Yea, if you check the second picture in the second post you can see how the tube protrudes when the media is against the ADBV. In the flashlight test pictures, I think the media happened to be pushed more toward the bypass side (it can move up and down the core a millimeter or two when assembled...

That, and the leaks lol. Seems worse than the Fram leak springs.

Everything so far was great, but now of course is the bypass. I cut viewing holes in the top of the case to inspect the bypass while still assembled Flashlight test revealed some small leak paths, but disassembly showed some bigger issues. The glue used at the ends of the media is too hard to...

Just purchased yesterday from Lexus dealership. Everything external looks great. Vacuuming out yielded no debris from the filter itself. ADBV and plate-can interface had zero leaking, up to the 30 PSI I tested. Gasket comes pre-lubricated and has a good profile for sealing. Burns with black...

They got me with those Black Friday deals... This thing should be arriving early next week! Still trying to get in a cross country trip before the year ends, so hopefully will be able to put about 7,500 miles on it in the next month or so.

He should also be pushing on the parts of the leak spring that contact the back of the case, not on the bypass valve itself. But to me it looks like it would leak regardless.

Yup, I agree. We'll see! I might be able to make it to the dealership tomorrow.

I see what they are going for, but it doesn't seem like it's going to be effective. Hard to say definitively just from the video, but here are a couple screenshots that show my main area of concern. I'm going to pick one up for myself though and cut a window in the top so I can see what it looks...

Just saw this video from Whip City: It looks like there is a very large gap between the metal core and the filter elements, and I don't see how the ADBV and (especially) the bypass are going to seal that gap. Could explain the poor particle capture results from the Brand Ranks test:

No, the magnets will touch the filter, although the point of contact is mostly just a line, and there is separation caused my the paint/coating on the filter. The magnets would also be in contact along an edge with the neighboring magnets. I think the whole idea of the MMR-style and other...

That's for pull force on a steel plate that is in contact with the magnets. The scenario with an oil filter is different for several reasons - mainly in that we're interested in magnetic field strength on the other side of the steel plate, but the magnets also aren't in full face-to-face...

I'll be making a simple retainer for the magnets, and I suppose I could also do some pull force testing once it's done. Looks like alternating to me, but should be pretty easy for someone who owns one to test. That's the plan! I've already made the design, just need to get access to a 3D...

What aftermarket filters would you say the typical Toyota filters like 90915-YZZG2 and 90915-YZZD3 are most similar to?

Nice! What grade are those magnets by the way?

This is the closest comparison I could find relevant to this application: https://www.duramag.com/techtalk/halbach-arrays/benefits-and-drawbacks-to-using-halbach-arrays/ Magnet size is about right with their .5" cubes. Halbach array had a bigger advantage when the gap between magnets was...

When using multiple magnets on an oil filter, there common orientation is a N-S-N-S-N pattern. The magnets don't repel each other that way, and the magnetic field strength is somewhat higher than if you managed to install them with the poles facing the same direction. But there is an interesting...

This one here: https://www.sae.org/standards/content/j306_199807/ I'm not curious enough to pay $57 for an outdated document from the last millennium. *edit* This seems to be the 2005 version, which has update notes that give a good idea of what the 1998 version was like...

I just tested a bunch of Fram filters and a lot of them had ADBV related leaking. The Ultra Synthetic seemed the worst, followed by the Titanium, and the Synthetic endurance performed pretty well. I also tested a Carquest Premium and it was probably overall the best of the batch. I only had one...

I will not lol. Yup, 28 is the usual ADBV where the gasket is pushed up under light inlet pressure to allow oil to flow fairly freely into the filter case, but not backwards. 32 is essentially the same thing, but requires a higher pressure to open so that it (ideally) remains closed until the...

Ok I see what you mean now. Interesting design, but with how nitrile ages in this application (tends to harden), I really don't trust this type of bypass to both stay sealed in normal use and open up at the correct pressure. With silicone, this could be good, and it would also prevent the excess...
