What is the purpose of this dohicky?

Hi
06 aveo
what is the do-hickey that is between the PCV valve and intake.
It is bisected by, what looks to be a water return hose.

Could it leak water into the intake?

thanks

thats the route the pcv system follows, for crankcase pressurized air to go back into the intake..

i guess water could leak into it if you fill the engine to the tippy top with water. the system should be sealed between the valve cover and intake.

-picture ?

I'm pretty sure its just a fancy fitting that makes for a slightly cleaner looking engine bay. A bit nicer than two hoses passing each other, but a waste of money IMO. They don't allow one system to leak into the other.

OK
Thanks
