Smoke test results, when is a leak a leak ?

[SuperSwede]

Just try to figure it out, when is a vacuum leak a leak to consider or not.

 

I have a good smoke machine with supply from a air compressor set to 15 inch hg.
The first test didn't show any leaks except a tiny thing from the butterfly axle but it was really small.
The second test at  20 inch hg showed some more tiny leaks after maybe 5 minutes under pressure and a LOT of smoke in the system.
One at the combined vacuum harness connector, one at the EGR valve axle, one at the top of the EGR transducer.

 

Thoughts about this?

Your smoke machine uses positive pressure (above BARO). Most vacuum hoses are under negative pressure (below BARO) and don't require hose clamps. Five (5) minutes with 20"hg (positive pressure) without no large or small (not super small) leaks, tell me, system is good.
