106 xr can you help

I bought a friends vehicle 1 month ago, 20 thousand km ago, 0 engines were made. Today I went 50km with the vehicle, I used it at a high speed, there was a slight odor, when I got off, I saw something like oil incontinence, I don't understand much.

There is no problem with oil vapor drainage teacher. Since you force the vehicle too much, a small amount of oil has come out.
