Message inside the engine that atmospheric outside. In the plenum air is below atmospheric. If smoke injected in a vacuum hose it has no chance of leaving thru a supposed vacuum location to the atmosphere. Seems the correct way is to pressurize the plenum with smoke so air/smoke would escape at supposed leak areas.
