Anyone know for certain if the D4D turbo is water cooled? I'd read somewhere (might have been in a cool down after driving thread) that they were but I can't see any coolant pipes to or from the turbo.

The problem with oil cooling, is the oil need to be at low pressure, so it doesn't blow past the seals and into the turbine, and unfortunately with the low pressure you get slow flow. This means the oil can't take enough heat away, and you don't get much convection after the engine stops and it cooks the oil, damaging the bearings.
