Burning blue at cold start

hello
New to powerstroke forums, and never owned a diesel before, but did runned it in to some issues

2007 f350 6.0 with 151000 km on it
temperature right now at night is about 10c
here is an issue
truck starts fine, doesn't shake nothing, doesn't look like its miss firing at all, have power even if engine is cold, but it will blow blue when i am moving until temperature gauge moves 1/8 and after good as new.. does smell like diesel tho.. which makes me think its a sticky injector

things i done
Checked turbo for play, seems normal to me
lil oil stains in intake but nothing leaking out of it

also truck seems to wont pick up right away from the light, if i floor it it kinda very slow till turbo kicks in and after goes like a snot. no blowing smoke, nothing at that point

any help would be appropriated

Blue smoke is useually oil. Your turbo oil seal may leak a little wjile sitting, when you crank it up it then burns the oil in the exhaust.

If it smells acrid, it may be fuel from an injector. I had a bluish haze on start up before I changed out all 8 injectors.

Then again, 177k miles on the original injectors may have been part of it lol.

It' a safe bet it is an injector or a few; how many miles on the injectors? Have you kept up with the maintenance? I had a hot no-start due to worn O-rings on the injectors, and just general age of the injectors.

I suggest starting there, but without values of ICP, IPR etc. we can't really rule anything out.

i just got that truck 2 weeks ago, and its got 151000 km on it, i am not sure if those are original injectors or not.
i am getting sct livewire right away here, would that monitor tell me icp and ipr values? and sorry for being dumb but what are they stand for?

You are not dumb at all! I am not sure that the livewire can show the ICP or IPR, to be honest; I have not used one before and am not familiar with that particular tuner from SCT.

^That will give you some parameters to watch/get values for, what they mean, and the values you want to see.
