^that was supposed to say "wouldn't" be the first time I learned the hard way
Headed home today if I feel good after the 6 hour drive at 90 decibels I might try and get them installed.

okay.just swapped injectors. upon cold start after purging the fuel system of air, same amount of blue smoke. grids never came on but right now its about 60 degrees and I had it plugged in for the last few days. this time it didn't sputter and run super rough like normal though, and it sounds a little different. I do have a video. will post if I can

That looks like exactly what mine just did at 55 degrees here in south east Colorado, I know my grid works, ip is "stock" except for fuel pin and I have different injectors. Today is the first time I've noticed it. This morning at 30 degree start no smoke or rough idle.
I know ic motors grid is supposed to cycle at 60. Is it possible that at around 60 degree that the initial start up cold fool sensor thinks it at temp so grids wont cycle?

that's definitely still a good amount of smoke/haze at idle. especially concerning that it's unchanged from the last set of injectors. at anything over 40-45 degrees, I would not be blaming temperature/grid heaters.
as chip recommended, I guess try turning down the fuel screw a turn and see what happens? wish I could be more help. other idea, which is more grim, is that oil or fuel causing the blue smoke?

Another member has recommended to check the diaphragm in the pump for oil leaking into the fuel which I can try and do
It has also been recommended to run a Cetane booster
Unfortunately it's storming out and I got called into work, so more truck maintenance will have to wait until next weekend

Man those sure look like some really thick sealing washers on those injectors. Aren't we suppose to use the thinnest, to get them closer to the bowl?

Haven't heard this. These are the ones i was told to run with these injectors; both the 190s I pulled out and the DDP stage 1s.
Anybody else heard this?

I re-sealed the turbo as well as did valve stem seals last December and a head gasket and studs.

sounds like you've covered all the other bases. i'd start fooling with the tuning. fuel screw and timing. just do one thing at a time and test until you find some resolve.
