I've wondered about this as well . . . if the catch can or "filter on hose" vents into the engine bay, wouldn't the engine fan draw the fumes in and then blow them through the cabin heating sysyem (as well as all over the engine itself)? Some past posters have said this is a problem and others have said it is not . . . go figure.
