thanks for all the help. i'm thinking based on input i've been getting the fuel in the oil is normal. it was only a little overfull and the customer doesn't remember the last oil change so i believe it's been awhile

So i've been able to avoid being diesel certified for the first 19 years of my career. Now i've been sucked. I'm hoping i can get some help with my 6.4l. i've got an 08 f-250. it runs great but the check engine light is on. i've got codes p008e fuel cooler pump control circuit high p0101 maf performance. p0128 t-stat stuck open all in memory. i did some inspecting and found what looks like oil in the coolant. it's black and doesn't smell like diesel. i also have diesel in the oil. the oil is thin, overfull and smells like diesel fuel. is there any known issues or a common source for the oil and coolant to be contaminated. thanks in advance
