I'm running 1/2" lines on each valve cover and the oil filler neck. There's also a 1" vent/filter on the top of the oil tank as well.
I know the dry sump pump isn't strong enough to pull a vacuum but it seems like there is excessive crank case pressure to me. I thought it might be that the rings haven't seated yet as there is only 2 hours of dyno time on this motor, but it should be dry from the get go.
