Cat 308 Oil consumption problem

[Dieselfixer]

Hi All, Looking for some thoughts on this problem I'm having with a 2007 Cat 308C CR with a KCX serial number.The problem is oil consumption of 2- 3 quarts per day. No leaks and no smoke, no oil showing up in the cooling system, Have no idea where the oil is going. Possible for it to be going into the fuel? Any ideas would be helpful.
Thanks.

Replace air filter, see if oil consumption changes.

Turbo?

Pulled engine and upon disassembly found a broken piston ring on number 2. Rebuilt and running fine now.
