After a year if daily driving and 1 track day, this is what I emptied out in my catch can. http://img.tapatalk.com/d/12/10/02/heda5yqy.jpg

So for those of you that says NA's don't need a catch can. Here is my take.

what can? Is it hollow?

On a naturally aspirated car - probably good for a dedicated track car - but a total waste of time and money for a daily driven car or occasional track bounce.
Better to replace your PCV with a new item - this is often overlooked in the maintenance schedule and many many hondas drive around with broken or weak PCVs which do not close under full throttle - this pulls through more oil vapour than usual.

You should see what a turboed car leaves in a catch can in a short time !

I've checked the original pcv and it rattles fine. The catch can actually has a pcv as well so I'm running 2 in series. There could be a chance that both mighty be faulty but highly unlikely.

sorry - i meant to imply that there IS blowby but this blowby is cut off under full acceleration / WOT. So , even if your PCV(s) are in brand new condition there will naturally be a tiny bit of oil sucked into the inlet manifold.

As you can show us - not anything to be worried about.

u mad?
