Hi Farmerdave - That actually makes a lot of sense but you would think that ford would have some type of plug for the unuesed rear coolant passages. The reason that I have to change my intake manifold is that I was getting anti-freeze into my number 7 & 8 cylinders and based on my compression testing, it does not appear to be a head gasket problem. I am sure the coolant is under some pressure when it comes up the rear coolant passages and hits the intake "wall". This pressuse must eventually cause the gasket to fail. I might have this all wrong but hat is what I am envisioning.
