It's more about how the end caps seal around the ends of the center core at the end caps - sealing surfaces for the ADBV and bypass valve assembly. End cap flexing and distortion during use could cause dirty oil to get past the filter media.

It just makes sense that if the fiber end cap is more thick/ridged, that flexing and distortion would not occur and give the filter more stability and reliability. That's my main point with end caps. Of course, with metal end caps you inherently get all of that.


Here's a perfect example of that from the current Honda -A02 filter thread:

There's no way the ADBV valve was sealing against that mess and preventing bypass.

And heres my reply to you in that thread.

Yes. Take a look at your second to last photo in the second set. There's no way the ADBV was sealing against that rounded, wavy cardboard surface. That filter had been continuously bypassing unfiltered oil for some time.

...


I think the rounded profile may be barrel distortion from the camera, it doesn't look so bad in the flesh. This is actually the dome end and there is some distortion from the bypass valve/leaf spring. One can clearly see how the spring was oriented when inspecting it in person. (the leaves would be in the foreground and background in that photo.) The bypass/spring fits into the media with some friction fit.

Insolubles on this run were 0.4% versus 0.3, 0.2 on prior runs.


I'm not sure I agree with your assessment.
 
I think that one had about 7500 miles on it IIRC. I'm not sure I agree with your assessment either, I can see the seat marks but not well, but I do think the design fares better at 5k max. UPDATE: The OP stated the picture above is of the dome end, which makes more sense.

Here's one of my orange cans at 5k, straight and rigid and this was with coolant contamination. You can see where the ADBV had been firmly pressed against the end cap during use.

No, that impression is from the spring/bypass valve assembly. The ADBV is on the opposite end. If you're going to defend FRAM filters, at least learn which end is which.

In the A02 thread the first picture of the second set shows the dome end with the impression of the metal spring/bypass assembly. The seal appears to be complete, even with the off-center tube. The image I linked in this thread is the ABDV end. Pay particular attention to the area at 10:00 and between 2:00 and 3:00. You'll be hard pressed to convince me that the ABDV sitting against this area was making a complete seal.

From the looks of the light and shadows on the end cap, it certainly looks distorted to me.
 
Ed was correct that the earlier picture was the ADBV end and I was mistaken about what. My apologies.

Here is a better picture.

WRONG.

It's my filter, I cut it open. That was/is the ADBV end. The ADBV was so firmly seated against the fiber endcap a little of it stuck on the ADBV, which can also be seen in the pictures on the thread I posted on it. The leaf spring (no bypass for GM but the spring is the same) is metal and fits into the metal center tube, there were no marks on that end.

There are more pictures on the thread I posted on it, including one with the ADBV in place before I ripped it off the endcap.

To make it easier, here's the pic and I marked it. The ADBV was so firmly planted against the media a little of the fiber lifted up attached to the ADBV when I pulled it off.

For the record my favorite value filter is Motorcraft, but I dislike the irrational hysteria that surrounds the orange can and finding Motorcrafts for Chevy applications is difficult.
