Any advice on what could be

Answer
If your Rover is building cooling system pressure from inside the engine, $2,000 is not going to fix it unless the problem is limited to head gasket failure.  If you have short block liner trouble, you are probably looking at $7-10,000 for a proper repair.  

Here are links to two articles I've written that describe the situation in more detail.  OUr company is known for repairing these issues, but it is very costly.  At least 80% of the overheat failures we see nowadays are liner failures; the more expensive problem.

Expensive as this is, we do lots of these repairs because people love the cars.
