Well I received a call that our engine was back together and has a good test drive. Another test drive is going to be done to insure there are no loose ends. We expect to be able to pickup the coach on Monday 7/2. Waiting for a call back about the next test drive.
Ok what went wrong? One valve seat dropped and that took out the after treatment, DPF - Diesel Particulate Filter, both turbos, cracked atleast 1 cylinder sleeve and other stuff. I was told that the EGR cooler was replaced, all cylinder sleeves and a lot of other items with updated parts. Apparently there were several parts in the initial build that they found did not uphold well, I don't have the specifics, and those parts were repllaced with new improved parts.
That's all I know now.
