Absolutely terrible.

Don't have much info on its usage. First oil/filter change by me on this vehicle.

On the bright side though, the uh... anti-bypass valve doesn't have ripples!

LoL ... plus, it's a metal on fiber end cap seal ... better than metal on metal.

What was so terrible about it? Looks to have the Champ Labs combo valve base plate.
Maybe I shouldn't be so hard on it... but small cellulose filter with no bypass, just seems unnecessarily cheap and unlikely to be worth the few dollars saved.

There is another post of it by someone else here:

It seems to have lost the metal caps since that post. Also, it claims to actually be a synthetic media. They have claimed that as far back as at least August 2020.

I would have sworn cellulose because of the feel and how it tore, but let me go take some pictures...

Given the unknown prior history, I would not blame the filter condition on the filter itself. I have used plenty of E-Core based filters within recommended change intervals and none of them over look that bad.

Yea the used state of it isn't a concern. Who knows how long it was in there.

What engine is this one? Must be one with the filter bypass in the filter mount or block.

You're only allowed to burn ADBVs ... not media. 😄

2UZ-FE in a 2004 LX 470. From what I can find, the 1UZ-FE doesn't have internal bypass. I don't know about the 2UZ-FE though.
 
^^^ From post 2. That filter has the combo ADBV/bypass valve base plate.
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 contamination when bypassing that happens when the bypass fluid passes over the outside of the media and picks up debris settled in the can.

I withdraw the 'absolutely' part of the terrible though lol.
 
Yeah, I dont trust the combo valve design either. Give me a good old fashioned metal coil spring.

FYI ... search for Patent # US7175761 for details.

Item #32 in figure below is the piece of the rubber combo valve that flexes and opens up when the dP across it is too high, and the oil flows through hole #34 past #32 and into the outlet hole in the base plate - that's the bypass flow path.

Thanks for sharing the zoomed in pics. I take it you're not buying another one of these. 😄
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 bypass pressure is reached.
