2002 Turbo diesel Prado - Problems and Questions

Ok, I won't bother with the story for now, but my sister's Prado basically overheated and warped/cracked the head. Car is obviously ~3 years old, but only has ~67000km's on it. Well short of the 100,000km warranty, but was about ~3 months out of the 3 years part. Car is constantly maintained.
Now I have some questions:
1. Does anyone know if it's an inherent fault?
2. If so, was it caused by a faulty casting of the cylinder casing? (Was hinted at by a toyota employee, that when questioned by other staff then declined he said it, and basically asked what a cylinder casting was just after he had said it).
These are the important questions as Toyota are keeping mysteriously quiet on what the real cause is.
3. Anyone else have it happen to them, or know of anyone else that did?
4. Just a thought, since my sister lives in cairns, would it have possibly been something as simple as over time the car couldn't handle the constant hot environment?
5. Would an accidental overboost of the turbo cause the fault? Could the turbo be a contribution or a fault?
Does anyone know what the engine model code for it is, and if it was a 1st gen engine, or a revised version? Thanks.

Engine is 1KZ-TE. Had one in my Hilux Surf, circa 1993 very first year of production. They change the throttle setup in the very late 90's but don't know of any major casting changes. There were drama's with the idler gears for the injector pump and I did blow my Turbo($900).....just once.
I have heard of head problems with these, namely cracked head due to overheating but why I don't know. Mine was a manual hence no transmission cooler in radiator, maybe manual's are less prone to over-heat. I did put my engine to the heat test in the peak of Summer here, meaning 40 degrees. I basically drove down my local beach with my tyres at full pressure still(meaning 40-50kmh is flat strap ) in the very soft sand that we have.
The alloy head handled the high load and high temps just fine for the 40 odd Kilometres to the next small town. The Viscous fan was running locked constantly and the little thermo was cutting in out now and then. I had the air-con on too with windows down:)
Temp gauge just barely moved.
