1G PCV Setup #3 – Maximum Pressure Relief

[NeMiZiS]

I'm curious as to what 4 port sealed catch cans y'all are running for this set up?
I can't really seem to find one that is 4 port and sealed.
I'm referring to the famous catch can wiki.

A sealed can will not have the most pressure relief.

A sealed can will not have the most pressure relief.

how so? its a constant so will always be drawing vs allowing it to naturally push its way out! enclosed systems do much better at the job vs an open plus you dont get fumes everywhere and oil deposits messing up your engine bay AND if still on a maf system then you dont ruin the air counted by it.

run a proper enclosed system and you will solve your issues. how far to go is upto you! i have mine even taking pressure buildup out of the crank area and it can also self vent into the can at any point with a 1 way valve.

using a vac vs self pressure means you get all the deposits out all the time where as open can relies on the internal pressures to push it out meaning it stays in the system it self pressure builds.

open vs closed is a huge debate by many but safer for an enclosed. do it right and wont have any issues

I was just trying to follow the guide.
It does seem hard to find a nice sealed 4 port can though.The Calan catch can isn't a thing anymore and all the nice 4 ports units are vented.i don't claim to know which is better sealed vs vented.

I also run a closed system (stock pcv with a check valve and two breather tubes running straight from the VC to the turbo intake)

I like the idea of pulling vac out too. That being said, depending on how bad your blow-by is some people STILL needed a catch can and if you do, then you obviously need a vented one because the vacuum isn’t doing a good enough job if you’re still pushing out oil.

What catch can are you running?
I don't really have much blow by and just wanted to build a catch can set up and do it right one time.
I'm really just looking for ideas and what is a quality can to buy.

vibrant has a decent looking one in both vented and closed loop and it's good size.

Radium Engineering has a few options as well that can be VTA or Recirc. I was planning on switching to one of theirs from my current set up eventually.
