    What valve cover vent lines are you talking about?

    Those lines under the intake are most likely the coolant lines. You can bypass them with some fuel line.

    you will gain very little by removing this stuff. It's more of a cosmetic mod vs a performance mod. You can trim the egr tube where it pokes into the intake to get it out of the incoming air flow. Also, if you don't adjust the timing tables you could start seeing some tip in knock retard when you remove the egr. I did on mine.
    If you decide to pull it off I would leave the pcv system in tact ( lines that go into the valve covers).
    Other than that just pull off the egr and air and plug the empty holes and drop the air pump out from under the car. Tape off the connectors so moisture doesn't get in there and corrode them and pull the air pump relay out of the fuse box.

    yeah after you remove all that stuff you need a computer tune so that your SES light doesn't come on.
