DIY Stop using carb clean for vaccum leaks!! Here is a alternative
 

Build this smoke machine for under $30 and be able to find vaccum leaks the correct way!! Carb clean will not show most vaccum leaks, this will help you find those very small vaccum leaks!! This inert smoke will fill the intake and leak out the smallest leaks, indicating where you have an issue. This is the only way to properly find a vaccum leak!! Our profesional machines work better. However most of you DIY's do not have the money to drop on the tools that we use. But this will get you close!!

Seth, are you saying this going into the intake and leaks outs(not that you fill the engine compartment and look for it to go in right?) Also what's with the diesel glow plug?

Yup goes into an intake use or intake inlet. Glow plug must be powered up to burn the fluid causing the smoke.

Most people who drive bmws have no clue what a vaccume leak is let alone what to do with this tool. Its sad but true. Thanks for the info

okay so attach 12 volt source to glow plug. lol i get it now.

I think i might be the type to go to spencers and get a smoke machine for 30 dollars.

thank you so much though. This is pretty smart :D

the smoke machine spensors uses will not put enough pressure out and do this job as needed. also not sure what they use for smoke, I know thi is safe to put into your car!!

I would tend to agree but I get auffly tired of hearing spray it with carb cleaner to find the leak!! So I made this post to inform peopl of the right way and proper way wiether they use it or not I can stop answering questions on how to find small leaks

huh - nifty! Definitely sounds like a useful tool - done my share of trying to find vac leaks with carb cleaner, always a pain.

Brilliant tool idea! Thanks for the picture and post.

Hey, you got any pics of an actual diy machine like this? Im trying to get ideas of how to what kinds of parts and how to connect.

i really hope someone didnt copy this guys idea and made those...

how about the propane method?

what do you mean? :hmm: The OP didnt come up with the concept of a smoking vacuum leak detector. What he drew out was just a schematic of the basic things you need to make one yourself. Every commercial smoking vacuum detector is based around the same basic parts...a low pressurized air source to force the smoke into the engine, some way to regulate it, a way to generate engine component/sensor safe smoke and the plumbing to hook it all together and to the engine...

oh ok my bad....

Went to the local Lowes and they didn't have squat as far as metal containers go (steel or aluminum)...

Any recommendations on where to go? I am definitely going to build one and put up a DIY!

probably could use something food or something comes it...check wally world lol

Dood! get creative :) If I were going to do this, I would try to find a hand held pesticide or weedkiller sprayer with a metal can, put a glowplug through the bottom with a nice gasket or petroleum proof sealant and replumb the pickup tube in the metal resevoir so you are only sucking out the smoke you are generating. This way you dont have to worry about electric pumps and extra plumbing. Just make sure the sprayer you get has a high enough pressure to force the smoke through the whole engine. I would imagine 10psi is more than enough. Good luck :thumbsup:

what is the method DEALERSHIPS use to find vaccuum leaks?

seth you should start making a couple of these and selling them here

They use commercially available smoke machines.
