Found mainly non ferrous motor in oil on change? Truck has 215k but was running perfect, 2 months ago had head studs , oil cooler egr delete, edge evolution tuner, blue spring, ficm, and coolant filer by mishimoto Polly can't remember off the top of my head without going through receipts. Just wanting advice on next step(currently have turbo off and stripped all the way to the valley), should I pull valve covers and or heads ? Gonna pull ipr and ipc tomorrow, just got the sockets in. Anyone had this happen or seen it? Thanks everyone just really need some help and already shelled out 15000 grand in last year on the truck.
