I was put a lot pressure on the media base to see if it tear . It’s not . I end up put a lot more pressure on the base of the filter where it glue to the metal base and it finally separate . The glue is separate from the metal base . But the filter still attach to the glue . The glue look like green color .What's up with that? Shouldn't be able to make the potting open up like that with some pleat side pressure. That's something not ever seen before it seems.
Yes, another issue is end cap bonding, many end caps have been seen popped off on Purolator made, end cap poppers. So if you press hard like that and the glue is just resting on the end cap, not bonded, it is going to open up a hole. Thankfully the center tube is the structural element. Wonder when we will see more filter tests by the member here. You can also see the virtual impossibility of the adbv to go over the neck of the inner side baseplate, even if the guts get a little loose. Which hasn’t been shown to happen on these.
I've handled Purolator made filters that have popped off the metal end caps, and the potting material if very stiff and can't be deformed like in MetalSlug's photo. Just seems strange that a big gap between the potting material and end cap could be opened up by pushing the pleat over. Now I'm wondering if oil pushes a pleat over even slightly that an oil leak path can open up at the end cap - ??.Yes, another issue is end cap bonding, many end caps have been seen popped off on Purolator made, end cap poppers.

The old metallic blue Pure One (usually with the string around the media) was the best non-Boss/Synthetic Purolator made. There were a few sandy gold ones posted here that did tear, unfortunately.Oh man I miss that gold dust pure one . It’s was BITOG all time favore
