I just pulled my engine that I overheated and noticed a few other things when I pulled it and wanted to see if you guys could help me correct the problem. Temps have always seemed to run correct but overheating was caused by the lose of a lower water hose and didn't notice till it was to late, engine started to rattle.ain:

Ok, heres the question/problem. The center of the heads look to be heating up too much and I am thinking the problem might be timing related or EGR related(new EGR)? Heres a photo of what I am seeing. The center of the heads has been BURNING oil at the black area. Seems its been getting hot enough to burn the valve gasket alsil changes were done regulary in the begining but lately for the last 3-4 months Ive been loosing a quart of oil every 2-3 weeks from leaks so I just been adding a quart.
