Did you change your fuel pump??
because if you had trouble installing the fuel pump.. and i am hoping you used a new one.. it could be leaking internally.. filling the oil pan with almost gravity feed from the fuel tank..
How could thid happen?? ok, the feul pump has 2 valves inside and one spring loaded diaphragm, So when the diaphragm is pulled up.. the fuel is pulled thru the inlet check valve filling the cavity.. as the diaphragm is released spring pressure pushes down with enough force to create about 5 pounds of fuel pressure. this pushes fuel thru the output check valve.
That's why if the diaphragm is damaged during install.. the fuel can leak into the engine under some conditions.. there is a vent hole on the side of the pump to prevent this.. but it can happen..

Maybe i make it more complicated for you, but it's just to show you how could a damaged fuel pump can cause your problem.

Best Regards

Oui, c'est a quelle niveau que tu t’aperçois du mélange?
Une segmentation Hs ou un injecteur qui pisse peu rincer l'huile aussi.
