ok , sorry for the time it took me to write again , after some digging around I definitely have some water coming in to a piston its water locking at start up a little bit ,still no sign of water in oil but like one of you guys said it's evaporating during the day not enough to discolor the oil . I think its got to be from compression to exhaust looks to me more of a cracked head than anything , my mechanic does not want to touch it till after the year that not convenient to me , truck is working every day 300 -400 miles a day , I'm inclined into doing it my self would have to find torque specs and where to buy the parts , have looked at ebay they sell new heads for around $ 600 and new bolts and gaskets . all injectors are about 1 year old , what do you all think , worth doing or just waiting it out its a better option . I have a barn shop compressor and a lot of tools done gas engines total rebuilt chevys 350 6 in line fords , worked on a cummings 5.9 , a few engines but never worked in the larger diesels engines . might me more than I can chew . any thoughts ?
