vacuum smoke thingy question
 

ok i got this idea,

like a smoke machine but way cheaper.

could you just fill a 2 liter jug with water and dry ice, then run a line from it to the TB and have a smoke machine to check for leaks.

figure the ice should make enough smoke cause if you cap the bottle it expands and explodes so obviously there is an excess gas produced.

but the question is, how much dry ice to create enough smoke to fill the intake manifold and come out any leaks?

like so, mad crazy paint skills.

sounds liek a dry ice bomb to me lol

Looks like an upside down portrait of Mr. Garrison to me.

I'm guessing that the dry ice wouldn't put off enough smoke to really show leaks, but it might work.

i see a crazy morphed sperm.. lol

dude check for leaks = turn car on and spray starter fluid along where you think its leaking.. if car dies down for a sec then thats your leak..

second.. buy a hookah (because it produces more smoke) or just smoke a cig.. turn car on and exhale on where you think its leaking.. watch smoke get sucked in?

chances are even if you have a vacume leak.. filling the intake with smoke wont show you the leaks.. vacume leaks usually are small.. and just because a vacume leak can suck in air doesnt mean it will let out smoke...

It's not going to work at all when the engine is running, there is less pressure in the intake than atmo so no smoke would come out of any leaks it would just get sucked into the engine. The only way it would work would be if you pressurized the intake system with it when all of the intake valves are closed. Also, CO2 gas is usually invisible unless you used a bunch of it. Nice idea for thinking differently but there are easier ways.

Re: vacuum smoke thingy question
 

like an just plug the throttle opening with a cap so it is air tight. and do a manual vacuum tester ot opposite and pressurize it just like a leak down test but alittle different

Re: vacuum smoke thingy question
 

Jesus christ I would hate to know what an inkblot test says about you.

lol

Re: vacuum smoke thingy question
 

Dry ice vaporizes into CO2 which is an inert (and thus oxygen displacing) gas. It would just kill the motor, like putting out a fire with a CO2 extingusher. :3




Dumb-ass :1

Re: vacuum smoke thingy question
 

ok, wow.

i thought i didnt know anything.

have any of you ever seen the device that pumps smoke into the intake manifold.

thus pressurizing it, then the smoke comes out the vacuum leaks.

i mean c'mon guys, are you all ------- retarded?

and who ever said this would be happening when the car is running.

that goes against the entire idea of checking for leaks.

if the engine is sucking air then the smoke would just be sucked into the engine.

idk, seems fairly simple to me. just cheaper than buying the actual machine.

typing errors aside i believe this is the only one of you who understands what im talking about

Re: vacuum smoke thingy question
 

ok dude

your diagram shows a pop bottle hooked up to the tb with dry ice/water to make smoke...
that will not pressurize the intake.. thqats the point i was trying to make

Re: vacuum smoke thingy question
 

ok

what happens when you put dry ice and water in a bottle and cap it?

it pressurizes the bottle, then bang, a dry ice bomb correct?

so now, do the same but dont cap the bottle, instead place a hose from the bottle to the intake manifold.

bottle pressurizes.

excess gets pushed into the intake instead of exploding into the atmosphere.

as you can see in my first post, the question was how much dry ice would be needed to create enough gas to pressurize the intake.

your wrong, the fact that it creates pressure means it will do the job,

question is how much dry ice you need to create that pressure.


people should read the entire post before jumping on the idiot bandwagon.

Re: vacuum smoke thingy question
 

just remember to set the motor to TDC before doing it so that way you dont leak any past the valves :6

Re: vacuum smoke thingy question
 

whats eh?

Dry ice vaporizes and would create condesation when it warms to room inside your mani, TB, piping ect.

A better way to check for leaks (staticly) would be to get a big conical plug thats the diameter intake pipe, drill a small hole in the center with a 1/4" bit, then shove a blow gun in it and pressurize the piping. Don't use shop air or anything (100psi would be bad) but hook up a regulator in line and run it to what ever boost level you run. Listen for leakies. Simple. ;)



P.S. You're a faggot and should have clarified what you are asking before you get all but hurt because people flamed for making a thread that looks like it was written by a 16 y/o girl with her first car. :P

Re: vacuum smoke thingy question
 

ahh, i should have clarified or you should have basic comprehension skills?

perhaps if i could draw a cartoon with bright colors then you could grasp the concept easier.

alas, my art skills are subpar at best, evidenced by the picture above.


im not hurt in the slightest, i just was responding in turn to your dumbass comment.

but hey, i guess being a self-proclaimed "toughguy" dosent make you a smart guy.

Re: vacuum smoke thingy question
 

Perhaps if you didn't make threads with stupid ------- titles you could get a straight answer, but I shouldn't expect much from someone that draws saggy cock pictures like a 3 y/o to represent his uncontrolable ideology. ::)

Non the less, you have what you wanted. A perfect way to do a leak down test on your induction piping. Just disregard the part about using a regulator and get back to us with pics. ;)

Re: vacuum smoke thingy question
 

yeha, ill try and get pics or vid if it works how i want.

^^^ I love your avatar by the way. I think she needed some discipline. 8)

only if its a 1 cylinder ::)

I have a real smoke machine and the work great :y
