    I removed my PVC lines and I use a breather like that. One of my friends does the same thing.

    When you put a breather on the valve cover you are venting the engine to atmosphere. Defeats the purpose of the pcv closed system. There are lots of good arguments against this. Search & read.

    I've got a question on this subject. I am replacing the pcv valve and some of the hose because it has rotted through. Should I go with a catch can or breather cap. Reason I ask is because right now it is spraying oil from somewhere under the hood in that area and my dipstick is rusting like crazy. I know some of you say that a breather cap eliminates the need for a pcv valve. But will it be OK to have both?

    I see most of these catch cans you guys have are about $100.00 from the WS6 store and Thunder Racing. Are there any that are less or is it worth the extra money for these? Because I really don't care what it looks like.
    Let me get this straight, I am running a stock motor, with a new pcv valve. If I get a catch can, should I need an oil breather cap too?

    you don't need a breather but its a little better setup with one. At WOT there is more blowby and more crankcase pressure. Crankcase pressure creates resistance for the pistons to move up and down. on the Factory setup, that pressure get vented through the PCV valve/line into the intake. It also get vented into the TB through the other PCV hose. With that vented pressure goes oil mist which gums up your TB, Intake, and valves. The Catch can catches that mist and a breather vents to the atmosphere instead of back into your TB
