Funny when I show a defective Fram TG, worse defect than a torn pleat IMO, there is no condemnation of them. Every day thousands of PF64's are being installed, very common size. Maybe Cadillac will take note and Champ will tighten their QC on the pleating.
Link to your defective TG please.
I think it's the type of failure. A media tear is more likely to happen than other defects. However, I am the last one to give any brand a pass for junk.
About 6K miles. I posted this as a new topic but removed it, "not worth it." I was right given the hypocrisy. One torn PF64 equals one TG like this in my book. The second glue shard was on top of the baseplate. Since my filter points up and some oil gushes out I only can assume it was in the oil gallery above it. This shard was inside the center tube. I think the open space where the end cap doesn't cover the center tube is the problem. I believe when the adbv was compressed on the end cap the sharp center tube cut through the glue in the empty space with no end cap. So no more of this kind of filter for me. Just like everyone else does when they find something. Since I can't see if the end felts are centered well enough, I buy others. I predict the same response as before, disbelief and dismissal. Pictures or not, doesn't matter.
I can see how the glue would have come loose... in fact you can see where there is no glue on the top of the pleats where that space is. This is why a design where the ADBV seals to a protruding center tube "lip" would mitigate against that type of failure, like the Suzuki filter I cut open:

I don't blame you for not wanting to use a filter with that design. And your experience is added to my library of design considerations I want in a filter.
