In case anyone is wondering, a regular plastic tip Black & Mild cigar fits perfect in the orange hose. Cut off 2 inch section of the orange hose, stick it in the pump, then stick the cigar in the orange hose section
This needs to be the number one video for finding vacuum leaks. I’ve been having trouble with a rough running engine for so long and I’ve done everything from changing spark plugs and wires and taking it into a mechanic for diagnostics and it turns out with this little trick I have a huge vacuum leak out of my air intake. Thank you so much
I consider myself a TH-cam mechanic, thanks to all these guys willing to share their ideas and knowledge, i have opened my own repair shop, thank u all!

My friend you just saved me $150. Found the leak in about 30 seconds. This works GREAT!!! Thanks so much!!
I've seen about 10 of these so far, and this is the best one! Also can get a latex glove and put that over the throttle and then cut the finger off and then put the finger over the hose and then either tape pit or zip tie.
This is a great smoke machine! My 2000 Ford Ranger snorkel coming from the air box/filter(downstream of the MAF sensor) measures 3 1/4” inside diameter. I found that a foam beverage cooler presses in there nice and snug for a plug and already has a hole in the bottom to accept the smoker hose. Thank you!
You, Sir, hold the distinction of having invented the most illustrious vacuum leak detection device ever known to shade tree mechanics worldwide. I salute your genius! Cheap, readily available and easy, it amazingly checks all the boxes. And as far as I can tell, cars are immune to lung cancer last time I checked. I can now convincingly tell my spouse that the Cohiba panatelas are not for me but for her car. Thank you.
Thank you !Thank you ! Thank You! Save a whole mess of time and not to mention the money. Everything you used I had already in my tool box and garage . Found my leak . Happy to say mission accomplished.. 🤘🏻
Dude you're a freaking genius. I used this today to find not one but TWO EVAP leaks on my Jeep JKU. Only cost me 4 dollars for the cigars since I already had the pump. YOU ARE THE MAN!!!
This is the best idea ever. I did this and found the leak in 2 mins. I connected the line into the pcv valve line on my Chrysler Sebring and found the leak on the egr line. Thanks bro.
Bad ass video! With the cost of the pump, pcv valve elbow, and the cigar was under $11. Took me about 30 pumps to find my leak that was causing bank 1 and 2 lean codes. I owe you a beer for sure!
I have not tried this yet and hope it works for my 2010 camaro v6 BUT EVEN if it doesn't...THIS is a GREAT straight to the point and SIMPLE how to video!!!! Too many people are trying to become TuneStars and waist valuable minutes of your life with EXTRA UNNEEDED info ...BUT I digress. GREAT video my friend! : )
🤯🤯🤯🤯 I’m just speechless. All I need is the cap and nipple. My p0171 has been plaguing me for weeks. I hope that this helps me find a possible leak. Intake manifold gasket has been changed. So it might be a hose. Thank you !!!!
Awesome, can't thank any more! Cheap, easy and effective. With this video and some helpful comments, I eventually find a vacuum leak (from egr valve) that has been frustrating me for long. My 2cents input: 1) no need to go buy cigar, can make ur own with tea. Be sure to wrap tea bag paper in the end to avoid suck into the pump. 2) it might be hard to find exactly fit pvc cap and nipple in Homedepot. Just connect to anywhere else like brake boost line, and plug the intake air hose with a clean towel.
I used exactly this setup after watching the video, took 2 cigars to fill the whole intake, intercooler etc on my 944 turbo but the smoke got where it was supposed to go. getting it through the turbo was no problem. 3D printed an adapter to connect pump hose to J-boot.
Crazy thing is I have this pump and I have cigars so I literally had everything on hand, went out to try it on my jaguar xtype and found the leak within the first 2 minutes of pumping, thank you!
Great idea. I don't like the taste of cigars, since I don't smoke. I found a completely hidden crack in one of my rubber hoses that I would have never found thru normal visual inspection. Now I'm going to use this technique to find why the cheap briggs and stratton plastic carburetors are sucking air, and where it's leaking in. If your carburetor sucks air, it won't keep running after the initial start from priming, so this technique is useful for more than just your car.
I wish I had seen this months ago....can’t believe I let my truck sitting for so long due to frustrations of finding this leak. And thx for your extra tidbits and rationale e.g explaining why you place the piece precisely where you did, ways to get more smoke in manifold. Also, I was going to use an inscents cone , but I was worried that it would melt the plastic. The cigar is much better idea as there will be no contact between the plastic and the burning tobacco. My only concern would be a car that is gas fumey. Someone told me that fumes are ignitable. I guess all you’d have to do is light the cigar far away from engine in that case.
