Hi , i have a ford F450 2008 6.4 diesel. I was having trouble with my truck bucking while driving . The Ford dealer found a round of metal the size of a pea that is tapered on both ends , stuck in a hose that screws on the exhaust back pressure tube . The dealer says its not a Ford product. No warranty ... I bought the ford new and they are the only place it has been for service . Help ... do you know where this piece of metal came from ... looks like it is designed to move back and forth to stop air to the turbos.
Thanks Darrell
