1979 8V71 water leak out of turbo jacket?

[Dallastx75208]

What are possible reasons for water leaking out of turbo jacket. No water is getting into the engine or steam blowing out the back exhaust.

Hi,
I'm not familiar with the term."turbo jacket" so I could be way off.

But my first guess would be a bad aftercooler.

Anything other than air and oil coming from the blower box drains?
