Hi, my name is ***** ***** will be assisting you.

Yes, there is something creating and internal crankcase pressure that is causing oil to be pushed out of the fuel pump. The first place that I would look at is the head gasket. I have seen a lot of these head gasket partially blow and the engine still seem to run okay but it will start using oil, whether it is burning it or pushing it out through other places.
