Today I parked my F-250 xlt crew cab 4x4 for about an hour. Before leaving I noticed a small spot on the ground. After moving the truck I inspected the spot an determined it was oil. I got under the truck and drip was found on the right side corner of the transmission were it bolts to the motor. It looked like the oil was running down to this point from a higher place. I brought my truck home and placed a piece of white cardboard under the area and it took it about two mins. to drip. The truck has 20,000 miles on it now. At first I thought the oil was coming from the oil pan but the oil looks like it running down from a higher area. I'm not a mechanic but just asking for information of possibilities before I take it to the dealer on Monday.
Any helpful information would be greatly appreciated. Thanks

Did you look on top of the engine? Maybe the turbo drain tube or something on the oil cooler would be my quess.

Oil leak

I dropped the truck off this morning (Saturday). They stated they would get on it Monday. I looked around the top of the engine around the turbo and the oil cooler but I could not find anything that appeared to be leaking oil. Hope to hear more possible suggestions from you guys. The information will be helpful when talking with the service manger and the mechanic on Monday.

the CAC is the charge air cooler boot that would probably be on the passenger side of the intercooler. I think that is the hot side, but i could be wrong. Its whatever side is coming out of the turbo. It should be a blue boot that connects the cac tubes to the intercooler.

How othen do you still get a few drips after the fix. Is it possible you might still get a few drips after the fix if all the leaking oil was not cleaned up.

possibly. my icp was changed a few days ago and it seemed like it took 2 days for no more small spot of oil. the tech did a good job of cleaning, but i don't think the tech can get it all. my leak was 3 quarts to 50 miles and now no leak.

Didn't the ICP move to the right valve cover on the '05 and new 6.0Ls, along with a redesigned HPOP cover and IPR? I'm watching this thread too as I seem to have a similar issue with my '06.
