Did the 5.4's have the same head gasket problem the 4.6's did in '99?
If it were a 4.6, I would say head gasket for sure...

Standing oil in the valley can easily be oil that did not make it into the fill tube when oil was added or changed.
The valley really does not drain so....
You would have to clean it really well and water will evaporate. Then you can monitor, if it does indeed leak, where it may be coming from. Some candidates would be valve covers, pvc grommet, pvc hose, oil fill tube gasket (o-ring), intake, etc.....
Word of warning: Take great care not to get water near the cops (may be impossible), or plan to remove them and blow compressed air down the plug wells and make sure they are completely dry before re-installed.
