Recently, I changed the PCV valve for the first time (at 110k miles 2015 ody) as a preventive maintenance.
It's easy and VERY inexpensive (~$25 for genuine Honda parts) procedure to change yourself. Took me about 5~10 minutes.
I don't recommend using other third party brand as they may not have the 'rattle' you need. I bought one from eBay for $10, a 3rd party one; although it fitted just fine, it did NOT have ANY rattle as if it is stuck open/closed! I returned it and got genuine one.
I'm not 100% sure if this made my car a MPG boost, but ever since I changed the PCV valve, my car range for full tank of gas went from 380 miles to 450 miles! And stayed that way for a month. I normally put gas once every 3 days (driving about 100 miles a day), but now I go on to the 4th day.
I did not do any other 'upgrade' when I changed the PCV valve, not even an oil change. Just changed the PCV valve to genuine part.
The dirty one was some what not 'rattle-y' but still little bit of rattle left. But the new one of course has whole bunch of rattling sound when I shook it.

When you remove the PCV valve, it may SHOOT OUT of the housing.
So turn your ratchet slowly and grab on to the PCV valve as you remove it.

Some of the online (YouTube) video shows the metal bracket inserted BACKWARD!
This is HOW you should insert the metal bracket.

Obviously the old one is dirtier but that's not the important thing.
Important thing is when you shake them, it MUST rattle! (sounds like a spring inside rattling)
So, the verdict?
CHANGE YOUR PCV valve regularly! I'm planning to do it once every 30k or so. So easy, quick and very inexpensive there is no reason not to do it more often than not.
I thought this would be one of those unnoticeable preventive maintenance, but with such a huge MPG boost I got, I thought I'd share with odyclub community and highly recommend everyone to do it if you haven't done it yet.
