Breather reroute question.

[juGGernaut]

Was installing my new catch can and noticed while the bike is running, air is being pushed out of the breather reroute filter, is this normal?

 

[GOduc]

Yes. Normal. Would take me a while to give he long scientific version but yes it is normal

 

[BuellyBagger]

/\[up]yep its all good

Normal. It's basically a vent for excess pressure that builds up in the crankcase.

Ok cool, so what's the point if putting a filter on one end of the breather if its just pushing air out?

Side note, I am looking at doing a DIY for hearing protection head phones, I think I have the modders itch.... Been busy on my bike

Pressure release which will allow flow of excess fluids you'll find in the catch can.

^exactly. It doesn't vent just pure air, there's oil vapor and "gunk" in it as well.
