I second the exhaust connected pcv system. For road coursing mustangs which stay in gear under decel at up to 8000 rpm on the new 2011+ 5.0 motors (modified intake and operating range) the best way to keep a vaccum on the heads for good oiling and not drink oil is to connect up a exhaust manifold connected pcv system and its really low maintenance since there is no emptying of the can. Also, another good option os the old turbo volvo catch cans. The turbo volvo catch cans are baffled and allow the engine oil to settle at the bottom and have a return line at the bottom which is connected to a return line to the oil pan. Typically venting to atmosphere is a no no unless you're not worried about engine longevity or are not worried about catch can maintenance.
