Good find NYC Ernest. Thanks. It's close but I think one needs to put out about 3lbs pressure to push the smoke thruout the system. That raises the comlexity some. I can't understand why one of our more intellegent designers of special tools hasn't take up the challenge to make such a useful item for the home mechanic. Would work on Hondas and Fords too.

 

Haloween-type fog machines use glycol or mineral oil.

 

Make some fireplace bellows, pull the air filter, plug the other side, and enjoy.

 

Just spray fittings with carb cleaner and listen for the engine to idle rough for a second. Ussualy works well for finding vacuum leaks. I've also seen a mechanic use propane, though I somehow think that would be dangerous, should it hit hot headers.

Fog juice is very sticky and would really crap out the internals of an engine. Indeustrial fog machines use dry ice still. The fog stays low, about knee height and rolls off the stage. Smaller chemmical fog machines create a smoke that is lighter and will fill the room it's in.

 

video production houses or rental stores carry fog machines. They do burn a liquid that leaves a coating on everything within a few feet of it. I use them occasionally for photos.
