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.

It's interesting as the F20C had a similar problem despite it's Longitudinal layout. It gets stuck up under the head baffle plate and makes a smoke screen.



People have to drill the head baffle to allow it to drain.


I've had friends with F20C swapped 86s black flagged because of it.
