A film should not be a problem. Blowby happens when the crankcase is overfilled, and it's really noticeable, not a film.
When your engine cools after a run, it will draw in outside air as it cools. If this air has moisture in it, (usually does, more on rainy days) it will condense into water in your oil/crankcase. When you run your motor again, it heats up, the water becomes vapor, and it comes out the vent tube. For a little oil to be carried with the water is normal. This is the cause of the film.

On Honda Valkyrie, the crankcase vents to the air box. Vaporized oil and moisture collects there and drains off in a "drool tube". I'm not familiar Harley, but a lot of this gimmickry is mandated by Big Brother.

sounds like the result of "blowby" check the pcv valve make sure its in the correct orifice, and check the lines for rips or tears, also does this vehicle have a smog pump, there may also be a problem with the one way or "pulse valves". good luck
