The bank with 6.5 degrees is the unit that has emitted the pieces of debris.. You have about 2.25 degrees more before it sets a CEL for being out of range. The 6.5* is already costing gas mileage, adding to the rough running index and adding fuel trim.
The servo units are not serviceable and thats why no one else has found the source of the debris, because they have not cut the units open. As a researcher, doing the things that no one else does and finding the things that no one else has found is my job.
If a unit fails, just replace it.
BTW- a failed servo for the VVT arrangement is mode of failure #5 of the 27 documented modes of failure for the M96 engine.
