diclaimer; i am not worried about "rolling coal" just the change in color scares me.

my truck used to put out a small black cloud before the turbo would spool. then it would be a slight black haze under wot, not really roll coal, but it made you click. so about 2 weeks ago it started being a gray haze instead, with no black cloud before the turbo spools. i was hoping it was just something fuel related so i waited a couple fill ups to worry. i have zero other symptoms, no power loss, no poor fuel mileage, nada thing.
is this weak, worn out injectors? they are the stock 185k ones with brand new seals. could it be a worn out hpop?
oil still has 3k before a change is due, fuel filters the same.
in the morning it starts up fine, no white smoke when i dont plug in(for people who remember i just had to wait for the glow plugs to warm up a lil longer)
any help is greatly appreciated as always!

 

Is your coolant level ok?

 

It sounds to me like your truck is running better than most

 

coolant is actually low, but it has been since i filled it up because im lazy and it doesnt run hot. its on the list...i actually havent seen more than 1k egts ever, even if i floor it for a long time.(the probe is right after the last exhaust port)

Nick, you think i shouldnt worry about it?

 

Sounds like winterblend fuel and cooler dense air. Not a real problem

 

hmmmm i never thought of that, Thanks for putting my mind at ease guys!

 

I wondered about this too. Never hurts to know fluid levels though. Lol.
