Need moral support: Cummins engine problem

Update.  Just took my coach to Cummins for oil change.  They discovered carbon deposits on exhaust gas sensor tube (Rapid City changed the sensor twice) and a leaking valve cover where they cracked a fitting.  Plan on mailing them pictures, but I doubt they will feel much of a need to respond.

Delta P tubes? Very, very common place for carbon to build up and shut you down.
