So, since much of that is from the PCV, an oil catch can helps as a preventative mod, right?
I didn't think my OCC was doing anything, since there was only just a touch of oil on the end of the "dipstick" the can has (it's a BSH). Was mucking around on something else and decided to pull it off to empty it and see.
It had about an ounce of oil in it after the 1000 miles. More than I thought was there. FWIW, my car has not required oil between changes (so far).
