PCV Valve:
It's located on back side of block, down below the intake system. Not much fun to get to. Has a hose that goes up to the intake system; may as well replace that hose too if you or someone gets involved in that system.

Oil changing - staying clean:
Hondas like to unload oil onto your arm, shoulder and on the exhaust pipe when you pull off the oil filter. I seem to have found the fix for this, about two years after buying mine:

Use Honda brand oil filter. They a smaller diameter can, so it doesn't hold that extra reserve of oil that doesn't drip out via the threaded spin-on tube. Aftermarket filters will have a larger diam can and same size threads + gasket, and will fit but will drip more.

Jack up rear end of car as high as you safely can. That tips the filter forward to empty it more thoroughly. Preferably engine is hot so oil will flow well. There's a tow loop at center rear; put jack under that. 2x8 board under the jack if you need more height than the jack can do. Leave it up for maybe 45 minutes or more. Overnight is OK too. Then drop the rear, and lift the front as needed to change the oil. Put a rag under the oil filter's forward end to catch what does come out, but with that preparation you won't lose much (usually).

Good luck with it!
