Nice work and am enjoying your detailed photos. One photo on the passenger side valve cover shows and you mentioned adding a PCV valve.
Just a comment--In past years, I added a coaleasing oil filter on the passenger side. Not ever in 3+ years of driving did I see a drop of oil in that filter on the passenger side. The passenger side is to allow the lower crankcase to breath in and out. Which means that in boost, excess crankcase pressure must be exhaled out to prevent pressure from blowing the crank seals. So, not sure you need a PCV valve in the passenger side, In the factory setup, the passenger side was vented into the air box which would allow crankcase air to move in and out. In an N/A setup, the passenger side needs to allow for some air to be sucked in, in the amount of air being pulled in through the PCV system on the driver's side and routed into the upper intake manifold.
In my particular turbo setup, my passenger side is pulling crankcase air from both sides during non-boost motor running which creates a vacuum (from 0 to -5) in the lower crankcase, a good thing which helps the crank seals seal. During boost, the driver's side PCV has a check valve which closes that side of the system and the passenger side continues to pull vacuum from the crankcase to prevent ring blowby from pressurizing the crankcase. Thus far, in 3 years of running, no crankcase seals issues and no oil dripping from the rear seal.
