Cut PureOne PL26451, no drama

[AuthorEditor]

Changed the oil and filter today on a 2008 Chrysler Sebring with the 2.7L engine. Mileage was just shy of 6k with a 6-month OCI over the winter. Combination of mostly shorter trips, with the occasional longer run. The metal end caps came off with little effort, but the glue seemed solid holding the pleats in place, even on the side that was wavy. This filter hangs absolutely vertical with the hole side up, so it does demonstrate how the waviness is related to the seam position and the fact the pleats are more widely spaced there. Again, media felt strong and solid. Could not detect any tears or holes no matter where I prodded. Replaced with the same filter purchased in October 2015 for another 6-month OCI.

Made September 29, 2014 I see and looks good

Another filter that looks great!

Thanks for the post!

Shine a strong light down the center tube and see if there are any leaks.

Hard to get a photo of since I didn't want to use the flash. Shined a flashlight up the center tube and couldn't see any holes.

The filter did it's job wavy pleats and all.

Thanks for the well done cut and post.

Don't think I have ever cut open a PureOne that didn't have wavy pleats somewhere. Seems to be a "feature" of them. See the same thing on the FL820S Motorcrafts too, but not on the big FL1A filters I use on a marine diesel engine--they come off nice and even.

I have used more than a few MC FL820S filters. One developed tears top and bottom near the splice. This make and model demonstrates wide or uneven pleat spacing near the splice. When I see wavy pleats, it is a sign the media is loading up with dirt and delta P across the filter is increasing. This is a precursor to a torn filter. This makes for polarizing discussions.

The metal disks were supposed to be stuck to the glue. That's a major manufacturing defect. Someone isn't testing product.

I would describe them as "stuck" but not very well. I was easily able to pull the metal disks off, but only a little glue around one of the edges came off with it. You can see it on the disk to the right in the picture. Not disagreeing that they should stay stuck on, but it is hard to see how it would have impacted the function of the filter since the pleats were all stuck properly in the glue and felt strong.

As to the wavy pleats indicating a problem with dirt loading and an increase in pressure differential I have yet to take a PureOne or Motorcraft FL820S off of any vehicle without there being some wavy pleats, usually around the seam area. Maybe that is a flaw in their design and construction, but I have never found any holes or tears either.

Got the job done, but not very pretty. I'm not a stickler for perfectly straight pleating and even the highly respected German made Mahle spin on posted here exhibited post use wave. No effect on function. That said, seam pleat area in this one doesn't look good. Could be more media needed and/or the width of the media and assembly compression has caused the bend. IMO, a point of potential weakness.

As for endcap, it was attached and potting(glue) intact. And even poppers as long as potting intact and leaf spring functioning as designed, not an issue.

So no drama as in failure, but doesn't look as good as the other P1 you posted yesterday.

Thanks for c&p.

you went through all that trouble.. how about a few more pics

 

[AuthorEditor]

What do you want a pic of? Not much else to see as far as I am concerned. I usually focus on anything unusual or not like it should be, like the wavy pleats sections. The rest of the pleats looked normal. Nothing to see down the center tube--holes, not slots.

Yeah, it will be either a pre-failure discussion or a "see, not tear" discussion

If this was a metal seam, I think it would have given up the ghost. Having a flex at the seam tend to make ugly wavy filters compared to failed filter in most cases.

Looks great.

Thanks for posting.

If you paint the can orange, all the suspected holes and other anomalies will suddenly disappear.

Orange paint can fix a bad filter every time.

This is hilarious.

I ran a PH16 that looked much better than this and keep in mind it's an entry level filter.

Some folks (who you never see in the filter forum) even chimed in saying how they don't understand how anyone could use one.. Yet somehow this mid-grade filter is okay?

Like I said, it's hilarious. I'd love to put a like model TG or WIX against this pile.
