We go to great lengths to build a high power engine to breathe like a champion then ignore it's ventilation and evacuation needs or just use a band aid instead orrrr a catch can !
Catch can should not catch any oil the oil belongs in the oil pan and they should not vent to free air cause that stinks the car they should not be connected to the center or the top dirty air should go in lower side and the bottom so air will clean out on it's way up and out the top to be inhaled into the motor 100% clean and the bottom hose should go to the crank case to return oil there where it belongs while the crank case itself is ventilated.
Never need service never need cleaning or emptying can be installed out of the way and is a complete high performance engine evac system clean filtrated air is absorbed by the motor from cold air intake.
I do not understand what you mean ??? Is this a part you are referring to ??? I agree with what you say , why is this high performance engine not properly vented ?? And can this be why so many vet owners complain about a rough idle ? I know I am very disappointed at the way my 2010 LS3 idle's . It screams after a lag / hesitation? It stumbles off the line and then goes like a rocket . To me this is unacceptable and runs like **** .
I just added a mighty mouse cc. I am running AN lines from welded fittings on my valve covers to an AN y-fitting over to the catch can. I also added the drain line on the can to make draining easier.
You can see the Black AN lines to the right of the VSC.
