Good day folks. Filter and Safety Kleen 5w30 synthetic oil off of a Mazda CX-90 SUV with inline 6 cylinder. 7,500 oci
Typical Purolator slacking quality: endcap fell right off as I went to pull element out of can. After I took photos; went to toss out filter and other endcap fell off. Shoddy glue job and shoddy filter 💀☠️

In/on: same oil and filter.

Looked great to me....................
The caps dropping off out of the can only mean it's easier to spread the media out once cut.
Means Purolator: JUNK! Sad that I cut a PZ filter open last night with end crimp looking like Purolator and China style baseplate; had no tears and endcaps on solid.
 
Is there a functional effect of the caps coming off after being cut open? Aren't they forced to stay in place during operation?

When the life of my motor depends on the ultimate filtration I only reach for Purolator ...
 
Helping the Quality Assurance Dept. out at a few MFG locations over the decades I know how this happens.

Spec notes on the part or mat'l print calls for clean parts, one of three suppliers sends in a lot of stamped mild steel parts with RP342 or similar anti-oxidant coating on it.
The Incoming inspector flags and moves the incoming lot to the Material Resource Board quarantine storage for Mgmt. Team evaluation and supplier followup. The is no chem cleanline in our mfg facility. It's costly and a pain dealing with EPA tsca and sara.

Second shift Mfg Manager comes in, needs the parts to meet quota, some flunky supervisor says "they look good to me" and they get used. We go to do a MRB later in the week and ... no part! Then the finger pointing begins.

Why cardboard end caps - or no end caps can be better.
 
They are not designed to be taken apart. Likely meets ISO spec.

And if it a tad leaky - as with the ruffles on FRAM, Most of the oil is going through the filter media constantly at high volume, the oil pumped from the sump is clean - unless you are silly and doing a parking lot autocross engine expiration session and stirring up dregs.

Remember that Any filter with a dome-end bypass is dumping accumulated garbage into your engine periodically. So what then?

It's a Fail Safe that is not so safe

So, clean (not broken apart) endcap popper shown which according to member Jim Allen's reasoning when phenomena first seen, means no oil bypass in use with compression spring intact. That being the case here, beyond the aesthetics of it with c&p, looks to have gotten the job done at 7500 miles. Not bad for a jobber filter, imo

Thanks for c&p.

Yes, and least no tears finally.
 
Yes, always a good thing with M&H Puro made. In my observation, beyond the endcap popper results very similar to your other recent US made Protec at 8k miles. No idea what they cost, but what I've seen generally, decent to my eye.
Supposedly they are in the $3.85 range which is 76 cents cheaper than champ labs. I would love to have champ labs back.
