Oil- Blow/By- Leak

[Nw_adventure]

So I am looking around the air filter box on my Ecoboost and I noticed quite a mess of caked on oil, sludge, some drippings and a overall not so awesome scene just to the left under the factory airbox- Some valve with a orange triangle seems to be a fill/relief valve of sorts and there is just oil and grime all over- At 17k miles this is not great but hoping its just a defective valve

that needs to be replaced. Any ideas ?

Transmission vent. Perhaps overfilled a little at the factory and venting when hot?

Definitely seems like that - I cleaned everything off and will monitor.
