Oil in the coolant of a Cummins ISX engine can be caused by several issues, primarily a blown head gasket, which allows oil to mix with coolant. Other potential causes include a cracked engine block or cylinder head, or a failed oil cooler. These problems can lead to significant engine damage if not addressed promptly, as they disrupt the engine's cooling system and can affect overall performance. Regular maintenance and monitoring can help prevent these issues.

Broken head gasket...since an ISX with 200 miles is still under warranty, let Cummins fix it.
That would actually be dependent on the make and model of the truck, not the engine. Even if it was dependent on the engine, you never specified if it was the ISX12 or ISX15.
