You're probably right that ditching the lower intake hose will eliminate the huffing at idle. Nick voiced the same opinion.
Here's my question though. What effect will that have on my oil life and oil quality? Breathers on a race car that gets oil changes every week is fine, but what negative effects will that have on a street car. Those hydrocarbons aren't being pulled out of the oil so they hang around in the crankcase and eventually turn to blow by in the oil. The car will see 2k miles a year at best. Should I be changing my oil every 500 miles? 1000 miles? I just want to be sure I'm not prematurely wearing my engine internals if I can avoid it.
Here's the question in reverse, todays cars with idiot oil change indicators can run 10,000 miles between algorithm'd changes. These cars run twin mini turbos with same oil return to intake breather lines. The motors outlast the cars at 100's of thousands of miles. Oil in your car over the winter collects moisture with nonuse. Are you not going to change it seasonally?

That thing sound like a Transformer.
