Well fellows after at least 6 months of being smokeless, im back, although the truck runs pretty rough right now she fired up and ran down the road.
She smokes like a volcano, spewing ash and soot everywhere. It sounds like a freakin pulling trucks it takes it a while to build boost then she really gets smokeing. Hopefully ill get its all cleared up before too long gonna adjust the valves, and put some fuel additives and fresh fuel in.

 

Well lets hear some details... did you replace that Felpro HG with a Cummins .020 HG? 12mm studs? Firering block and head ?? 60# valve springs? You know, the good stuff!

 

I did get a new Cummins Gasket and thinner injector washers. other than that all stayed same cept fer the oil cooler which was bad (didnt know you could blow both) studs are coming soon, as well as 60lb springs (ill be doing that at school, when i take machening) She was missing really bad but after a while idleing and a very slow creep up the road a ways i was almost in the drive what and she really kicked in. Still smokes like crazy (mixture of white and black), and sputters at low idle, any ideas as to whats causing this.

 

Might have air in the fuel lines. Also fuel could have moisture in it, causing slight gelling and or freezing.

 

Thats what i thought but since im still in school and my buddy is a lincoln tech gradjamakit he swears its the pump, and another buddy thinks its the injectors miss firing. Next time i go home its getin new fuel, fuel filter and additive.
