Hi Darren,
It's a common assumption that the thermostat housing splits. It doesn't. The leak comes from the flattened 'O' ring at the housing base. The resulting spray of coolant coats the housing seam and accordingly misleads people.
It also isn't likely every two or three years if you follow RAVE's instructions (hard to interpret I admit) when assembling the coolant parts in the 'V'.

The upper limit is even worse than you warn Darren; it's 115°! This phenomenon is nothing to do with MG Rover. All marques do it now. It persuades the non technically minded motorist that huge technological advances have been made.
