Help...6.7 CTD smoking (update: Cracked injector)

The more I load down my truck the better it runs. The most common turbo failures that I've seen is the variable veins start sticking, but you'd notice that with a loss of power, and that "usually" starts acting up around 70k miles. My first thought was maybe a blown head gasket but you said all the fluid levels are normal. Have you pulled the dip stick as well? Oil color and smell normal? Is it making oil?
