Filters with a metal-on-metal seal between the leaf spring and metal end cap use to be stamped smooth and show no gaps with with a light test. For me, any leakage gap in that area is unexceptionable. I see no reason to accept bad quality on filters that use to not have these issues.

Would you throw away and not use such filter knowing about it, or still use it. and being fully honest …
I used and I knew about, no issue for me with the some tiny amount oil passing through
The filter still is looking good after the use
As long as you’re in okay paying for and using a filter that most likely is not as efficient as it claims. IMO if you’re paying for a premium filter you should be getting premium construction and efficiency. Also keep in mind the longer the oci the more important efficiency becomes.
See, you have a stash of premium filters you bought while ago and the flash light test is not a thing yet, what’d you do, particularly you? It is easy to say looking at others.
I bought a bunch of carquest premiums now, and who knows in the future if someone finds another flow in it
So I did research and not big of a deal to use it
So I said F it, ended up pretty good
Personally when I did the flashlight thread(https://bobistheoilguy.com/forums/threads/fram-endurance-flashlight-test-in-canister.386911/) I removed the Endurance from my car immediately. My daughters car finished a 5k oci. Never bought First Brands filters again.
All that matters is doing what you are comfortable with.
Yes, it's easy to point and say I knew already but I don't believe @Glenda W. meant it like that. More along the lines of learning just as you did. Now you know and there are still others that will run them still. Although those numbers are dwindling we all get to vote with our dollar how we see fit. Happy to hear you have some Carquest in your stash now and you will hear all the praise since they are great quality.
It's all a Russian Roulette game with the ruffled leaf springs, so I just don't buy that design anymore. Some can be way more ruffled than the next, meaning the amount of dirty oil bypassing through the leak gap can vary. To me, I want zero or super minimal dirty oil internal leakage going on. If it doesn't bother you, then just continue using what you have. You won't know the level of the leak gap on each one until you cut it open after use. That's not what I want to find out after already using a filter. If you have a bunch all made around the same time, and the used ones show to have smooth leaf springs and a good leaf spring seal, then chances are the rest of them will be good too.
I dont buy them either, that's why I stocked Carquest Premiums for the next few years for my cars
That was last Fram from my stash, it would be a waste to just toss it into garbage with no use.
I have started to pay more attention to louvers (vs. holes) in the oil filter tube. Post 1 picture 3 shows that the lovers seem to face in opposite directions every other louver....this could be mistaken for louvers that aren't open (I think).
All in all, going to louvers from round holes that can be seen was not a good thing. Was this another 'upgrade' done to save money?....why else would they do it? I think I'm going to start avoiding louvered oil filters.

In this shot it's easy to see the ones facing down towards the dome end are also opened up. If you look down a center tube and see the louvers facing up towards the base plate are opened or not, then the ones facing downwards are going to be the same. I've never seen a case where one side is open and the other side closed, or vice versa.
That's what I thought....I do think louvers were a step in the wrong direction....but that seems to be the norm these days. It's all about the 'Benjamins'....Could cutting round holes really cost more than cutting louvers?
With louver formation, there is no waste metal to take care of like there is punching out holes, so yeah probably a cost cutting move.
If you want nice holes in the center tube, go with the PGI made filters, like a Carquest Premium, Premium Guard or MicroGard Select. Like this one ----> link: HERE
ECORE probability cheapest solution and also efficient how much oil can pass through
Why many still use metal, probably cost of redesigning and cost of manufacture restructuring
I would prefer ecore as that metal ones can still have metallic shavings left as result of poor quality control as was seen in FRAMs
Yes, if the eCore center tube is done right (small enough windows to prevent media blow through) than it's a good solution. The reduction in dP of an eCore vs a good louvered center tube, or one with lots of holes isn't going to be much - hair splitting level of difference.
I ran the dP vs flow of a Fram center tube that had lots of small 1/8 (0.125) inch diameter holes, and the dP was surprisingly low. Even if the eCore was half as much dP vs flow, half of almost nothing isn't much of a gain. The base plate had much more dP vs flow than the center tube.
