Looks like I’m dripping oil onto the exhaust, can see it through the passenger side wheel well.

Valve cover gasket, or could there be another culprit on an ‘09 5.4?

The leaky valve cover gasket may be the symptom. But the actual cause might be a clogged up PCV system as well. If you take the oil cap off with the engine running do you feel air pressure trying to get out ? Cleaning the PCV system involves removing the driver's side valve cover and accessing the PCV passages to clear out the crud so it can breath again.
Or just replacing the driver's side valve cover.

Mine was a cracked valve cover gasket on the passenger side. Do the intake gaskets at the same time, rubber is getting old.
