ok just need to know what is the best way to check a vacuum system for leaks
is there a pump or something you can make or use compressed air ????? someones gotta know

the only way i was told my one of my friends is to take carb cleaner and spray hoses until the car chokes but i dont want to do that

i wanna be able to put air through the system and hear for the leaks anything like that so if anyone knows please let me know ASAP thanks

 

ttt

 

Many of the systems that are attached to vacuum hoses are supposed to be blocked off when the car's off. You can use a MityVac to check each one to see if it leaks. That's kinda tedious...

Take a propane torch, NOT lit. Spray propane around the manifold & anyplace that you suspect. Idle will increase when it sucks propane into the engine. There's a fire hazard, so use some care & common sense.

 

uhh anything a little less hazardous

 

anyone got any other suggestions.

 

HELP

You asked for the best way, that's it.

 

i normally just use a can of carb like previously mentioned

 

i take the easy approach, and if it seems like i have a vac leak, i replace all my lines....vac line is chap and easy to replace. Also if 1 line is going then the rest might be going soon too

 

i have tried all the procedures everyone else is saying and they are right. you do have to be careful though cuz you can start a fire. Another method you can do is use a stethscope and listen for leaks. no potential fire hazard doing it this way.

 

There isn't much vaccum on a modern honda motor anyway... what exactly are you looking for?

if you dont have much vacuum you got problems
how much vacuum should a "modern" honda motor have??

 

It's already been said

propane enrichment testing or go get a can of air intake or brake cleaner.

Air intake is safe for o2s and cats.
