Checked my PCV valve. Took about 5 minutes. Seems fine.
(Poop, I need to investigate more)
19mm wrench fits fine. Fit, turn, spin, repeat. Leave the hose on. Use needle nose pliers to pull it high enough so that it can be grabbed and removed from the hose with a channel-lock or something.

update:
I dunno what to call this, but I broke the **** out of it trying to get the PCV hose off.
These hoses are hard as rocks and really do not like to move.
I'm pretty damn sure I'm leaking oil from here.

Yep, short fat hose was cracking up the side on the dark half.
