Stocked Up on Fleetguard LF17531 (Louver and Adhesive Pictures Inside)

[mphilleo]

Well folks, I've looked down the rabbit hole for awhile but now I've gone and jumped inside it.

With the help of @NashNative I was able to determine which filter I could use in my application in terms of cross reference and dimensions. After a lot of calls and sleuthing, I found local source for the LF17531. Given the current state of things, and the fact that the list price was in pretty reasonable in my opinion, I stocked up for several OCIs. They seem pretty beefy for the size, weighing in at 9.11 oz (258.33 grams) for a 4" filter, which is definitely satisfying. The louvers look great too. Having never bought Fleetguard filters before, I don't really know what's typical for construction and consistency on these. So I figured I'd share some pictures down the center tubes with you. Hardly scientific or indepth but it's interesting to see what a filter is like across a larger sample size. To be honest, I have some concerns about the excess adhesive coming from the end cap onto the BPV. You'll notice one picture with a strand of adhesive across the bottom (6th picture). Feel free to set me straight as to what's normal or acceptable.

You can't use filters with louvers! They will cause turbulence and impede oil flow to your bearings, starving them of precious lubrication and your engine will explode.

I don't mind these louvers, they look pretty good. I'm wondering more about all that adhesive...

That's the standard method to seal the media to the end caps. There is a lot more in the filter that you can't see. I'm not sure what the glue is, but I've never seen any degradation, even after extended OCIs.

Thanks for the input. I'm debating taking a tweezers and attempting to remove that strand of glue or whatever it is, or just bringing the filter in for an exchange.

I would be very surprised if you can grab the adhesive with tweezers and remove it. Try it and see what happens. I think you'll find it's stuck like it's welded.

Oh yeah, that dark gray stuff isn't going anywhere, I won't mess with that. I'm talking about that odd thicker strand that looks almost like hot glue across the bottom in the 4th filter picture.

Louvers look good. I would have ZERO concern with the adhesive. I would rather see that, than not enough. Anyone who is concerned with louvers over holes doesn't understand the orifice equation, or positive displacement oil pump flow.

Very cool to see...thank you for your business! Where did you end up purchasing from?

Absolutely, hard to argue with the quality and value aspect with these filters. I got them from the local International dealer here in Bismarck. I wouldn't have thought to check them if it weren't for the handy locator on your website. Thanks for your help.

Objectively speaking, should I have any concerns with that long strand of white adhesive across the bypass valve in the 6th picture? I'm debating getting an exchange or trying to carefully extract it.

Also, I'm guessing the anti drain valve is nitrile and not "black silicone"?

Let me snag that photo you took and share with our warranty crew to see if they have any concern with it or not. I'll keep you posted.

I'll ask about the anti-drain valve too. In my own ignorance, I notice people always asking about that on here. Is there something about nitrile vs silicone that has people frazzled? I've never run across that concern specifically in my 9 years here honestly.

I believe nitrile has a tendency to become stiff over an OCI. That doesnt happen with a silicone ADBV.

Get a small wooden dowl or similar and see if you can break that glue strand off and shake it out or vacuum it out. The glue job looks pretty sloppy to me ... other filters don't seem to have that much glue slop all over where the center tube meets the end cap.

Thanks, I appreciate it! If you do go to the trouble to check with them (thanks again by the way), would you also share pictures 3 and 5? Like I said, I have no problem with adhesive overflow from the end cap, but I wonder if those smaller flecks of adhesive could become dislodged and become an issue.

The main concern with louvers is ... are they formed correctly so they are visually opened more than a mere hairline slit. The louver forming can be all over the map, and if someone doesn't look and installs one with mere slit openings, that can cause a lot of delta-p across the filter and cause it to go into bypass way more than it should.

How about this one ... NO openings on the louvers, just bumps. Total failure on louver forming.

Not opened enough.

Opened well.

There's only been one "black" ADBV (it was actially a greenish black) proven to be silicone ... that was on a Toyota Denso.

Yep, seconded. Some of my pictures aren't the best, but on these filters, the louvers look good.

Shoot me an email when you get a chance and I'll talk you through a couple of options here: [email protected]

As @travis8352 noted, it's the tendency for nitrile to get hard during an OCI, also, it gets hard in the cold, so the ADBV simply doesn't function as well. That's why the premium passenger car filters all have silicone ADBV's. Would be a worthwhile upgrade for the premium Fleetguard filters that have passenger car applications, IMHO, like the the LF16002 for example or the LF3487.
