Yep, that photo describes exactly what I am trying to do, but why do the
grommets require such a difficult removal? My shop manual says the PCV
orifice tubes should be inspected every 30K miles.....so I am expected to
buy new ones every 30K because they cant be removed without breakage? Gotta
be a better way, right? :)

They are rubber, and if you really have to break them to get them out,
by definition, they need replacing. The material hardens with heat
and age. The new ones can be installed without breaking them. The
idea is that the harder rubber compound does a better job of holding
the air intake [front hose] and CCV fixed orifice [rear hose] in
place.

You could probably find an online rubber grommet repository and buy
ones that don't harden with age. Or you could just pry out the
current ones and replace them with new ones. Like most engine
rubber components, they need periodic replacement or you get lots
of easily avoidable blowby...
