There is a mist of oil on the underside of the hood above the oil filter cap area. The oil filter cap doesn't appear to be leaking. A call to the dealer got a response of "This is normal" but it's still going in for inspection.
What could be causing this oil leak evidence?
Pretty sure it's oil.
It's a very common problem and the most often misdiagnosed. More often then not, it's the CAC line, more specifically the inadequate clamp holding it. The oil filter/housing is not under enough pressure to spray a mist up to the underside of the hood. The other problem on some the 6.0L was a leaky turbo lube line. The problem I had with my 2004 was a leaky CAC.
