Ya seems normal
Technician: Nich1019, Cummins/Caterpillar Technician replied 1 year ago
More than likely the oil consumption is due to piston rings and liner wear. In some cases you'll have oil consumption from valve guides and/valve guide seals, but it isn't common in this engine.

I've owned the truck from new and had several motors done just seems odd the way it's using oil and where is it going
Technician: Nich1019, Cummins/Caterpillar Technician replied 1 year ago
I would have a repair shop perform a blowby test to see how much blowby you actually have. You could also perform a compression test and that may indicate ring and liner wear.They only other thing that I can think of is a turbo pushing oil. You can inspect the piping from the turbochargers, both inlet and outlet to check for oil.

Have checked all the pipingThis truck is turned up to 650 hp bust has been for a few years still makes 54 lbs of boost I have trucks with the acert mxs engine the same vva delete and same horse power running 45 lbs of boost and run fine
Technician: Nich1019, Cummins/Caterpillar Technician replied 1 year ago
Ok in that case I'd perform a blowby test and see how much blowby there is. I'm pretty sure your issue will be the rings and lo
Iiners. Also check your air intake piping from the filters to the turbo inlet. Check for signs of dirt intrusion from leaks in the system.
