Between ROM and OXI layers

As a follow up to my first post – we just opened up the SCR that has 5700 hours on it for the first time and we found a lot of debris in the later sections of the SCR.  I’ve attached a picture of the section between the ROM and OXI layers.

Based on the soot we see in the HUG sample filters, we were expecting excessive soot build up in the SCR to be causing the degraded performance, but we were very surprised when we saw very little soot.  Is this similar to what other users find during their inspections?  Have other users found the expansion mats to break free?

Thanks,

Mike
