It's either that or you added oil to the engine, in the process spilled a copious amount around the neck and it went under the beauty cover and found it's way to there....
Not "overfill" but spill.
However you state it's clean under the beauty cover. Has to be a VC gasket.
Besides over filling (as long as 1L or less) would not do such.
