think all the uneven corrosion on the pistons could have contributed to the broken crank?

I doubt it,, After seeing how OUT of balance these engines come from GM, I would be very surprised if my balanced motor with melted pistons, was more out of balance....JMHO...

Have you checked to see if all the glow plugs are working? If you don't have a CA emissions truck, burned out glow plugs won't set a CEL. If more than a couple are burned out, I would say that is your problem.

was my thinking....if the glow plugs arent heating the cylinder enough, proper combustion will not happen until the clinder temps raise and i think that woud cause the white unburnt diesel smoke

I was hoping for burnt out glow plugs. That's why I changed them. I also put new rails on with them. With no improvement.

Glow plugs should be 12v at the plug when they're on.

It's possible that maybe one side (one rail) of glowplugs is out. I would check this.

Also worth doing a compression test IMO.

My truck was doing this exact same thing before i put it up for the winter. I had the race tune loaded and was white smoking pretty bad till it warmed up. So i was worried and loaded my towtune and that fixed it no white smoke at all. So i come to the conclusion that it is caused by maybe to much fuel and or timing maybe on the race tune. Load a stock tune or lower hp tune and see if it stops smoking:thumb:

I tried doing that last winter and it had no effect.

If you need a compression tester I have a brand new one sitting in the garage I could loan you. Or you can get yourself a cheap one from Harbor Freight for around 30 bucks IIRC.. I would start there.....
