Hi All!
On the subject of finding vacuum leaks, traditionally we use hand vac pumps and that is good for many leaks, but what about the intake manifold and surronding areas as a whole? Spraying carb clean on a running engine might find gkst leaks, but how about using smoke, injected into the intake via a vac port, to diagnose the system as a whole?
I came across some videos on youtube last night using smoke to diagnose a variety of vacuum, exhaust, HVAC and related engine issues. A unit called The Smoke Wizard looked very impressive, but not cheap. Most smoke machines are around $800-$1000. To make one yourself is possible, but to use on a regular basis, safely, is the question. Look yourself on YouTube under The Smoke Wizard, and RealFixesRealFast - a very knowledgeable mechanic. I learned much just from a few videos and applied them today at the shop I work at.
Anyways, I was thinking in a vacuum and wanted to throw this out to see what "the family" might be thinking. Think in a vacuum - the groove needs it to be at its best!
