The first thing that comes to mind in these cases is that the problem is a burnt head gasket that has allowed liquids to pass through, but this is not the issue: the problem was caused by a faulty water pump, which had a broken gasket and contaminated the oil in the cap that is in direct contact. The car was overheating, and the hot air was not flowing.
