I'm running a universal 3 port mishimoto catch can (I bought their mounting bracket separately through their customer service.) I also have a straight through pcv valve. PCV and CCV go into my can and the middle port is VTA. I can see oil coming out of the middle port. So I assume it's working as it should. Sorry the pictures aren't catch can focused, but you can see how it's mounted towards the top center of the car. The first picture shows it on the right. The left port on the intake manifold is capped off, as well as the nipple on my intake pipe right before the air filter (not pictured).
