I gave the care a thorough talking to before more checking this morning... but it didn't seem to help.
Antifreeze covering one of the plugs. Head gasket must be gone. Seems awfully strange for a Zetec w/ 62k miles on it and not pushed too hard...
Anyway, I think I might be able to fix it myself... I've replaced an intake manifold before, this is just basically the next step, right?
One thing I'm not sure of is how likely is it that the head is warped or cracked?
