So I was finishing up doing the first oil change on my truck yesterday at 3,000 miles and I decided to check the air filter to see how it looked after a few thousand miles of wear and tear. When I popped open the intake and took the filter out, I found a very interesting thing on the filter. As I expected the filter still looked practically brand new, but there was a very obvious weird pattern of dirt on the filter. All the dust, dirt and debris was concentrated on the farthest right portion of the filter. For those of you who have seen our filter, there are two main strips down the filter which kind of divide it into three equal size sections. Almost every bit of the dirt was concentrated on the far right section and almost nothing on the other two. It was a very obvious difference in the amount of dirt collected too, it wasn't any small difference. Anyway, is this a problem worth having the dealer look at? I haven't noticed any weird engine problem recently so I am not particularly concerned, but does anyone know what could be causing this?
