I also have the dreaded head gasket leak/ weeping and oil collecting in the galley of my '04. There is a TSB on this you can get from Ford or someone here may have it. It says that the leak is not detrimental to the durability or performance of the motor,,unless of course it completely ruptures then it well need to be replaced. I'm just living with the leak at 95k and it migrates everywhere. It just kills me to think of replacing both gaskets and then a valve job and then maybe you will need to replace the heads. Just live with it is my suggestion. Let me know what you figure out. Thanks. Phil in Santa Ynez, Ca.
