Could be the fuel pressure regulator and injector/s leaking and finding its way to the crankcase.

I don't Know your motor but this normally happens to engines with mechanical fuel pumps, the diaphram has a pin hole or rupture allowing the gas to pass thru and mix with oil. When it gets realy bad the pump stops working and the vehicle won't start
