Just sayin....
Haha zombie thread.
The engine that that filter was on was a direct injection with overhead cams driven by chains. They are hard on oil. The engine is not dirty though. The wix filters that I had run during the same time looked way better than that ecore. The ecore got ran longer than I normally run for oil changes plus it was not technically the correct size. The dealer installed the filter that was speced for the older models. It defiantly wasn't run outside of gms recommended oci but just barley held up to the job. To close for comfort. If it had turned out like several of the ecore that have been posted here lately I wouldn't have a problem running them.
The vehicle calls for a PF63 or PF63E which is a larger filter than PF48E.
I don't see this as a filter failure when the incorrect filter was used.
The shop doing this should not have used the smaller filter. Unless they also stated a short OCI be used.
From the photo, it looks like several pleats were in bypass. This means unfiltered oil was circulating through the engine. If this were my Traverse, I would do several short OCI until the oil cleans up. Then resume normal OCI/FCI with correct parts.
The same motor used to use the pf48. None of the pleats were in bypass or torn. I have use plenty of Napa pf48 equivalent filters on this same vehicle and none of them looked like this so yes this is a filter almost failure.
Since you previously had good results with PF48 then I suspect something has changed. Exactly what has changed appears unknown. 1) a bad/poor filter 2) an engine that is now producing more soot than before 3) some other unidentified cause.
The current 2013 Traverse owners manual calls for the larger PF63 / PF63E filter.
I am not questioning your maintenance plan.
Thanks for your post.