Amazing. When you're done you can also the cigar for a job well done 😄. I plan on trying this as well although I'm going to use an air compressor fitting so I don't have to keep pumping up the pump.
Good video. Actually more of an excellent video. Been chasing rough idle in my 'Taco for a long time. I suspect a cracked Plenum assembly that was replaced by the dealer. We will see. Thanks!
Thanks great idea it really works I covered the throttle body with a towel and connected the pump to my break release hose I found 2 leaks in my intake manifold
Going to try this on my C300 it has two lean codes. this cheap method will help me tack it down and see if I have any leaks and if not oh well it doesn’t hurt .. will give updates🧐👍. No leaks just had wet fuel injectors from a detail
Just a correction. Some leaks, particularly on booat pipes might not show without adding peessure to the system. I get many customers with tears which will be blocked until the pipe is pressurised and opens it up.
Just another tip...I used one of those plastic pumps that come with an exercise ball. Insert a lit cigarette into the inlet port, remover the shader-valve “T” connection and place the outlet tip of the pump into the vaccum line. Gently pump whilst watching that your cigarette doesn’t burn down. I find this method works best with 2 people. One to operate the pump and one to look for leaks. 😉 Hope this helps anyone on a budget. P.S., You may have to gently crease the cigarette filter to fit it into the pumps’ intake port. (*** I am not responsible should your vehicle develop a nicotine habit! ***) 😉
edredas LMAO! Yeah, just realized I made a typo. Meant to type Shrader-valve.. But just had to trace down a P0445 leak on an ‘04 Nissan Xterra....pain in the tailpipe! But with a little ingenuity, I came up with this tip seeing as how I had no smoke machine. Found YOUR video right after I found my leak! LOL
Wish I found this video a year ago. Been riding around with a bank one vacuum leak code since. Hopefully I can find what's needed to move this up with all your Corona vs going on.
What size pipe nipple should be used with this Multi-Use Transfer Pump at Harbor Freight, it specifies that its a 1/2" diameter hose. Should I purchase a 1/2" diameter or a 3/8" diameter pipe nipple to fit the 1/2" connecting hose used by this pump?
At first I thought this video was starring Ron Jeromie. Then I realized this is the easiest DIY smoke leak tester ever. Found my vacuum leak in about 5 seconds on my son's BMW. Great job!
In some cases you can turn the switch to ACC position, without starting the car and have someone press the accelerator to open it. If you have a push button start you can sometimes just press the button without your foot on the brake and it will go into accessory mode where you can press the accelerator to open it. I hope that helps!
Yes but due to all the extra plumbing you may find that using an air compressor with a regulator set to 5psi and spraying soapy water will work best for a boosted engine.
Get a latex glove and cut the finger off and then put the finger on top of the hose and use a zip tie or tape put the hand are bigger part over the throttle or air tube
@@itsme2369 I just found out that possibly the smoke can affect the mass air flow sensor which is usually right after the air filter so take take that out and then just cover it with some duct tape. I'm really excited about finding this video, because I already have that pump, however, all I have are Cuban cigars LOL
@@itsme2369 actually, we can just duct tape the hose right to the hole from the mass air flow sensor. It doesn't matter if there's a tiny bit of smoke that leaks out from the tape you can still look throughout the rest of the engine to find the other leaks. I have Gorilla Tape which is absolutely phenomenal if you've never heard of it
Someone asked this a while back and I wasn't really able to answer this since opening some manually can damage them while some have a manual override. So it would depend entirely on the car you're working on. Perhaps your owners manual may shed some light on the subject. I hope that helps!
Just have someone hold the throttle pedal all the way down while you're doing it or you could just use something heavy up against it to hold it down. Most cars these days open the throttle body even when the car is off when you just push the pedal down, you should be able to hear it open if you're quiet enough. If not, the put the car in the ON position but don't start it and try again.
I don't really smoke many cigars, but looking at a chart online the hole on the pump is about 12 -13 mm. So cross referencing it with the cigar gauge chart it should be a 0.19 or 0.2. I hope that helps!

