On my 14 E350 cpe. just removed the air filter assembly and found oily substance in the intake where the two parts attach. Also the outside under this intake has black oily residue. Before I did all this,I noticed that the ring clamp securing the filter housing to the intake was not cinched. Fitting seems pretty secure but if not 100% could this be the problem. Front of engine compartment does smell a little oily when hot. Still under Cert. Warranty. Question, should I have Dealer look at this, clean it up and secure clamp or clean it myself and leave clamp as is for further easy removal?

Com'on Friends, some of you must have some thoughts. Lets get some discussions going.

I would ask dealer to check especially since its in warranty. Kind of sounds like a small seepage somewhere that's blowing onto things. If you're smelling burned oil it must be getting onto surfaces somewhere.

x2 on using your warranty, but take pictures before and after.
I bought dealer-serviced car before and had to spend $600 on parts damaged by mechanics while servicing the car.
Kinked hoses, to save 70 seconds on removal, bend fuel line clips, to save 3 minutes on proper removal.
Taking car to mechanics too often makes chain reaction that never ends.
