Problem with Napa Gold(Mann Hummel) 7356? Pictures

[Chris B.]

This is off my 2012 V6 Honda Accord. Filter has 5,000 miles on it using Mobil 1 0w20. I always use Napa Gold oil filters. This is the first time I have noticed a warped looking black rubber O-ring inside. Never saw this on the WIX version. What is this and is it a problem? Pictures from both sides:

That's the Wix bypass valve. No problem, it's sandwiched in there pretty good. That's what you hear folks on here refer to as a "base end bypass"

cut it open

Yep, looks like the gasket on the base end bypass valve. Looks to be shifted somewhat out of place or deformed, but you would have to compare it to a new filter.

As noted, that is the gasket portion of an Wix/NapaGold thread end bypass piece. More than likely, just a bit extra of the gasket extended outside the inner portion more on one side. In my experience with the 7356, the "warp" as you refer to it, or wave(s) in the visible rubber gasket is not uncommon to see on the piece. I've used many 7356 in past, seen it (gasket wave), and it's never been an issue in use.

As with many topics, this one has been discussed before and bypass gasket wave can be seen in link with pic.

Is this normal? Wix 57356

Hello, Just bought a Wix 57356 filter today and it looks different from the other filters I have used (NAPA Silver, NAPA Platinum), specifically the piece of rubber highlighted in the attached picture. It looks like this filter has the up-front bypass valve, I believe. Is that correct? The...

It is not the WIX made Napa Gold but the Mann Hummel made version....

it's clearly a Wix, given the baseplate design and the coil spring bypass. There are many examples of these on BITOG, including this one. If it was a Purolator, it would look like this.

What is the date code on top of yours?

While Mann has owned Wix for awhile, they only recently started switching some Wixes to the inferior Purolator design.

Look at the 1st picture it says Mann Hummel upside down just below the gasket. All my Napa Gold oil filters have been Mann Hummel for about 2 years now. I kept my last Wix marked filters to compare.

That is because Mann owns Wix, but they didn't change the design immediately after taking them over. Even though Mann bought out Wix, they initially kept using the same Wix design, same coil spring bypass, same baseplates, etc.

The consolidation to the Purtolator design happened more recently, mostly during the pandemic.

Compare the filter this thread is about to the Wix-marked filters you have. They will be the same.

It's what's inside that counts, and that's why you should cut them open

Wix labeled, Napa Gold same filters. For some time now Wix labled filters have also put the Mann Hummel name on the label. What you have though is an Original OG Wix/Napa Gold oil filter with the traditional Wix thread end bypass piece. While these are likely to go to dome bypass and be more like Purolator in furture, irrelevant here because that's not what you have.

The Wix plant in Gastonia NC does have the Mann&Hummel name on a plant sign, it also retains the Wix sign too. I know this because I've driven by the plant several times on the way to and from the ATL.

Edit: Just read the comment where you said "I'll cut them open and post my findings". I hope for the topic filter at least, and any other with thread end bypass, that will be after you use them. Otherwise imo, a waste of a perfectly good oil filter. Linked is the last Napa Gold 7356 I ran and did a c&p. No reason to think topic filter would be different.

Napa Gold 7356 Cut Open

This one run 4900 mi, one year with Magnatec 0w20 on 3.5L Honda. Super Tech Synthetic 10K mi (from box) and Bosch Prem. 3323 went back. First time using box oil, found with 12qt box best to have a saved 5qt jug to work with, which I did. This might be first louvered 7356 I've used, they were...
