Dang looks like they changed the forming process altogether
Fram Endurance Flashlight Test in canister
- Thread starter Glenda W.
- Start date
Fram ultra xg7317. Same model as endurance fe 7317. When I cut my titanium open I will fit the leaf spring into the endurance to see if it seals.
Probably to save 2 cents per stamping ... lowest bidder, who knows where these come from. Could even be outsourced. Nothing good stays the same.
I’m thinking as we drive how the ripple chip ones ARE formed. That can’t be a clamping surfaceProbably to save 2 cents per stamping ... lowest bidder, who knows where these come from. Could even be outsourced. Nothing good stays the same.
Wish I had one in hand
So drawn free…after stamping out?? Can’t make sense of it
Maybe the guy running the leaf spring stamping machine use to work in the Ruffles chip factory.
That would explain the greasy salty prints!
Ok help me out here.
I reviewed the excellent picks at the start and I’m puzzled. Oil was poured onto the bypass to observe any leakage. It “appears” the leak is only around the edge of the plastic valve and not where I would expect..,,, at the base where the tube butts up against the metal plate.
The first pics are show oil poured and resulting leak around valve.
The bottom two show where we would expect to see most leakage and I see little or none?? It’s obvious some oil got into the gap and onto the base and tube,
But most is at the plastic valve head itself.
That area has nothing to do with plate/canister gap!?

That bypass valve "leaf spring" is more of a bracket than spring and does little more than fill space in the dome end of the filter. Keeping the media in place, but does not coil or apply similar pressure of a coil spring. It's a crappy bypass valve design that I would try to avoid using. I prefer a dome end bypass valve built into the top of the end cap, or the Motorcraft input bypass.
Sure the leaf spring compresses slightly and puts some compressive force on the guts of the filter. Nothing else holds it all tight together.
Seems to me if it did then hand pressure would close the gaps. That doesn't appear to happen. The gap is the same whether sitting on top or or being compressed with hand pressure.
That's already been explained why multiple times in this thread.
Thanks for posting the pics again
Looks like the starting sheet was/is thinner and only only drawn in one direction and “folded” back so to speak. And really clumsily causing all manner of deformation
Honestly this process should not have been approved!

Mid 2022?? Ultra XG with gasket.
But if it leaks around the valve itself as indicated in my previous post, does it matter?

Can't tell where the oil was leaking at in your post 427. That's a Ruffles style metal-to-metal leaf spring, so it probably leaked oil from there and migrated to the bypass valve down the dome shaped area the valve seals to. I tested a Fram bypass valve like that one and saw no light leakage. Maybe I'll do a liquid test too.
The OG Ultras with the fiber gasket in the end cap won't leak at the leaf spring either. Motorking said the OG Ultra was 80% @ 5u, and without that leaf spring seal I doubt it would be that good.

Z6 is right, the coil spring has more travel to hold the element, this is the spring up that you see when you cut a filter open, the 'leaf' spring exerts about the same pressure, but it has less travel.
@Glenda W. … I assume no oil was flooded in the actual bypass valve area if you were looking for just leakage around the leaf spring seal. This was questioned in post 427. Can you please elaborate.
It appears oil poured onto the valve spring directly flowed past the valve. No migration from the lower gap.
I think the engineers at Fram thought the gasket was warranted or they would not of done it, car manufacturors never add an extra part without a true need for one.
Fram was going for an "Ultra good" design with that version to maximize efficiency and holding capacity. Ascent's ISO 4548-12 efficiency test showed that.
No oil was applied to the bypass valve area. It was carefully applied around the end cap and gap areas. Exactly a thimble full was used. The oil immediately went through the .75 x .020” gaps.
The first picture was with the bypass valve toward the sky. Gravity causing oil to come through the gaps toward the camera.
The second picture is after I flipped the filter over so the bypass is toward the ground. Gravity causing the oil to go away from camera back toward the gaps.
