They went to what they call "fixed venturi" PCV which if you thing about the way the PCV system is designed to work the PCV valve can NOT be fixed. It needs to be variable and two way to work properly. If they put extra baffles in there I guess that would turn the area under Bank 1 rocker cover into a big catch can of sorts. I went to Harbor Freight and got a OIL/WATER separator for an air compressor for $8 and two hose barbs at $2 each. An other $2 for 3 feet of 3/8" hose and you've got a catch can for under $20. After seeing what you find in your catch can you'll wish you had one on there from day one. In areas of high humidity you'll also find water in your catch can(or water and oil mixed-MILKY) which is the result of condensation in your oil pan after the engine goes through cold soak.
