I am new to the forum so please excuse my ignorance. It seems several members who I assume are doing their own repairs are taking the time to cut open the oil filter during an oil change. Can you enlighten me (I am being serious and sincere) as to the reason for doing so? Also, are there any techs currently in the trade doing this. Thank you for taking the time to answer my question.
Cutting open oil filter...?

Looking for flaws. And we get bored.
Bragging rights.
Welcome. Today I was in Santa Rosa at the Safari West preserve. It was a really fun tour!!!
I was a tech for Chevrolet in the 1980's and I cut open a few oil filters when instructed to by Chevrolet. I believe it was to check for metal shavings when performing warranty work.

lol, yeah this was a new one for me too. I kept seeing all these post about filters and would open one up and see all these pics of cut open oil filters and thought to my self w.t.f! Of course now, I have done my own filter cutting and have been looking for another one to inspect, great forum and tons of info for the diy guy!

And neither would Purolator..

I cut open oil filters to see how they held up under usage in the vehicles I maintain. I look for stressed pleats, tears, amount of pleats, construction, etc. and I use my analysis to help me choose which filters to continue using and which not to use.

There you go. I have been accused of practicing compulsive, neurotic car maintenance for years. But, I have never cut open an oil filter. For some reason I don't even care if it has a huge hole inside. It's not one of those things keeping me awake at night.
But, I still do enjoy checking it out when others do it.

Initially, it was curiosity. I cut one open with a hack saw to check the media on a Mobil-1. Obviously, after using a hacksaw, checking for metal shavings is not really an option...
I wonder whether shavings are really observable unless an engine is really in bad shape.
I also think it is a way to keep filter manufacturers honest, and hold their feet to the fire, as they do on this site.
I should add that I have since invested in a filter cutter (Proform 66490 Oil Filter Cutter). Haven't yet used it.

Oil filter changes are maintenance, not repairs. Maintenance can be anticipated and scheduled based on mileage and/or the calender. Repairs are generally not anticipated until actually needed.
The reason I cut open filters is primarily to assess the condition of my engine oil, and by relation, my engine. If there is sludge, debris, water, or metal shavings present, I have learned something. If there is a trend towards more filter loading, I have learned something.
If everything looks OK then I know certain aspects of my engine are still in good shape.
Actual filter failure is relatively rare. While I always look for it in a cut filter, I don't expect to find it. I found my first one just recently.
