Hi how mutch in ventilation /open vent in a drysumped engine, I my self use two open inlet from valve cover and one open in crank vent , Dicussens has been strong on the 50 years jubilee at Mantorp Park , Sweeden , My system is still not good , Perhaps foming or anything, The tank is just like a Peterson , 7 liters OVE.

use the engine crankcase breather and the oil tank breather and connect a catchtank to both breathers