Brilliant. This worked like a charm.... Best DIY video that saved a ton of money ive ever seen. Thank you
Damn this is by far the best version of a simple DIY one time use smoke machine
Wow! easiest smoke tester on all youtube hands down. Thanks!
Agreed. When I saw this vid after seeing many others I'm like and here's the winner!
Facts! This might be the greatest video in TH-cam history! WOW!

This takes Scotty's " cigar machine " to a new level . Simple and low pressure . Good tip to open the throttle body .
Clear and concise instructions. There's one not one extra seconds in this video that wasted anyone's time. Great job!
I bought a pump like that years ago and only used it once. Now I can put it to use...all I need is a cigar. Thanks for the video!

This is straight up mcguyver man. Im going to the hardware store right now!!!
Just made one, worked great. $7. for the pump, $8.50 for cheap cigars in town.
Number one smoke machine on TH-cam
Best DIY smoke test sofar. Thanks.
We are living in 2021. This guy is living in 3021. Brilliant!
Trying this method this weekend, thanks! Harbor Freight has this pump on sale right now for $3.50
Awesome!
This is the easiest way I used that pump once I was going to throw it away I'm glad I kept it
Just built mine this morning , will try it tomorrow
Great idea. Built one just like it and the smoker worked perfect . thanks for sharing .
Awesome glad it worked!
Thanks a million. I've got a leak so I'll be trying this very soon real soon. Once again Thanks. 👍😎
been needing to use up my case of Fuente Opus X , now I have a use for them!
Hi, my car has electronic throttle. How would I keep it open for the test? Thanks
Very good diy!! 👍🏻👏🏻😉 VERY clear & easy to understand.
Thanks!
Awesome! Great idea, I need to do this on my Mustang, it keeps kicking out a EVAP leak code. Thanks for video!
You just earned yourself a new subscriber Sir! outstanding. Thank you for sharing.
Awesome! Thanks!

I'm over here about to show my coworker about the smoker testing and behold this guy's is from Charlotte hell yeah........
wow dude!!! this is were Ron Jeremy requested the late George Burns for advice.. Awesome video bro
Amazing video what’s size is the pipe cap “ aproximación” length
I believe its a 2 1/2 pipe cap which is about about three inches in length. Thanks!
Did you find it?
You are great. No wasted time. Appreciated!

Can it test evap leaks ?
It’s possible but there is a risk that the fumes in fuel the evap system could cause a fire, so I don’t recommend.
Does engine need to be running?
The engine must be off for this to work.
How would you manage with an expectric Throttle body, that can't be accessed, cheers
In some cases you can turn the switch to ACC position, without starting the car and have someone press the accelerator to open it.

This maybe a stupid question.....
Do you test with the engine on

Will this work on boosted car?
Yes but due to all the extra plumbing you may find that using an air compressor with a regulator set to 5psi and spraying soapy water will work best for a boosted engine.
Dude thanks I was hoping I didn't have to buy a super expensive smoke machine
Link where you bought it
CIGAR!!!! Why didn't i think of that!!! Awesome!
I love the idea!
this is so much better than smoking the cigar which i have a hard time doing (wish i could but it just dont work out for me)
Shadyside! Hell yeah brother!
All I have to say is WOW! and Thank you!
What size is that pipe cap
I can't remember exactly but think it's a 2 1/2"
lovely! i already have a pump just like that one. just gotta hunt down a cigar! who knows, maybe a modified cigarette holder will work
It should! Good luck!
BRILLIANT! What size is the cap?

Clean that pile of leaves from your plenum!! They clog the drain and then water will overflow into HVAC blower when it rains.
What "ring gauge" cigar did you use for that little hand pump..?? Obviously, gars come in all sorts of diameters (ring gauges)
I don't really smoke many cigars, but looking at a chart online the hole on the pump is about 12 -13 mm. So cross referencing it with the cigar gauge chart it should be a 0.19 or 0.2. I hope that helps!
