Good PCV = $25.

Moroso single 3/8 NPT entry vented catch can = $40 with a Swank Force One hookup.

Your call.

 

Wouldn't I want double entry? Or how would I plumb a single entry? Just leave my filter on one side?

 

In an ideal world, sure. You could "T" the hoses together before they go into the can in this case. Makes for easier packaging anyways. Will still probably flow better than what you've got going on anyways.

I could enter you for a second time if that's what you're REALLY asking.
