There is a hose running from the crankcase to the intake manifold, so
that blow-by gases in the crankcase get sucked out to the manifold, and
then burned in the engine.

The valve is a vacuum valve that closes this connection when manifold
vacuum is high (e.g. at idle). This prevents excessive "sucking" on the
crankcase, that could suck out oil.

It should be trivial. Here is a picture of its location on some Civic
engines:

That's the intake manifold (with the engine at the bottom and throttle
body at the top). You just pull the PCV valve straight up and out. There
are no fasteners, just a clamp on the hose that's connected to it.

Find the hose from the PCV valve to the intake manifold. With the engine
running at idle, wrap this hose with a cloth to prevent damage and pinch
it firmly closed with pliers. You should hear a soft click, and the idle
speed should not change. If you don't hear the click, the valve is stuck
and needs to be replaced.

well, guess I don't need to add my $.02 about this.

Your pictures come in handy all the time! Your picture of the tranny
fill and drain plugs was more helpful than any of my manuals the first
time I did the job.
