How to address valve cover area leaks

There's a ton of grime on the port side coils as well around the oil fill riser. Is it safe to pressure wash these areas? What kind of work is needed to stop the leaks? Is the oil filler riser grime just bad aim?

That looks like bad oil filing job to me.
Anyway, I never hesitated to wash my engines with water and only old Fiats come with occasional misfire when I got the plugs wet.
That would dry out and stop.
Still not recommended to spray water on coils and electronic modules.
I would buy "Engine bright" stuff and spray the gunk before washing with water.
For semi-solid stuff you can pick wood spatulas at Home Depot. They give paint mixing sticks for free.
