Good afternoon my name is ***** ***** have covered all the common causes of this issue. the injectors were pop tested?

Customer: replied 11 months ago.
Expert:  John Oliver replied 11 months ago.

what have you done with the actual injection pump?

Expert:  John Oliver replied 11 months ago.

so looking in the book and at parts pictures there are only a few causes of this symptom.

1) the pick up pump (if equipped)

2) front seal of the injection pump

3) a fuel injector is over fueling

so with that being said, are you certain that its diesel in the oil? I only ask because from my understanding you have replaced the pick up/transfer pump, replaced the injection pump and had the injectors pop tested on an actual machine. is there anything else I need to know?

Customer: replied 11 months ago.
the pick up pump has been changed out to a 12 volt pump , the injection pump has been changed out for a complete new one, so I will have the injectors re inspected, thanks for the advice if there is any thing else please let me know

I thought about this all night and I keep coming back to the injectors. you can have an injector leak fuel when the engine is shut down and run perfectly fine.

its always a possibility that the injection pump, even being new, can have a small leak past the shaft seal
