Transit died- are these symptoms a blown turbo?

[Aprisa]

Hi
Our transit went U/S last week and I suspect the turbo, the symptoms are:- complete loss of power on the motorway whilst going up a long hill, oil blown out of the breathers over engine and oil thrown down and out of the exhaust. Once cooled the engine starts and runs fine and sounds good. The problem then repeated itself after driving another three miles.

Any other opinions before I lay out for a new turbo?
thanks Nick

Thanks so far, the reason I thought it was the turbo rather than other forms of engine failure is that when cool the engine is sweet as a nut, I thought if the turbo had seized when hot then the back pressure of not being able to allow gasses down the exhaust would pressurise the crankcase and also give the complete loss of power and stalling when clutch depressed.

Am I way off?
