Rubber burning smell

[chiefson]

On acceleration especially on inclines there is a oil/rubber burning smell in the cab.... no leaks no idle problems no running problems at all just that smell any ideas?

I am not an expert but first thing that comes to my mind is the serpentine belt. or something is dripping out of the valley of the manifold down onto the exhaust possible fuel leak etcc. just trying to give you things to look at.
