Compare your coolant temp to your oil temp. The 6.0's are known for plugged oil coolers. Lots of small fins and buried in the middle of the valley.
Do you have a coolant bypass filter? You should ;)
The SCA's come out of solution and tend to accumulate in the cooler. It takes LOTS of effort to flush it all out. Many do the flush and then buy a new cooler anyways, and add a coolant bypass filter.
But be sure to test and maintain the SCA level in the coolant, the 6.0's are a bit picky about it.
Have you had it bulletproofed by a reputable place? I'm sure you know about the head gasket horrors and EGR plugging problems (easily fixed).
The turbo is VGT, which has moving vanes that tend to get sooted up. If you pull it an open the turbo, they can be cleaned easily, too. If it is hanging up, that could make some serious turbo heat, which could move into the oil as it is cooled by the system, into the coolant...."it all runs downhill" LOL.
BTW, this advice is generic to the 6.0's. Your E450 may have some slight variations ;)
