Blocked PCV system and valve cover breather

[99BlackW68]

I used to have a Supercharger on my car but I've sold it and am sticking with N/A. I blocked my PCV system and the TB with a threaded plug and have a valve cover breather. I'm wondering now if I should remove the plug to allow the PCV system work as it normally should, and remove the valve cover breather and replace it with the stock oil fill cap. For the most part my car is stock now, so do you think I should get the PCV system running as it was? Or just let the valve cover breather do it.

I bought my car and it previously had a turbo. I couldnt figure out that nasty whistle until I found out about the internal pcv system. Ive been running a breather for about 5k now with no problems.

Mine had a high pitched whistle but the engine had to run for about 20 min forit to start. The minute I took off the cap to let it breathe the whistle stopped its the only reason I found out what it was.
