There is a bulletin for the P0299:

Turbo Air Charge Cooler Hoses Oil Seepage, or Blows Off on Acceleration.
The following diagnosis might be helpful if the vehicle exhibits the symptom described in the PI.
 

Condition/Concern:
Oil seepage from turbo air charge cooler hoses or hose blowing off during acceleration. Possible DTC P0299.
 

-Due to the closed PCV system on the 6.6 LLY engine, it is normal to have oil residue in the air charge cooler hoses and pipes.

-The oil will migrate to the lower areas of the air charge cooler system and may cause customer concerns of oil seepage.
This may also cause the air charge cooler hoses to blow off when turbo boost is high

Recommendation/Instructions:
- Do a visual inspection of air charge cooler connections and hoses.

- Replace air charge cooler hoses, pipes, or clamps if damaged.

- Properly clean all oil from air charge cooler pipes and hoses.

- Air charge cooler hoses and pipes are marked for proper installation. The hoses are marked with ENG, DUCT, or CAC (charge air cooler) the hoses and pipes must installed correctly. The engine side is marked ENG, the duct side (the aluminum pipe) is marked DUCT, and the charge air cooler side is marked CAC.

- Apply a very thin coat of sealer part number 97720043 to the air charge cooler hose connections.
Install hose and properly torque air charge cooler hose clamps to 8 Nm (70 lb in).

Please follow this diagnosis process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed. If these steps do not resolve the condition.
