Steam through vacuum leaks?
 
Wondering...can I use water-based steam cleaner to find air leaks? I have one with dry steam option...lots of steam. Or it's a bad idea...for sc..engine..close pipe at throttle body maybe? Searched around net couldn't find anything, what u guys think??

I've read and believe that you co...uld just use a water bottle/spritzer and pick up vac leaks, you'd certainly notice a dip when it gets to the engine. Old school method of decarbonizing engine is what I hear.

I wouldn't put steam into it like that. Can't say why, but it sounds like a bad idea to me...intake doesn't get that hot usually...nor would many sensors and the like...you could use a cigar and just blow it in manually...but water mist should be noticeable. Guys also use carb cleaner and spray it around too...listening for a change in rpms.

Yeah...just not everywhere u can reach spraying. Cigar method may not give enough pressure to open up leak. Interesting that nobody tried steam machine...or saying anything about it:hmm:

Hate to cross post but there are quite a few cheap and easy ideas here for testing for vacuum leaks.
