I fixed one a couple years ago with same fault code & symptoms. Timing chain guides on the Right bank were broken in many pieces. The tight side of the chain typically has a slight arc inward because of the guides shape. Once the all nylon guide self destructed the chain became straight causing the cam to be retarded from base timing. With the inboard guide gone all of the slack needed to be taken up on the tensioner side guide. This particular engine also had failed oil filter screens in both of the phaser oil control valves. The screens had fatigued allowing wire fragments to enter the cam phasers.
