First thing I typically ask for is error codes (using a OBDII reader) and fuel pressure (idle to WOT at highway speeds).

The worn exhaust side turbo seal could be very important since it is a source of unregulated fuel. I don't think I have ever hear of that causing a runaway on a 5.9 though. White would be raw fuel, Valve adjustment? 300,000 is a lot of miles if it was never done.

I have the same problem with mine. The smoke does look white most of the time, but smell it. I had someone start it up for me and the smoke had a real heavy oil smell to it. I also had the cummins shop in town test the blow by and they said my rings were in check. I am almost certain its the turbo.

IF it is a turbo seal and it is leaking bad enough to produce visible smoke you might want to stop driving it until you get that fixed. That is a lot of oil and could possibly lead to a runaway situation.

if the oil is leaking on the intake side. it will get sucked into the engine causing runaway. exhaust side oil seal will just keep blowing more and more white/blue smoke.

True, wasn't thinking of that side of it.

Intake side should be easy enough to check, pull the boot off the intake horn, and see if your getting oil residue. It would have to be a substancial amount of oil to travel all the way through the intercooler. I think it would be worth checking first at least from a safety prospective anyway

As far as I know, you should check for end shaft play. It should not move in or out at all. I'm not sure, but I don't think it's supposed to move side to side at all either. I would pull the turbo off just to see what the exhaust side looks like. See if it is leaking back there. Someone else might jump in and give more suggestions too.
