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.

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...

Re: vacuum smoke thingy question
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.
