I have a question about catch cans. I have breathers and I'm thinking about changing to a catch can, but everyone puts them on the driver side, but on my car, the passenger side breather is always wet and my driver side is always dry. With that logic, shouldn't i put the catch can on the passenger side? I have a 08 gt with the vortech non intercooled. Let me know what you guys think!

 

with all the PCV lines attached, the blowby comes out the drivers side.
with breathers on both sides, it gets reversed, blowby comes out the passenger side.
if you do a catch can, you need to put back the PCV lines on both sides and attach the oil separator on the driver side.
this way the blowby will be just like stock, only the separator will be plumbed in on the driver side where the blowby is so it can catch it.

i've had both the catch can and the breathers.

 

another option is to do a breather catch can and plumb both sides into it.

 

I just added one.
