Well, i have posted on here numerous times about a little problem im having with my truck. So, my third opion at the dealer says "they all smoke like that with age". I haven't seen 1. I have, i think, excessive smoke out of my blow-by. They say it's ok. But, is it really? They say i don't have head issue or injectors that it runs fine. This truck is all stock at the moment and im thinking about a programmer and cold air intake, but i don't want to screw anything up that's my fault. So, does anyone out there have an older lb7 and smokes out the blow by?
