So recently I have been getting an exhaust smell in the cab of the truck. How long it has been an issue I have no idea. Last month or so I have had the windows closed due to cold weather. I was under the truck a few days ago checking on stuff and I didn't notice anything out of the ordinary. Is there somewhere I should be looking in the engine compartment? Tried to search for stuff on here but had no luck.

looking at this again, I have noticed white 'smoke at stop lights or when idling while parked comming from the FRONT of the vehicle. Seems that is the time when I smell it the most. While getting the plow hooked up, I noticed that the smoke was comming out of the breather tube on the right side of the engine. How much is normal? when I looked at it, it was a constant puff-puff and it is 'wet around the outlet. Any thoughts??
