2014 Ford V-10 Dropped plastic cap down oil fill tube

I would think the filler tube routes directly to the oil pan reservoir.
The oil pump should have a pre-screen before supplying oil through the oil filter and then to the engine ports.

Running the motor shouldn't be a problem. It's not like the old motors with the sump/splash pickup.
Now, I'm showing my age...LOL.

If it's not stuck in the oil filler tube, just drain the oil and remove the oil pan to retrieve it.

Not a fun job, but very doable.
