Spectacular breakdown - trashed Turbo?
Wanderer:
I'd be more inclined to the head gasket going causing it to run on it's own oil.
I can't see where all the water would be involved with a turbo having gone. It's a coming together of oil, water and fuel (engine oil).
It does happen. Not too common but it does happen.

It overheated due to the overrunning and I guess the coolant just boiled over. It was escaping through the expansion tank cap.
I started stripping the engine back today. So far I've removed the manifolds and turbo and with the exception of the cylinder head bolts I'm ready to take the head off. I can't tell if the turbo is dead or not just by looking at it. Anyone know how I can test it. It looks pretty old though so since it is one of the main suspects in this problem I guess I should replace it.
This is turning into one of those "While I have that off" things. While I've drained the coolant and have all the auxillary belts off, I think I'll change the timing belt. Anyone know where I can get a viscous fan spanner?

Well, while you've got that off... might as well put an electric one on there :-)
Have a feel of the little fan in the turbo. See how much lateral movement there is in it. Does it turn freely, etc.

No lateral movement. Turns freely when moved around with my finger but stops immediately when I stop pushing. I can't spin it. The again, perhaps it's not meant to. The blades are covered in engine oil. I haven't separated it from the exhaust manifold yet as I understand this requires a new gasket on refitting so I don't know what it's like on the inside yet.
Wanderer:
I've got a viscous fan spanner here if you can't get one.
You're welcome to borrow it.
