Hello, my name is***** code indicate excessive fuel return from the injectors. Check the injector return flow. The limit is 6 oz per minute with the engine at idle. Make sure to separate the return fuel from the high pressure pump from the injector return fuel. Try re-tightening the fuel connecting tube nuts. Torque the nuts to 37 ft.lbs. If that doesn't help then replacing injectors is next step and a common problem. Let me know if you have more questions, thanks.
Yes they are under valve cover and would eventually dilute the oil. You will need to remove return line to measure. Let me know how it goes or if you have more questions, thanks.
