[QUOTE="jaybuller, post: 1313438, member: 5347"] How is the blowby out of the oil fill tube at idle? Does it haze at cold start? Does it haze blue once running? I'd say either low or lost compression in one or more cyl or just bad injectors.... I've been down the cold start problem road with 2 of my 7.3 trucks. One turned out to be melted piston ring land lowering the compression causing the issue just as you described and then my current truck that did not have any issues at all until I bought rebuilt 160/30 injectors. The new injectors on my truck caused the issue due to armetuere clearance. (I've been deployed a loooot the last two years so I haven't been able to resolve the issue yet but this winter I think I'll be able to get the injectors out and sent in to be redone [/QUOTE]
