An oil leak that collects a thick layer of oily dirt normally is not worth fixing. Just wash down the engine once in a while. When the leak washes the dirt off or leaves puddles underneath, that's the time to fix it.
I would never use a pressure washer in an engine compartment. The high pressure can blast water past seals. I spray it down with Gunk or some other degreaser. Let it soak in, then hose it off.
