I ran a plate on the back with a breather basket and "Brillo-pad" in it. Top was a metal PCV valve with a hose connecting it to manifold vacuum. Didn't have any problem on the street, but found that when I ran it on the track, from the top of third gear and into fourth, the exhaust would start trailing oil smoke. Disconnected the PCV and the smoke went away. Just too much oil in back of the lifter valley during prolonged high RPM and acceleration. Now I run a breather in each valve cover and no issues.
