He told reporters that he had no warning that there was trouble because his engine ran well all night. He's not really sure 'what' happened but said the "motor let go."

Usually when oil runs out the bottom, it's not so good."
Jamie started the race at the Charlotte Motor Speedway in 35th position. This is his second 'DNF' this season; the previous was in Phoenix, AZ due to a crash.
