Cobrabill: The misting on my car was under the breather caps. The mist from your engine is going out the road-draft tubes. I suspect you're getting some
oil under your car if the vent tubes are doing their job, i.e., venting the crankcase and puke tank.
Back to PCV valves, they have no downside, so why not work one into your engine's crankcase-venting system? It ensures moisture and other damaging vapors boiled off
oil in the crankshaft is removed, extending the life of your engine. And this is done without any drain on your engine's power. Maybe because it's considered a anti-pollutiong device?
