This is a common issue on 2000s Ford modular engines because the geniuses at Ford decided to include about 1 inch of plastic in the pathway of the coolant crossover pipe. Eventually the hot coolant traveling between the iron engine, plastic, and aluminum of the pipe causes the gasket to fail leading to catastrophic coolant loss. The PI intake manifold corrects this problem by only using aluminum in the coolant crossover pipe so obviously Ford knows how to do it the right way.
