I have 16 K on the truck and have not had a single problem. I just changed the oil, filter and fuel filter 1,000 miles ago. Today I noticed that my fender wells, on the drivers side, both front and back are wet with oil. Not the entire fender well but fron the outside in approximately 6". I crawled fron one end of the truck to the other and could not find anything. I pulled the dip stick and I was on the low side of the operation range.

What is the tube that runs down by the starter, it looks wet, not sure if that is it, I would think if it was that it would be wet towards the center of the truck not the outside edge. Anyone know what it could be?

 

Engine vent tube.Kinda wet is normal.Its opened to atmosphere.Old gas burners were like this before PCV systems were used.
