There are two vents on your valve cover. One is to the left side (this is looking at the engine) and the other one is on top. The one to the left is good to have on a catch can because if you don't have it connected it will sometimes leak oil in your engine bay. This vent is usually hooked up to the intake pipe that is on the turbo. Make sure that it is plugged!

the other vent on the top of the valve cover is a valve and you would need to modify that to hook it up to the catch can. I would just leave it.


Make sure to empty your catch can ever once in a while!
