2021 3500 First Oil Analysis

Iron is going to be piston rings and/or cylinder bore material, not valve train.

I would re-run a sample ASAP because those iron numbers would have me concerned. I'd send part of my next sample back to the same company and another part of the next sample to a different company like Blackstone or someone else.

I have a hard time believing a new motor like that is already producing blow by so I'd want a second opinion on my next sample.

Why do you think valve train wear wouldn't cause higher iron levels? The pushrods and valves are steel are they not? It could also def be the rings or cylinder bore, but just curious why you rule out the valve train?

Vanadium and chromium are usually elevated when contact wear parts are shedding or becoming compromised indicating elevated coating wear (bearings, valves, push rods). Chromium is more specific to steel alloys and in my opinion would be indicative of pushrod tips and/or lifter wear.

Iron is almost always rings or cylinder walls and is usually expected when a motor is brand new and the new mating surfaces are bedding together.
