Leaking hoses. Anyone else?
More for curiosity sake, are diesels supposed to be oily and dirty in the engine compartment? (This is from the silly wife who doesn't know anything - at least that is what the dealer thought.) I understand a little road grime and such on the hoses around the engine compartment, but I would expect a new engine to stay fairly clean (have not been able to wash it during the winter) am I wrong? In particular the blue turbo piece, ours appears to be saturated with oil. Of course, "this is normal" is what I was told... before they decided to replace it (on Nat. Backorder). Some of our other hoses are moist where they connect. I have a hunch this is in part due to the clamps, what do others think?
A little nit-picky I know.
Thanks for the input.

If your talking about the CAC tubes yes its common. The rubber boots do get dirty. Unclamp them and there might be oil inside the CAC tubes themselves but just a little. CLean up the hoses with brake clean. Have they popped off?

Have the same problem the blue hose going to the turbo noticed oil spots all over the soft hose.Wiped clean and rechecked after driving another 400 miles poped the hood and hose is spotted with oil stains from inside the hose itself.Engine has no oil spots anywhere else all other blue turbo to intercooler are fine so far was told dealer was going to aquire a replacement hose and call me well thirty days and still waiting.Did get documation on problem on ford data computer.Had to almost strangle the shop forman to document & spend 5 min to look at the hose.Was much more customer freindly after i dragged the dealership manager down to his desk.

Some 1999-2003 Super Duty/excursion Vehicles Equipped With A 7.3 Or 6.0 Ford Navistar Diesel Engine May Exhibit Oil Leaks Around The Charge Air Cooler (cac) Tubes On The Hot Side Of The Cooler (drivers Side Of The Vehicle Near The Intercooler). This May Be Due To Oil Contamination In The Cac. Clean The Cac And Air Dry With Shop Air Thoroughly Before Reinstalling. Some 2003-2004 Super Duty F-series And Excursion 6.0l Vehicles May Exhibit A Lack Of Power And/or Low Boost Pressure Condition. This May Be Due To The Hot Side Charge Air Cooler (cac) Tube Blowing Off. To Service, Replace The Cac Tube/hose (single Generator 4c3z-6c646-ba / Dual Generator 4c3z-6c646-ca). Clean The Hose Mating Surfaces To Make Sure They Are Free From Oil, Then Position The Rubber Connectors All The Way Onto The Turbocharger And Charge Air Cooler Fittings Before Tightening The Clamps To 12 Nm (9 Lb-ft).
