100% this is coolant and it is leaking as the pressure builds under hard acceleration onto your hot intake and the cloud is carried out the back by airflow. It happened on my LR4 I suspected the same PCV Valve, Leaky seals but when the water pump and coolant pipes finally let go and were replaced this issue also went away. I would bet you have an old style (original) water pump with the weak lines. It will fail and you will need a new pump and fixed lines. Get it done now to avoid a future tow!
