Dismayed With Pure One's

[wrcsixeight]

The glue did not adhere to the metal endcap. I bet a whole batch of endcaps were not properly washed before assembly and the glue never formed a bond. I bet the filter was still filtering fine since the spring would have kept the endcap pushed against the media/glue.

I have never seen that black colored glue before, more the amber color on every classic I've opened.

I too am dismayed at this. I was a classic user. The one time I used a Pureone the lifters started ticking on startup and I removed it shortly after and never used them again.

I'd let Purolator know, even if you do not care to ever run another one

All the Purolator Classics or PureOnes I've seen cut open have the black glue.

Strange ... lots of uses usually get rid of start-up rattles by using a Classic or PureOne. Guess every engine is different, or maybe you got a bad filter that time.

I know the Ultra has glued on metal end caps,all quality oil filters have glued on metal end caps,that why I dont use the OCOD.
I understand problems can be had with any company but this then the over spray on the next one I looked at tell me their QC isnt what it should be.My $ will go else where.
I threw the can away with the build codes on it a while back so telling Purolator about it isnt going to do any good it they cant trace it. This filter was bought close to a year ago so most of that batch would be sold by now. Live and learn.

This is one of the reasons Fram claims they like the fiber endcaps, they state the glue adheres to fiber endcaps better than metal.

I have never glued an endcap onto an oil filter myself, so I can neither support nor refute that claim but having worked with other materials it does make sense.

The type of media along with the wire backing in the Ultra forces Fram to use a metal endcap for those. They don't use it because they think it's better, they use it because it's the only option for those design materials.

But I think this is a mighty rare whoopsie for a Purolator too. No need to throw the baby out with the bath water.

Perhaps this glue is black. My last Purolator classic:

I did not open the Pure one that caused the lifter ticking on startup my 318 and never tried another. That was before I developed my chisel opening technique.

I think I'll just keep using the m1-301 when I can find them on special.

I would call purolator and if they handle the problem well I would give them another shot. Plenty of great people and companies make mistakes let them make it right before you write them off.

 

[dinkydau]

The other P-1 that I have with the over spray I went out and cut it open and end caps are tight and glued right,then I started looking at the over spray and its on the inside on the center tube. The clean side of the filter! So what do think would happen if that gritty stuff broke lose and went thru you engine? Im trying to give them the benefit of doubt but this is to much. Im through talking about it.

[Dakota1820]

Still calling them is one step toward helping create better qc. And i doubt a puro filter has ever hurt an engine. And considering an explosion happens on your pistons almost non stop its silly to me to worry about a filters overspray. Jmho.

 

[ZeeOSix]

I've heard of complaints of yellow paint on the base plate by the gasket, but never any over spray down inside the center tube.

 

[jkhawaii]

well, before it was cut open there was a spring holding it together.

Manufacturing failures can happen to any process from any source.

Sad that it happens, but true.

People often berate Fram for perceived problems such as QC effectiveness, but I suspect this happens to all brands to some degree. We have seen Wix failures at times. I've seen a M1 filter not crimped well and leak at the seam. I've seen a K&N nut twist off with relative ease. Examples are there if you look with unbiased eyes.

However, the VAST majority of product is tyipcally well made. While mistakes can happen in every situation, there are companies that have a propensity for issues, and those that trend towards success. Nothing is 100% "pure" in success, but there are shades of gray in each story.

I ought to know; I do Statisticial Process Quality Control for a living ...

Well, this is obviously not a "quality control coup" for Purolator but the potting coming loose from the metal cap is not a always a huge issue in terms of filter operation, as the spring will hold the unit together and likely it wasn't bypassing.

I learned this in my tour of the Fram test lab, where they had a Puro with the metal loose from the potting. The tech guys said this wasn't much of a worry as long as the media stayed potted and the potting stayed intact but they did point out that getting the potting to adhere to metal is the age-old problem with metal endcaps.

Of course, they took delight in pointing out that the potting sticks really well to fiber endcaps, so that's a problem FRAM doesn't see. After seeing that, I went home and pulled out a new P1 I had virgin autopsied a couple of years ago and with only a little effort, I popped one of the endcaps off the potting. I have included a mild attempt to pull the endcaps off as part of my inspection for autopsied filters. I once found a used Wix that was loose about half way around but I really don't know how common or prevalent this is.

Much as it pains me to agree with FRAM,

I do agree with that statement.

Most cartridge filters have no end caps at all, just glue, and they seem to work fine.

 

[Virtuoso]

Interesting point about the adherence of the fiber endcaps vs. metal; one I had not really considered before.

I've personally never cut a filter that had an endcap loose, but I did cut a Motorcraft that wasn't glued along the media seam once. Bad apple in every bunch I guess.

 

[Sayjac]

Even if the endcap fell off upon dissection, doubtful there was any leakage with the pressure from the leaf spring on the cap. I don't see this as much different than the centertube of an orange can covered only by a very narrow section of the fiber end cap and held only by leaf spring pressure, no glue at all. Those are claimed not to bypass, why would an even wider section covered by an end cap with leaf spring pressure do any less. And obviously there is glue, the blackish elastomeric material is clearly visible in the pics.

Actually surprised the OP hadn't already moved on to another brand as this finding was posted last month bypass location thread.

As said, I've used many Purolator filters and Purolator made fors like the AAP TG and never encountered the OP issue. And if fiber is somehow superior for this reason, why haven't Champ made filters such as M1, K&N and the non ecore STP's gone to fiber endcaps. Fram and Champ now both owned by Rank, if fiber is somehow superior one would think that change would be immanent. Not very likely.

All that said, the OP should likely move on to another brand if one filter out of a vast majority including many posted here with no issues is causing such dismay. Lots of other brands out there.

 

[LeakySeals]

I just looked back at many filter autopsy's. Whats common: The paper end-capped filters were inspected to death. Tugging and pulling on the paper. Inspecting every single glue seam. Peeling back, prying, making every attempt to find a problem. The metal end capped filters got a complete pass. They all "looked great!". New or used, not one autopsy did anyone actually pry or attempt to separate the metal end cap to see how it adhered to the media. Not one. Just as the paper end cap was assumed bad, the metal end cap was assumed good. After seeing this I'm curious what the glue does on non-porous metal after being exposed to several thousand miles of motor oil and heat. For now on when somebody posts a filter autopsy we should ask this question.

I'm saving a 2X OCI Ultra that will have 14k total on it for autopsy. It has metal end caps. When I open it I'm definitely going to try separating the end cap, see how hard it is.

I, too, agree that there are benefits to the fiber-cap philosophy. Conceptually, it does make sense.

However, I do find it a bit ironic that the Fram top-tier products use metal end caps; perhaps in a nod to the (if even mistaken) notion that metal is "better". Makes me wonder ...... if the fiber-cap does have advantages (such as adhesion), then why not "upgrade" the concept of the fiber cap to a "thicker" fiber cap in the Ultra? Kind of the best of both worlds, so to speak.

No irony at all, simple black and white engineering fact. The wire mesh backing necessary for a lofted syn media can't be reliably attached to fiber endcaps, so they use metal.
