True, but (yeah, your infamous, yeah but), it seems to be prevalent with certain models of MC and Purolator filters and (for me) it matters not when it happens--either in manufacturing or in operation, it only matters that it does and is happening. Far too many other brands on the market to buy a filter that has known issues.
If this were the first time seeing it and I made that comment then yes agree it would be a presumption. But we have at least 5 years of similar posts with similar visual proof in this forum. Pics of used filters with a tear in the paper media right where it glues to a rigid metal end cap. None (that I'm aware of) that show virgin filters like that. None (that I'm aware of) that show a used cardboard end cap Orange COD or TG failing like that. Its the presumption that paper end caps are bad and metal end caps are good that I think is false.
I'm not convinced of anything other than there's clearly an issue afoot, and has been for a while. Seemed that it was constrained to only some filters, but now it seems it may be creeping outward.
The engineer in me wants to know the root cause.
The consumer in me says "results are what matters most" and so this probably will put me off MC filters until some evidence comes forward that the issue is resolved.
The Fram EG (aka Orange Can of Delight) is looking better every day, now that they include silicone ADBV.
The big MC tearing problems seem much more common on filters that have metal seam crimps (although glued ones have failed on occasion as well). Until we find a way to cut new ones open, weld them back together, use them, and cut them open again we'll never know for sure!
BUT-when better alternatives are available for not much more money (M1, Ultra, RP, even Fram Tough Guard & Extra Guards), it seems kind of dumb to risk it. Like the Johnson Controls batteries listed above-when you've personally had a couple of them fail, one with potentially deadly results from rust & corrosion, why use inferior products at all??
