Opinions on Valve cover Oil breather. Come on in

So after I had the porous block/main seal repair work. My dealership questioned the crankcase pressure. I completely discounted that comment by telling them my PCV tubing, intake plenum were completely dry. I also advised them that I had a catch can installed for approximately 2000 miles and collected not a drop of oil. If the leak were associated with increased crank case pressure, I would have oil in the pcv tubes etc. We agreed on that.

I started to research the pros and cons of a valve cover breather and thought I would try one. I know it will not improve performance but if it will help the existing PCV system reduce pressure, it may be a good thing. I found a Metco breather and installed it along with the existing PCV system. I took a spirited after the install drive and there was no cabin odor, or oil mist collecting on the valve covers and no leak.

My question is: WILL THIS BENEFIT OR HARM MY BUILD?

Here is the product:

Here is the install photo. I opted to install it in the plastic fill tube although it can also be installed directly into the valve cover.
