Hi, I've a theoretical question that ties into something I just noticed.
Is the connector pictured under number 1 in the link below a simple connector or a valve?

From what I've read the PCV system should export blowby through there into the intake manifold. I'm just curious what the function of each line is and and if it's true that the PCV air intake is attached to the air cleaner box.
If it'd be just a connector then why two separate lines (one thinner and one thicker)? Also if the connector is leaking around the base is that bad?
