OG Fram Titanium FS7317 C&P with bypass flashlight test
- Thread starter GW.

Nice! Comparing the topic bypass piece seal area ring in pics #4&5 (from top), to the Champ Labs made FE 7317 I posted, it's easily seen how much wider and smoother the finish is in the areas 90° to the stamped spring arms. Not surprised at your results. And you can't beat the media either.
Thanks for c&p with the light application.

I’d say it took a fair bit of effort to pull apart. The bypass sits deeper in the end cap vs the Endurance too I believe. I’ll have a couple Endurances to test in a couple months.
Glenda W: are you wicking media and pulling it apart?
Good idea! I probably should to see if R&P is liberating some piston deposits. Oil is definitely darker than normal if that indicates anything.
I like pulling media apart as in case of bro’s 68’ Caddy oil filter to see the metal flecks it trapped.
The FE7317 also took a "fair bit" to pull apart too. IDK about any depth difference. But again, the differences in bypass seal area finish obvious. Perhaps your FE be different than mine and WCW, or.....
Nice photos and thanks for sharing. That is a sturdy looking filter you dissected.
As I mentioned in the other thread, if the leaf spring metal is formed correctly in the area where it seals on the end cap (ie, a flat and smooth surface) then it should not have any air gaps, just as you've found with this example.
Look at how nice the sealing area is formed here. The leaf spring on the Champ lab built filters seem all rough and much thinner in width too in this area.
I don't think there is any real seal on the sides of the center tube hole because those 4 large ridges that stick out will prevent the leaf spring from sealing. Those ridges make an interference fit to make the leaf spring fit tight into the center tube - but doesn't make a real seal. The only real seal area is around the top ridge (your red circle on the right).I can see two areas that seal the bypass valve leaf spring all the way around. One place deep in the end cap and the other on the top “bubble”.
I agree. Fit and finish are excellent. No movement at all at the interface as well.

Great! Thanks for posting the pics of the Titanium, looking forward to seeing the inside of the Endurances that you are running now.
As a side note, I have had lower particle counts with Endurance than with Amsoil EaO, I'm anxious to see how the Endurance looks when you're ready!!

So the Titanium is not a Champion product? Do we know who makes them? You think the poor showing of the Champion products in the other thread was just a fluke? As I mentioned I've had better particle count results with Endurance than Amsoil EaO, both Champion products.
Thanks again to @Glenda W. for all the work!!!

I’ve been thinking maybe the Ultra isn’t that bad. Especially since the last one I got has the louvers now, looks like a larger diameter tube so pleat lengths are shorter making them less likely to tear or get “wavy”.
Looking at the c&p’s here shows lots of waves and a few tears.

I'll have to look for those. Do you happen to remember if the center tube had louvers or holes?
