On LS engines the stock LS9 style valve covers have baffles and I think the LTs do also. We drill out the old 3/8 inch vent nipples and add a -8 AN nipple. This 900 - 1000 HP engine need a way to breath. If you don't get the vent large enough we have blow out rear main seals (Not good)(Big Fire). Also don't delete the factory PVC vent system. Air needs to move through the engine to get moister out.
A lot of air oil separators need to be drain manually, I don't like that. I like the Mann and Hummel's or similar that have previsions to drain back to he oil tank or pan. You don't need to remember to drain them.
Oil and or a lot of oil vapors that get into your intake will lead to preignition issue if it gets out of control. It is best to keep it under control.
