All had between 5-6K using mobile 1 5-30. All three looked just fine. No tears and all parts in place. Sorry no pics but nothing to see. I plane to try some of the Frame extended guards and will cut them open as well. At this point if I ever find a pure-one (my filter of choice) torn on the seven vehicles I service I will post pics.
Cut open 3 Pure-one filter

I had three failed purolator filters before I stopped using them. Not sure what their is to wonder about.

That's interesting. Why do you have so many failures when others never do, like the OP.

It would be interesting to know more of OP's application beyond the information given, and what part number & serial number Purolator he used.

That's my point.I have wondered if some engines have too high OP or if too thick oil is being used that may damage the filter on cold start. Just askin. Madia damage seems weird to me under normal conditions.

I am the biggest fan of Purolators out there and have used them after joining this forum. My last one that I ran on my Caddy (a classic for 9k miles) came off torn. I'm running a P1 now and if it comes off torn I'll have to reconsider my allegiance.
The filters I cut open last week were two PL14612 one from 07 WRX and one from 08 350Z and a PL-25288 from 03 cad Deville.
I have been using these pure1 filters for a while but never knew about the tearing issues. So for now until I find a torn one I will keep using them, however if I find tears I will switch to something else like Toyo Roki in the Japanese cars and Fram ultra in the US cars. One thing I did notice is the Fram version is about 1/2" shorter than the PL-14612. Also looking at the Pure1 guts I can see why some reports of media packed too tight could lead to more bypassing or could lead to tears? The pleats are pretty tight. I don't think I will keep using them on the 502 that takes 10w30. However it does have one on it now so I will cut it open when it's time. Also I find the Muffler tubing cutter from Harbor Freight (4 wheel) cost less than $15 and works very well. One last thought, could the tears just be pleats too tight then the high efficiency starts to restrict the flow and the media is just not quite strong enough and tears before the BP can open. If that's the reason I would hope the fix it tougher media and not weaker BP spring!.

Ok one more last thought really LOL. The pure1 is suppose to be changed every 3K. I go 5-6K, with people using synthetic oil and running a lot longer is the high efficiency media getting restricted? Are there reports of the pure1 for synthetic oil with a lot longer run time tearing? I will probably try them if I find any regular Pure1 tears. Since I run synthetic 5-6 K will I ever see tears, that's the real question for me to determine.

How many others cut open every filter?
The failed units came off from My 2010 F150 that I owned since new. I used synthetic oil and changed it every 7K miles. The truck saw 95% highway miles so it was easy on oil. Technically I had one manufacturing failure and two media failures. I think I still have one Ford racing filter left in the stash. So far I have not seen anything wrong with the Ford filters, but from now on it will be Wix for my Jeep.

There is always something to see. With or without tears.

Pure 1s are good for 10k if you want to use them
The Motorcraft racing filter has better efficiency, roughly 50% more media, better flow rates, and a thicker can when compared to the regular Motorcraft filter. Also why would I want to put a Pureone on my vehicle when they have demonstrated that they have poor quality?

The two PL14612 had the pleat ends secured with metal crimp strip and the bypass in the bottom (not the threaded end). And the PL-25288 from 03 cad Deville had the pleat ends glued with no metal crimp and I do not see any bypass valve, is that maybe due to it being in the engine? It sure wasn't in the bottom like the other two?
^^^^^^Everything you describe would be normal and as designed. 03Cad as you suspect has an engine block bypass, so none is spec'd for the filter. Be that way across all filter manufacturers.
As for describing bypass location, dome end (as opposed to thread end) is perhaps a better description than bottom as depending on filter orientation can be vague. But I knew what you meant. All Puro labeled filters use dome end bypass where one is spec'd.
Good to read of your positive anecdotal experiences with the P1.

I've posted probably 3 or 4 Purolator filter dissections here in the last year or two, none of which have been torn, none of which have had wavy media, etc. I do think there are likely differences specific to the engine on which the filter is used.
Here's one of my P1s
And here's one of my Classics

Thats something to write about !!! What are the chances of getting 3 purolators and not see any tears?
But if you think about it and people are posting when they get good ones and sometimes three in a row...YEAH!
Why would anyone think of taking a chance with them on something so expensive like an engine.
By the way i cut 2 open yesterday from engines here for rebuilds and both looked good, no tears but the media was a little wavvvy.
