When driving my truck up a long hill ( 10 or more miles),sometimes I will smell a burning rubber kind of odor in the cab. If I pull over and open the hood I can smell it around the air filter area, but the degas bottle is not leaking coolant, nor has the level gone down at all. I will also smell it on a long gradual hill when pulling my trailer. The smell is only there for a minute, then it's gone. The truck runs great. Does anyone have any ideas what this could be?
Today I opened my hood and found a big orange rubberband sitting on the manifold next to the turbo. I had been smelling the same thing for a while. It was a big thick one about 6-8" inches in diameter by about 3/8" and I have no idea where the thing came from. I only have 2400 miles on my truck. I had to bend a coat hanger to get down to reach it. Is it it some kind of gasket?

Reason: left out detail
Had the same rubberband on my 06 dealer said it was left from factory assembly. nothing to worry about but will take awhile for the smell to go away for good.
My gut feeling is that the rubber-like odor is coolant, but I can't find any wetness anywhere. Can this be an early sign of head gasket failure? It happens at about the same distance up a long hill that I drive daily that goes from 2000 to 6000 feet elevation. The hill is pretty tough on most vehicles, b/c you see a lot of cars overheated on the side of the road in the summer.
