6.2 black smoke
 

hey friends need some help. i have 6.2 diesel and im wanting some black smoke to roll, how do i accomplish this? im new to owning a diesel so i have no clue how any help would be appreciated.

Rolling black smoke is a waste of fuel and leads to premature engine failure if you still want to waste money you just turn up the injection pump

yea after reading about the damage that can be caused by doing that i am just fine with my smokeless still running 6.2 diesel.

i dont wanna roll black smoke, but when i get on it, i wanna see something! stacks are a bit worthless without at least a little smoke

My truck has a horizontal stack:tttt:

My 6.2L smokes quite a bit during heavy acceleration, so I usually try to back off or gear down, but I didn't realize that it could be causing premature engine failure. The smoking got a lot worse after I had new injectors installed a few years ago. The diesel mechanic said they calibrated the injectors and that it is nothing to worry about. Still, if I tromp it I can make copius clouds. What kinds of engine problems can this cause and should I be worried?

Piston rings mostly

Thanks for the info. I think I might have the injectors checked.

Keep it running clean! Mine just hazes a little under hard acceleration, and that'll mostly disappear once i change injectors

More risk to the piston tops than the rings with excessive fuel, remeber diesel is a light lubricant and why you still see crosshatching in the cylinder bore even years after running the engine, also excessive fuel can dump past the rings and into the crankcase diluting the oil. A small puff of smoke on hard acceleration is normal until you are scavenging enough air to complete the burn, rolling coal especially in a 6.2 n/a engine is bad karma.

Turboed engines also roll it until the turbo is spooled sufficiently to supply air for fuel being delivered, rolling coal is not an example of power made that one has.

It is actually a showing that the tune is too fuel heavy until the turbo spools to use the fuel being commanded, I'm more impressed with a setup that puffs, smokes a little then hauls ass down the street/track.

100K is basic life of the 6.2/6.5 injector, while you may have worn injectors, black smoke generally an indication of lack of air, what kind of air filter are you running and is it clean? Have you or anybody prior to you owning the truck ever gone in and adjusted the fuel metering screw up in the IP ? That also can cause mucho black smoke on a n/a 6.2
