Edit: Make sure you put the right oil in it. The 6.7 powerstroke has very tight bearing tolerances which is why I believe it calls for 5w40 but don't quote me on that. A very well known engine builder has gone on the record by saying that every bad 6.7 that came to his shop has had a spun bearings on them. If the weight of the oil is higher than it should be then the right amount of oil isnt getting between the crank/cam/whatever and the bearing. This is really an issue in colder climates.
