You actually believe the oil not being changed for a long period of time caused this filter to puke its ADBV?
I think it's possible because if the filter was very clogged up, even though the by-pass valve was working, there could have still been enough delta-p across the filter to cause the center part of the ADBV to puke out the center hole. Could also be that the leaf spring in the filter wasn't holding all the guts together very well, which could cause the ADBV to be pushed out like shown in the photo due to delta-p.
I would believe this as the cause before I would suspect the OCI.
Again, I ask the Q?, what would you contribute to the same failure had it been a 2014 TG filter with only 3K miles on it?
This filter was probably left on a LONG time ... therefore, possible failure modes become multiple.
If the same ADBV puke out failure occurred on a filter with 3K miles on it, then it would most likely be from the guts not being held tight together.
But if the filter has 20K on it while being on a dirty motor, and it basically clogged all the way up so most flow was going through the by-pass valve, then there is continuously more delta-p across the media, which stresses everything out to a higher degree, which opens up more possibilities for a failure.
