First off sorry for all the posts,I'm just trying to work all the kinks out of my truck. Second,I saw this video http://www.youtube.com/watch?v=ITiIM4RzHeM and noticed it sounds just like my truck. The guy says its a headgasket but my truck runs just fine I think. It does occasionally use some coolant after really heavy towing, not much though, and it never runs hot. Its probably normal but I just want a second opinion so i can sleep better. Thanks everyone.

 

Leaking injector pull them and have them pop tested..

 

Thats what I initially thought. The good thing is that it's getting a new ip and injectors in a couple of weeks.
