DIY Stop using carb clean for vaccum leaks!! Here is a alternative

Build this smoke machine for under $30 and be able to find vaccum leaks the correct way!! Carb clean will not show most vaccum leaks, this will help you find those very small vaccum leaks!! This inert smoke will fill the intake and leak out the smallest leaks, indicating where you have an issue. This is the only way to properly find a vaccum leak!! Our profesional machines work better. However most of you DIY's do not have the money to drop on the tools that we use. But this will get you close!!

1. Do not argue with an idiot. He will drag you down to his level and beat you with experience.
2. Light travels faster than sound. This is why some people appear bright until you hear them speak.
