And if, if one did make to the engine side the only "meat grinder" would be the oil pump and it has a screen on the pickup tube to prevent any debris from entering the oil system. Any photos from the ordeal?
Initially my thoughts too BUT if the ring were cut and had an end dangling and inside of the filter I could see it getting to the pump and since it's already past the screen this is, however unlikely, plausible, barely. One would almost have to deliberately place it there.
I am nervous every time I tighten one of those canisters as it always feels like the O-ring is dragging and stretching. Just as it snugs up I always back it off a bit and re-tighten, it feels better after relieving the tension. Maybe it's my imagination.
Interestingly enough our OP's first post here was regarding Nikasil engines. Yeah, I'm skeptical too.
EDIT, again: using my sometime rudimentary reading skills I see the O-rings of the inner sleeve, the dildo, are the suspects. I can see that happening. Perhaps not assembled incorrectly as speculated but just old and failed when inserting. Aftermarket filters don't always come with all the seal rings so lots of them in service are very old.
