Ross is on target as always. Think of it this way; with the engine running the cooling system pressure of perhaps 14 psi at most is overwhelmed by the combustion pressure which is many times greater so the heat of combustion and it's byproducts enter the cooling system. When the engine is static, the reverse may be true.
