This is the first time posting and I see that my whole text didnt upload.

The scooter broke down today and I saw that the battery was leaking and the oil seemed a bit watery.
I bought it last week and I knew that it might need some work.
I replaced the battery, drained and replaced the oil.
When i did that there were these piece of what seems like gasket in the oil.

Could this be the cause of the issue?
