Okay this EGR thing..

I hope I can explain this half as well as I was just told. When the fuel vapors pass through the EGR tube, vapors go from hot to cold which creates carbons that clog up the tube.

When this happens, the temp of the cylinder walls rise and oil starts getting sucked up and burned out leading to cylinder failure.

My guys say that they are seeing carbon build up and the potential for serious problems with engines 45k to 60K miles. So the tube needs to be regularly cleaned.......
