Thank You for the phone#. Regarding the engine rebuild. We had a small oil leak. It was determined it was the head gasket. They removed the head and determined that some of the sleeves were out of tolerance causing the gasket to fail. Cummins recommended that we have the engine rebuilt. We had a good extended service policy so I said go ahead. Nineteen days later, we had completely rebuilt engine including a new head and a new turbo. $30,000 cost us $2000.
