Not a good sample

I noticed a month ago that my Amsoil EAA189 was letting a lot of dust around it. So I put a Napa Gold air filter in but as you can see by the report my sample was bad. I wanted to know if this means there was some damage to my engine or will it be fine now that I put new oil in. My plan is to run the Delo LE I put in for 5,000 miles and then change it again to see if anything changed.

MAKE/MODEL: Cummins 6 BT 5.9L
FUEL TYPE: Diesel
ADDITIONAL INFO: 2004.5
OIL TYPE & GRADE: Schaeffer Sup 9000 5W/40
OIL USE INTERVAL: 15,000 Miles

BRADLEY: A lot of excess wear, silicon, and soot turned up in this sample. Universal averages show typical wear levels after about 6,800 miles oil use. Your oil was run a lot longer, so we expected to see some higher wear, though mainly at iron. The other metals should stay closer to average, even after a longer oil run. Silicon may be a cause of the high wear if it's from dirt, so check the air filtration system and resample in just ~10,000 miles to monitor. Soot caused the high viscosity. The TBN was okay at 4.9, so you didn't run out of active additive. 1.0 is too low.

That is a lot of iron! TBN of 4.9 after 15,000 miles is impressive.

Just a tick under 7ppm Fe/1k miles is nothing to be afraid of if you correct the issue at hand which I think you may have. Trust me there is worse that can happen to an engine.
 
VERY high dirt ingression. I doubt it is through the filter, probably a bad seal, loose connection, or somewhere else. Check all the connections, tubes, etc.
