aluminum high in oil sample

[pops250]

Just had an oil sample done by Blackstone and it came back with aluminum at 33 up from 12 4000 miles ago. Since the last sample I had egr and dpf deleted, also just had rear main seal replaced at dealer. I was wondering if any of these could be the reason for the count going up so. Their report said usually would come from piston scuff. There was no coolant in the oil and fuel dilution was less than 0.5%. They said everything was fine except aluminum was a little high. Any ideas. And also if it is piston scuff what causes that and is it anything to worry about. Truck is an 08 f-250 with 54000 miles with no real major issues so far. (knock on wood)

My oil analysis also said I had high aluminum numbers in my oil. I also had a small amount of coolant in the oil (0.08%) Turned out the front cover was being cavitated and the coolant was slowly leaking into the oil. I know you don't have coolant in your oil but the front cover on the water pump is made out of aluminum .... just something to keep in mind, especially if you start loosing coolant or seeing it in your oil. Good luck.

My last Blackstone seems to be exactly the same as Hunters. I talked to the dealership and they said they should be able to do it under warranty, but would need my truck for a few days to diagnose that it is because of the old front cover design. I'll be dropping it off on Monday. I'll keep y'all updated.
