I need help trying to find what this particular part is called (technical name, part # etc..), it is a metal flex tube (acordian style), that it is plumbed into the top/side of the passenger side exhaust header, I am sure it has something to do with the OBDII emision system it runs from the header up to under the intake, the tube is cracked and you can hear valve tick under load, also obviously you can feel the exhaust leaking from it, it keeps tripping the check engine light because of the leak. Any help would be appreciated I want to walk into a Ford dealership and give them a name or part# so as to not have to deal with the "I cant find it sir" syndrome.
