It helps keep oil down in the oil pan. The 4AG largeport head only drains on the exhaust side - fine for transverse layout, but in a longitudinal layout a long left hand sweeper can emply the oil pan of oil and pack it into the head. Additionally it helps with a catch can as often times the catch can fills for the same reason.

Thanks! So it's meant to have the same function as the breather pipe.
