Toyota oil filter light leak

^^^ All the brown stuff must be dirty oil trapped where the leak gaps were. 🙃
Imagine all the Lexus and Toyotas driving around with this ticking time bomb under the hood!!!
The amount of crud accumulating in all those cars is beyond comprehension!!
The horror!!!
😱😱😱

You still on the "Let's make leak filters great again" trolling campaign? 😄
Yes
Leak… Weak…Bleak … Very bad…
Leaky ..sneaky … even worse….
Leak very bad … in fact .. there’s nothing worse than a leak….why?
It leaks !! That’s all you need to know!
But wait! It’s not a leak after all!!
Why?
REDEMPTION!!
It stays within the filter stream and is transformed back to “unleaked”
I kid you not!!
Miraculous!!!

I think you've lost it over leaky oil filters. 🤪 You keep on believing they are great and keep 'em on your engine, not going on mine. 😄
 
Probably a big factor on why the Toyota filters aren't very high efficiency.
Toyota is so good at everything they do. I don't understand why they don't spec their filters to be 99% @ 20 microns, and award their filter contract to a company like Pentius. Perhaps it's their "B team" that is in charge of the filter specs.
 
Toyota seems to have discontinued the TRD line made by Champ Labs, maybe this has been for awhile. It was for racing and low restriction, yet had better efficiency than what the board believes the regular filters have.
Denso makes the filters and some quality issues have been shown here recently. If the resin is flat there is very little light leak. I opened one N1 that had a bump , a raised piece of resin on the sealing surface. That one had about as much like leak as a bad Fram.
They can’t know of that issue because the cans are sealed, sold, and that’s all they know. The only place showing the leak was WCW.

I see your point here @Ronn but when oil is bypassing the oil bypass valve by way of the leaky leaf spring seal, doesn't it make the bypass valve opening pressures at least inaccurate, or at worst, worthless? I guess, what I am trying to ask is, what is the sense of a bypass valve if the oil can just go around it anyhow?

Not to mention an engine continuously produces debris, so there will always be “dirty oil” bypassing the media with a leak. It’s a never ending cycle.

Now if there was a set amount of debris his theory would be correct and eventually all would be cleaned up by the media.

That’s proven by bypass oil filters cleaning diesel engine oil where soot is constantly making the oil black. Even a 90% bypass, 10% filtered, results in the soot cleaned out.

That's using a high efficiency bypass filter in conjunction with a full flow filter. Given enough time it will clean up the oil better than if there wasn't a bypass filter added, but it does the extra cleaning at a slow rate and still doesn't catch all newly created debris. Used oil with that setup is cleaner than without the bypass filter, but it's still got some level of soot because it's not a full-flow bypass filter.
 
Subaru Tokyo Roki filter media. People ooh and ahh about these. I guess lab test efficiency would be 20%@50 microns.
But don't worry, maybe the stuff that got through the first time might get caught the 2nd, 3rd or 4th time through. 😄
Keep in mind that the ISO efficiency test also takes into account how the filter sloughs off already captured debris - clearly seen in the Ascent ISO testing on the filters that come in with lower efficiency (Boss and Wix XP).

Filters like the Subaru shown below will have a higher propensity to slough off already captured debris as it loads up and the dP increases, or any time the dP spikes in use. But of course "it might get caught the next time around". This is another factor why a filter with a higher ISO efficiency is better.

One of my OTR trucks I had custom built years ago, a new Volvo OTR sleeper tractor with a Series 60 Detroit Diesel, I had a factory installed "Spinner II" centrifuge bypass filter installed on it. That thing did a pretty good job cleaning out soot. Here is a link: https://www.westatesystems.com/products/legacy-products/spinner-ii-fluid-cleaning-centrifuges/

True
But a 99%@20 microns synthetic filter (Endurance) will continuously trap ALL bypassed particles in range…so it really comes down to a brief DELAY of catching any particles that *MAY* be present in the small bypassed fraction of oil. The net result is still the removal all ALL particles in range. It’s just that a small fraction of particles are briefly “delayed” … “set aside” (we’re talking a minute?) before getting caught. This why we still see very good particle count results in used oil and what was also seen in Brand Ranks results as well.
 
I don’t have a reason to believe that I mean what proof do you have?
He has no proof that "Toyota knows all about it", and only believes that because of the basic belief that big leak gaps inside oil filters don't matter. It's more self justification of a flaw.
