Hello and thank you for your question,

In most cases diesel fuel in the oil is caused by either leaking injectors or the return lines are leaking. Start first with removing valve covers to check for any leak on the return lines. If no leaks are found with the return lines , then replace all the injectors. They are very common to crack and leak into the engine. Unfortunately there really i is no good way to determine which injector it is leaking , so it common practice to go ahead and replace them all which should solve the problem.
