Thread: pcv valve?

  1. #1

    Default pcv valve?

    hey guys, could the pcv valve make my suburban run rough if it has a bad hose or is broken?

    Yes, it will create a vacuum leak.

    Default

    i tried to fix it but that wasnt it.
    could it be the paper gasket on the air cleaner extention?
