Hi All,
Here is what I found with my 2002 4.6L intake manifold after 199k miles. It had been losing coolant for a few years, but after it got really bad I finally put a new Dorman intake on it. Here are the pictures of what I found. I removed the coolant runner off the front to show the blown seals and the plastic and foam insulation ( I guess that is what it is) had completely deteriorated and fallen off the manifold. The manifold swap was not that difficult, it just took a bit of time and no fancy tools. The strange part was that there was no obvious leak.. I guess it was just steaming out. There was never any antifreeze leaking that you would see.
If you have a mystery coolant loss this may be your issue. I was afraid it was a head gasket. By the way the Dorman replacement does not come with this insulation stuff and uses O-rings to seal the manifold instead of the gaskets that Ford uses. Very nice improvement.
