I installed a recirculated catch can setup due to perished pipes etc and performance definitely improved for it.
I was recently looking into a vta setup as can emptying is quite regular and don't like the idea of it freezing in winter, then I read this old thread which explains several reasons why you need a pcv valve, hockey puck and a recirculated setup.
It seems to make sense to me.
So I'm going to re pipe my setup in the near future.
Have a read, see what you think.
Have been searching for a couple weeks but haven't really found anything this particular or even similar so I thought I'd throw it up here. I have a 1.8t and deleted the Pcv valve and installed a vented catch can. I'm not sure if it's the colder weather but it looks like there's liquid...
