I'm curious what I should do exactly as I don't want to use catch cans or vent to atmosphere.

I have a Harrop kit, and all the PCV and vacuum lines are routed pre-blower so those ports never see boost, so a check valve isn’t necessary, nor is it necessary to upgrade to the WRX FA20 PCV valve, but I did anyways. I don’t know what Edelbrock does.
I had a plastic connector break which made for a poor idle and poor performance overall, but much more noticeable at low speeds. I replaced it with a brass connector, and everything was fixed. I also had my direct injector seals that needed replacing, so I was working on that when I found the big leak.
