After taking my 02 LB7 truck in 4 times and having the injectors replaced 4 times because they kept leaking, and yes the dealer said he has never seen that happen before, I’ve been noticing when it’s cold out and I start my truck it blows a little white smoke tell it warms up. I also had the glow plugs checked and they replace 2 of them. Once the truck is started for the day it does not do it tell I go to start it the next morning. I was wondering is this normal when it gets really cold out or am I going to have injector problem again?

this is normal, especially when it is cold. It will be alot louder on start up in cold weather also

Totally normal and less painful seeing that cloud of unburn fuel at $2.67 than it was at $4.67!!!

You my have a bad or going bad CP3 pump,had 5 sets of inj. in my 02 gmc in the first 185,000 miles,after the last set 143,000 mile back I pulled the CP3 out and put a new pump in.When I went inside the old pump 1 of the 3 bore looked like shit,the pump was killing my inj. The balance rates are all under 3 on the set I have with a 143,000 mile (IT WAS THE CP3)
