I have pulled apart a LOT (20+) blown 2.5's, a couple had questionable bearings, but none of them had failed completely.

Brad I have a 2.5 now that has jumped timing but I have not pulled the bearings out to see if that was the cause. I retimed the engine but one of the cylinders has low compression. comming out the bottom end that's why I did not bother with the IMS. Now, however, I will have to pull the bearing to see it that was the cause. Will let you guys now end of next week
