Bosch D3330 - Cut open, no tears but.......

[paulo57509]

This is a Bosch Distance Plus P/N 3330 out of the LS400. This filter was in service for 5,889 miles with PP 5w30. It was replaced with a Denso filter.

After cutting the can open I put my finger in the center hole to remove the filter, the whole metal top of the filter came off.

The top came off as though it was just placed on top of the media. I don't know if I would categorize this as a failure. However, it's still kind of unusual.



The bottom end is attached (glued?) securely to the filter media.

Date code:


There's also a few pieces of what looks to be the stuff the filter media is glued to caught in the pleats:

i stopped using anything purolater like many did. Wix makes a good oil filter if you could get them at a good price. Also fram ultra seems to filter very well and is made nice. They tell me it flows nicely also. This is my first time using a fram in many many years but this ultra looks good i will be cutting it open in 10 or 12,000 miles and will post everything for everyone to see. The way she puts mileage on it should be soon...lol

Fiber end caps please? Anybody?

 

[901Memphis]

Yeah usually the end caps pop off pretty easy.

Not on Fram
The fiber endcaps are on to stay.

It's funny how everyone hated fram for that reason until filters like purolator started having a lot more issues that the glued together Fram filters. I think it's interesting to watch peoples preferences go in shifts according to what is popular with the majority.

I really like the Fram Ultra, It's built like a tank. I have also always said the OCOD wasn't nearly as bad of a filter as people made it out to be. It isnt a great bargain, or beautiful to look at when cut apart, but it is pretty durable. It is definitely more durable than many give it credit for.

It's easier for me to accept fiber end caps on filters. I've been using them since our '98 528i. Mahle cartridges utilize them, and if you prefer adhesive/potting material or whatever then a Mann cartridge. I've used them up to 13k/ 1 year and never had a problem.

 

[dlundblad]

No harm in the end cap falling off. The internal spring keeps everything compressed together.

As said though, this does make accepting fiber end caps much easier.

The adhesive is what would bother me. Since its in the media, that stuff was more than likely floating around in your engine. The filter did its job, but it could have clogged something too.

 

[Nate1979]

Yeah, just another example of the possible side effect of a failure. In this case the adhesive possibly getting into the motor.

Fail!

 

[daves87rs]

Does not look too bad...

 

[OneEyeJack]

I think the filter manufacturers have figured out how to keep the adhesive where it belongs.

And if you don't like fiber end caps what do you think they are connected to? Maybe more fiber.

What's really needed is some published spec's for new car applications and filters that match those spec's. They do it for engine oil. It can be done for engine oil filters, something very specific.

This "meets new car warranty requirements" is a bit vague.

The end cap shouldn't just pop off. That being said the glue/bonding looks solid on the filter media and the pressure from the leaf spring should keep the end cap in place during use.

This.

And same phenomenon shown on the well respected Denso First Time Fit oil filter linked.

And the pleat end area covered by endcap shown with spring pressure is significantly greater than that on fiber endcap offerings designed to be sealed by leaf spring pressure over a narrow area.

Other than the super strong can, I can't really figure out what is so great about the Distance Plus-too expensive, too much Purolator, no full syn media. This one has decent media, but the glue stuff floating around is bad news, esp. if a bypass event occurs. Not good AT ALL!

The Denso has a shallow raised ring to seal the center tube, it can be seen on the picture. The corresponding indentation in the potting material shows a good seal was made. The Bosch is flat, oil can pass easier. Unless the center protrusion fits tightly into the center tube hole, which apparently it didn't. The Densos with no end caps seal at the center tube too. I used to use many Malaysian made Union Sangyo filters on daughters Maxima, every detail looks the same as on that Denso to me. I believe as they expanded production to more non Toyota sizes in the Thailand plant, these older ones with end caps are phased out. I think they rebadged Union filters when they have end caps. I have a new 150-1003 here that I will cut open to verify what I am saying, as this size also has been shown with end caps. Mine on the box says made in Thailand. I only have a hacksaw, I guess that will have to do as my exhaust pipe cutter doesn't go large enough. Then I need to figure out how to show pictures.

^^^ You're entitled to your point of view as I am to mine. I agree with poster's conclusion I quoted. Same phemomenon with similar construction principles, potting designed with adhesion to metal endcap. Same result on both the Denso and topic'd filter regarding specifically the endcap falling off on filter and dissection. As long as leaf or coil spring functioning as designed to securely hold element, no oil bypass. Based on my reading here over the years, that too is the consensus of opinion.

Classic endcap construction is being compared here, ie., metal endcaps, and thus comparison to no endcap design is unrelated/irrelevant to the discussion imo. Different construction type. But since addressed, as has also been shown here many times, no endcap type filters test relatively low in efficiency as compared to majority classic construction filters from major manufacturers. End off topic portion.

It looks like a repainted AC DELCO...

I would just switch to another filter.

 

[ZeeOSix]

End cap popper syndrome.

 

[Nate1979]

If there was no problem how do you explain the adhesive caught in the filter media?

 

[Yah-Tah-Hey]

I use Denso oil filters and have seen the end cap loose on one filter I removed. I don't see this as a problem.
