ACDelco PF1237

[TheOilWizard]

This filter was in a 2013 Nissan Rogue for 5 months and approximately 5,000 miles. There were tears in several locations, but I only included a picture of one.

The ADBV was very stiff, although it has been sitting for the better part of a year after service. I cut open my other PF1237 with similar usage and it also has tears in the media.

No wonder . Those pleats belong on a accordion.
Thanks for the cp...

Shame. Guess it's time to try another brand. Thanks for sharing though.

 

[DuckRyder]

That does not look good at all...

That must be the low restriction model of the filter line.

Thank you for the cut and post

That tearing is awful! And it's a shorty filter too

Next time, get a Fram 7317, or the Wix 57356XP (Napa Platinum 47356)

Does anyone know who makes this filter?

Interesting. It is a bit unusual to see this on an AC Delco filter.

Thanks for the Cut & Post.

Could the tears be from sitting around for a year or did the other PF1237 with similar use and tears not sit around that long?

Good question.

I'm looking through my service records -- one was removed from vehicle on 10/17, and the other 6/18. I didn't label them, so no way of knowing which is which. Seems to me unlikely they would tear from sitting there, especially for such a short period of time.

The pleat with best lighting appears to show an unusually large accumulation of carbon captured by the filter. Is that real or illusory? If it's real, high pressure differential due to clogging might go part way to explaining the tears. (Not entirely, since the bypass should open before the media tears, even if badly clogged.) The skimpy overall media area didn't help.

What was the oil grade used, and coldest start temperature?

I suspect what you're seeing is dry oil as the filter had been sitting for a while after service.

No way ... there needs to be a force on the pleats to cause tearing. Force from delta-p created by oil flow. Super wide pleat spacing combined with oil flow equals force on the pleats. If the media can't take the side ways force, it tears.

zee09 is right. Those pleats belong in a zydeco band. Very disappointing in a filter I've used before.

CR94 is likely correct. If indeed the filter is loaded to capacity, then the delta-p would increase. If the media is weak and brittle, then the tear can occur. CR94's questions are very relevant because high viscosity plus low temperature will also increase the delta-p.

ZeeOSix is also very correct.

Both of them?

This is why I always run an oversize filter on an automotive application - to reduce Delta P.

More surface area = better flow = less restriction = no tears in the media

All the GM fanbois crying about making sure everyone runs a 22psi bypass valve can probably expect to see a lot of torn media from various brands.

ME? . . . . I would MUCH rather have a 7-8 psi bypass valve................................... than torn media

At which the bypass valve should have saved the "hide" of the filter. I had a fully clogged filter, with thicker than spec oil, in the winter, and the media was intact. There is no excuse for a tear, ever.

Look like Champion made to me?

There have indeed been examples of torn Champion Labs filters on here before.

I don't recall who else uses that spring poppet bypass like Fram uses.
