyone suggest them for car vacuum leaks. What am I missing?

10$ I think your math is a little off...But since some things you would keep for further use, ill let it slide

👌💯

My issue is the music on this kinda of videos shouldn't be nothing but car noises

Can i use incenses?

Looks like something I made in highschool....

So I'm working out of an apartment and don't have access to an outlet. Is there either a safe way to use alligator clips to the battery, or to use a propane soldering iron?

Is that a bread tie on the air box 😂

what kind of oil do you use ? you said "Mineral" but I can't found anywhere baby mineral oil where I live in france. Thank you

Brilliant!

thanks man ...i pulled number 6 spark plug wire and heard a whitelisting noise, then the engine died on a old v6 taurus ........i can pull all the other wires and the engine wont die ....why does it keep dying on 6 and i hear the wistele right before it dies any ideas....

The mineral oil when getting hot creates an oily vapor which in turn , loosened the epoxy mountings... Just an fyi

Hey I see here people bashing you for the cost of things. Thanks Biden for that, but moving on if you have a spare tire well you have air pressure, go fill it at Costco for free with 40 PSI. Get a paper clip fold in half next take a bic cap and put hole dead center push paper clip to expose aprox 1/4 inch thru cap, now wind the extra clip wire around the cap. Now push it into the hose with the protruding paper clip to depress the tire valve in the hose aprox 5/16. Me I would loosen the valve with core remover but want to keep the cheapies satisfied and push into hose over air valve and now you have a somewhat air supply for free. If you do this when you get gas you can do it for free.

I will be trying this soon. Thanks for the video.

Thanks for the idea! I put one of these machines together and finally found my leak around the bottom of the throttle body. P0171 code fixed. Thanks

10 bucks, eh? a cheap bicycle pump is more than that by itself. still cheap... but not 10 bucks cheap.

If you would’ve just hooked up the hose to the intake manifold itself (like the pcv hose u pulled off and broke the pcv 😂)you won’t have to hold the throttle open manually.And I would actually pull the intake off and plug up the throttle body with a rag to get better results as u don’t really need to worry about leaks on the intake as much!

DO NOT apply more than 2-3 psi pressure to the evap system... pull all the vaccum u want. I like using a cheap 3$ aquarium pump (they are 1-2 psi) to induce smoke so I'm able to move around freely with 2 hands. I also recommend using a metal paint can with a handle rather than glass because iv had glass gars crack and break from the heat. Just some tips from some guy on the internet

Thank you! I had everything needed to make this except for the baby oil. I put it together, connected it to my evap system, plugged it in and WOW. Works amazingly well. Lots of smoke. Can’t believe how much smoke it produces. Thanks again!!!

I dig the funky tune!

My truck has a code for a leak but I tried starting fluid cant find the leak. The engine doesn't change at all when spraying it around the lines. My truck has these weird plastic lines and they don't make them any more. Each side is a different size and connect using rubber elbows so no idea how i can use standard hoses to replace them. One I glued back together with e 6000.

This works fine maybe add a Warning Disclaimer to the video example use a power strip with built-in fuse breaker and properly dispose of oil soaked rags to avoid changing Channel Name to Fire Hazard Garage 🔥 jk keep up Good Content!

so that was actually 80 bucks stomach ache machine, because the Pcv valve is probably 70 bucks itself already and the smoke smells like cats anaI tubes

damn i tried this and it did not quite work. Smoke was created indeed but it mostly came out of the soldering gun.

Is there any part of the soldering iron that is touching the rag? Or is it just to heat the air inside the jar?

Can I not use a vape and a hose to do the same progress

I have diy smoke machine, and it works fine. I'd like to be sure I understand the process -

Car off
Throttle plate open (a little? All the way?)
Cover air box (optional?)
Hook machine up to any single vacuum hose (brake booster?)

Did I leave anything out? Anything I got wrong?

Many thanks!

The only issue I have with mineral oil as a "smoke fuel" is not knowing how it will affect various sensors after coating them with that smoke. I like the idea of a fog machine, as it is water-based which is harmless as long as you're not going crazy on the smoke: just enough to get it done.

can i use glow plug instead of soldering iron ?

How to build it from the start..

Can I use heater core plug to heat the mineral oil?

I want to be 110% sure will the baby oil contaminate the gasoline and make it not ignite properly ???

Does the car need to be running? ..or in the on position?or just off?

Dang that’s pretty genius. Did you think of this yourself or do you wanna give some credit to someone else?

Bro thank you so much for this. I am about to try this 👍

pot heads getting crazy ideas! LOL

To prevent the smoke from coming out the air box I have seen mechanics pull the air cleaner hose off where it hooks to the Mass Air Flow Sensor. They then put a plastic grocery bag or garbage bag over the tube and then install the tube back on the Mass Air flow sensor.

That is definitely not a $10 smoker. Especially with that tubing lol. If someone is young and living in an apartment with nothing laying around the garage like most people have, I think they are looking at a $20-25 set up realistically

Found my evap leak immediately thank you for the advice good sir 👍

Does the soldering iron need to be touching the rags? Or just close?

Simple and straightforward, I like it.

Hello what is the safest way to store this after use since the rags are oil saturated?

Your pcv is leaking...

I thought this was gonna be a how to video to make something to smoke out other drivers on the road 🤣

i have a 09 toyota yaris , im seriously looking at my engine right now , i really dont know where to attach it too
