Yes.

Draw crankcase fumes out & allow plenty of fresh air in. Don't want to draw a vacuum on the crankcase with a wet sump, the oil pump would stop pumping oil. So the Breather on the opposite valve cover must always be big enough to flow plenty of air, more than the pcv or aspirator can draw out.
