Why does my 04' lb7 have a pcv valve when its already got a breather tube? It appears to be leaking oil out the crimp and I'm wondering do I really need it, or can I just remove it and plug the hole. Also, it is threaded into the "oil separator". What the hell is an oil separator?

Well I had the PCV mess up a few years ago & was blowing oil out the breather. The shop I brought it to said the valve was plugged. I was fine after.
