Correct metal filter housing for 2024 SR5

I barely tighten mine and occasionally on the next oil change it will take a breaker bar to loosen it. Not sure why that happens, but it does.

 

I've noticed the same. O-ring swellage?

 

I have a couple of theories. I think I’ve noticed this problem the most when I used aftermarket filters that came with their own o-rings. That can maybe explain the situations when it’s super hard to untighten all the way until the o-ring clears the barrel surface. Whether it’s swelling or if it’s slightly oversized in thickness of o-ring, or outside diameter of 0-ring, I’m not sure.

Then their’s the times when it’s hard to break free (and unscrews fine there after). I’m not sure about this idea either, but i think it has to do with the fact it’s a coarse thread with lots of surface area. I think the consequence of that is that a little tiny variation in tightening torque can lead to really big differences in how easily it will break free later on.

Also, not sure if friction or dimensions change due to the engine temp at the time removal plays a bigger role with threads this big.

Just spitballing theories though, since I’m not inclined to take detailed notes after all those variations lol

 

I say O-ring friction. I used to build scanners that had O-rings in the bearing bores. Over time the bearings will "stick" in the bore when you go to disassemble them. Kind of the same thing going on with the filter housing. It takes more force to remove than it does to install. Even though you lube the O-ring it dries out from time, heat/cold cycles and the fact it is slightly compressed.

 

I noticed with the plastic housing there is quite a bit of resistance the entire way both tightening and loosening.

With the metal housing, it spins freely both ways until the very end where it's almost a hard stop and needs very little torque to tighten to spec.

 

Has anyone been able to do a visual comparison between the Lexus and Toyota version of the metal filter housing?

 

I got the Lexus version in today and it's identical to the Toyota one except the tube is the correct length for the 4Runner (also the Lexus version doesn't come with the small drain cap on bottom), reuse your old one

It's a Lot cheaper to buy the 15620-31060(Toyota version) and swap the center tube from the one out of the 4Runner vs. paying $88 for the Lexus version


As for spring rate, it should be the same thing. If you research what the Lexus housing fits, one is a Lexus IS350 which was using the 04152-YZZA3 filter, then they switched it to 04152-YZZA5(same as the 4Runner), seems like the A3 filter is Identical to the A5 filter, just the A5 filters come with the plastic drain part where the A3 filters did not come with that.

Bingo! The plus side of the 'O' ring taking a set is that you don't have to worry about the filter or housing loosening between changes. We don't have to safety wire filter bowls on modern aviation jet engines because of this.
