Fuel in the oil? Make and model of the engine?
Let me opt out and get the right guy to help. Do not respond to me or it locks the question.
Hi Jaime, My name is***** will be glad to try to help but first I need the complete model information and engine serial number from your engine ID tag so I can identify your engine and correct fuel system.
Click on this link for some troubleshooting information on the 6HK1. Let me know if you need more help. I log in in between jobs so there might be some delays in response but I will always reply back on my next login if more help is needed.
injector repair info
Most common would be the injector pump seal. You would see this with the oil pan down and fuel leaking from the front timing cover area. Injectors you would need to pull inspect the cups and test the injectors, then reseal.
You would still see where the fuel is leaking from as it will run out and down the gear train. What is the complete engine model and serial number from the ID tag?
Hi, what you will do is unplug the crank/cam sensor which disables injection for starting. you should still have fuel pressure staged in the rail and also while cranking with a no start you will still be able to identify fuel leaking down the gear train.
6HK1 Id tag
Right front, top part of cylinder block below number one exhaust port.
