Ron, Use a -12 on the valve covers it will slow the velocity of the air coming out of the covers and pull less oil with it. On my old engine I used a -12 line off of each valve cover that ran to the top of the dry sump tank. I then ran a -12 line from the tank to a vented catch can to vent the tank, I would get very little oil in the catch can, it would be mostly water from condensation. I used the Norris pcv breather to vent the valley separately, 1 line to the valley and 1 line to the vacuum port on the TB but I tapped that port and drilled small hole through a screw to restrict the vacuum flow to aid the catch can from dumping oil into the intake tract. I tried the filter in the valve cover on my wife's car but it makes a mess, eventually the filter gets saturated and leaks everywhere. I ultimately made tubes that cross over the engine and connect the valve covers together with a filter at the high point, I have a tube in the front and rear of the covers.
