Looks larger than that in the middle. The steel stamping isn't good, not allowing the spring to fully seat the disk. Cheap production quality.
Another leaking bypass valve

This brings a whole new definition to the term "bypass valve".
I will look into that in the morning. I believe the valve is hard plastic and it's hitting the support that holds the spring.
I was being facetious. But indeed low ruffles
Not the typical bypass (area) leak we've been seeing on this subforum. This one the actual valve not closing fully because it's seeming caught on something. As noted the spring enclosure supports seems to be the cause. Obviously a manufacturing defect. Fail. A Service "champ" it's not.
Doubtful as I have cut 2 open now
Lot Failed QC destructive test. Return it or ask for refund.
Oh, is the other one bad also? Guessing it would be.
Back in 2014 a one dollar factory installed china filter blew up my otherwise perfectly fine Nissan Versa Note with a 5 speed,. Really mad about that.
The first one was smashed in the mail so I cut it open. Thought maybe it's leaky valve was caused by the damage so I cut open a good looking one
And what did you see, my good man?
Here is a hypothetical issue. If the gap is there, the pressure drop across the filter is lower. If the oil pressure gage is way up at the intake manifold like it is on a Chevy LS engine, the indicated oil pressure might be HIGHER than than a filter with a perfectly sealing bypass valve. I have another posting where I have a higher oil pressure after putting on a Motomaster OE Plus which is made by Champ. I might have to cut it next spring.
The currant pic is the unsmashed one.its junk too.
Update: the valve is hard plastic and is installed upside down in both filters. Since there is no way of knowing which are ok and what are not looks like I have targets to shoot at.
The plastic valve has a step that would seal the hole if installed correctly.

Just. Wow.
I don't know if your post came across clearly. I see a ridge 0-0 just at the base of the portion that inserts in the center tube.

I'm thinking these were defective and caught by qc. Somehow they ended up on eBay.
I can't use them in good faith knowing what I found . Figure an hour of my pay at work thrown away

“ PULL !”
The disc is installed upside down. That ridge fits perfectly in the hole and would block it if installed correctly.
You don't think that having the oil go through there would push the disc up more and open the hole up even more?
Not really, the spring won’t open until a preset PSI range.
I would contact manufacturer and see whats up.
