2004 ford f250 turbo diesel oil leak at left rear side engine mostly when engine is shut off?

Answer 1

Ah the only issue that Ford had with a "FLOWING" oil leak in the 6.0L diesel. You must have a early 2004. In 03 and very few 04 6.0L diesel had the ICP sensor(Injector control pressure) located on the high pressure oil pump cover. This sensor is right next to you hot exhaust y-pipe and is known for leaking all the time. Ford figured this out because it only lasted about a year. Then it was moved to the front of the right valve cover far away from heat. Now what happens if due to the heat it is just weakened and leaks threw the connector not from the o'ring kinda weird. Anyways don't be suprised if when you get the new sensor that they try and sell you a pig tail with a new connector you would need to splice in as well. The reason for this is that all the oil that has leaked into the sensor has weakend the plastic around the pins of the connector which can result in a ICP voltage code which will generate a check engine light. So when I do the repair I do it from the under the vehicle. look up and you will need to remove a heat shield which is held on by a 13mm and two 10mm bolts ( one is blind and you need to do it by feel) then the sensor should be rapped with a heat shield (goes to show how well that worked) unwrap and remove and replace sensor. Up to you if you do the connector I do that splice up top. Remove the FICM to gain more access. Good luck hope this help and stay safe it's hot around those y-pipes.
