Amsoil EA15K09 Cut Open 10,000 miles

[GenSan]

Used on a 2024 Rav4 Prime XSE for 10,000 miles and from Sept- Jan. I drive it aggressively on a daily basis. It had 3 oil changes on it from AMSOIL Signature Series 0w16/Mobil 1 ESP 0w-30/Frankenblend 0w-16's of Ravenol, Amsoil, Idemitsu.

Stout little filter that I would confidently run to its rated 15k miles next time. Could most likely even make it 20k miles on a several oil changes and a clean engine but it's just too tiny.

The bypass valve is one interconnected piece with the coil spring and leaf spring which I like. Very firm and positive spring actuation when I pushed it in several times.

No metal to connect the pleats but it did look like it was intact and was not a weak point in the pleats bursting at the seam. Plastic core looked sturdy. I didn't see any excess globs of glue on pleats and metal ends.

Thanks for flashlight inside. In your first picture if you'd taken a pic right in-between the end cap & leaf spring we may have or not seen light coming through. That is what is commonly referred to as the "Flashlight Test" around here.

No leaking light to report and the leaf spring sits very flush with metal end cap.

Leaf spring looks pretty ruffled in the 2nd photo.

It does but I saw no light leaking through and you can see that it also has a recessed stamped lip to make the fit even tighter.
No issues with unfiltered oil seepage on this can from what I see on this filter disection.

If the leaf spring has "nubs" around the area that fits down into the end cap hole, that's what keeps it tight, but that doesn't add any sealing ability. In that case, all the sealing is between the area that's ruffled and the end cap.

Like I said I saw no light leaking so take it for what its worth.

If there are no "nubs" on the leaf spring or on the inside of the end cap hole, then it might seal well if it's a tight fit. But if there are nubs and the leaf spring is ruffled there's going to be some leakage, regardless if you saw light or not. If the only "sealing" going on is between the ruffles and end cap then there are gaps for leakage. Are there nubs on either the leaf spring or inside of the end cap hole? Can't tell from the photos.

Just another Pic this time in a pitch black room and my LED flashlight on max lumens.
Absolutely zero light seeping through the leaf springs. The metal end cap is hot to the touch already from my light. Light is at 900 lumens and is a Lumintop ToolAA 3.0.

Looks like a gas burner on a stove top! I hope the ruffles gazpacho will accept your photographic evidence, lol.
^Perfect Seal

Another angle and the setup.

 

[ZeeOSix]

Let's see a clear shot of the end cap without the leaf spring, and the leaf spring area that fits in the end cap hole. Still don't know if this filter has "nubs" in the hole or on the leaf spring, or none at all. Maybe they changed the design to make it seal around the circumference of the hole instead of on the ruffled surface area. Like said before, if the seal is just on the ruffled area, it's going to leak, even if you don't see any light because of how the leaf spring fits in the end cap hole. Need better clear photos to see.

Zero light leakage in my book so I'm chalking it up as zero unfiltered oil.

Not enough evidence for me. Like said, if the "sealing area" is just the surface where the ruffles are, then it would have to have some leakage, even if you don't see light for some other reason that doesn't let the light get to that area. There can't be a "seal" if the two mating surfaces aren't smooth ... and those ruffles aren't smooth. But since you won't give an answer to the nubs question, then no real conclusion can be made on where the actual sealing is taking place or not.

Something is different about the way that leaf spring seats, maybe champ figured it out?

Maybe ... that's why I need more info to verify if it's sealing regardless of the ruffles on the leaf spring.

"Maybe", possible. But if true and based on majority posted anecdotes, in my observation an outlier 'at this point'. All that said, WCW has relatively recently flashlight tested a couple AC Delco filters specifically, and both passed.

Need a pic of the leaf spring from the other side that seals against the end cap to see if there are ripples

Can see the ruffles in photo #2. If the ruffles are on one side, then they are also on the opposite side since it's a sheet metal stamping.

GenSan,

Thanks for posting!

By the way, did your engine implode from using this possibly imperfect filter?
