OP, just for clarification, is that an actual Insane Diesel filter, or a filter from another company? I am assuming it is the one that came with the kit given your posted mileages. I ask though because the pictures on the ID website show a gold ring at the top of their Extreme 1 filter, but there is not one on yours. Of course our trucks take the Extreme 2 filters, but the photo on their website of that filter doesn't show a shot from the top so not sure if looks the same as the same as the Extreme 1. But if so, did it look like there were any possible issues with it when new?
Was that the top side of the filter, or the bottom side, or both? Have you looked inside the canister to see if there are any rough surfaces on the bottom or the underside of the lid that could have lead to this? I assume the lid was installed and seated fully, securing the filter in place?
Also, do you run any kind of additives that could have lead to this?
I ask because I was planing on ordering one of their kits for my truck once Black Friday came around. I haven't seen a lot of reviews on these filters, however, the ones I have seen have all been great. This is the first one I have seen like this.
Also, given that others used actual toilet paper rolls for this in the Frantz system, it makes me wonder if that shredding is truly even a concern. I have no idea, but I wonder if pieces of the TP shredded off like this in those systems too...?
And if I am looking at the schematic correctly, when looking at the oil flow, it doesn't look like these pieces can actually escape from the filter housing and make it's way into the rest of the oil system because the oil flows through the filter back into the system. Those pieces would be way too large to get through a 1 micron filter.
Thanks!
