Coolant in oil (Oil analysis)

Now, I am concerned. The owner is going to fix repair replace whatever it takes to solve this coolant in oil issue. So I am trying to be proactive and find out myself what the issue can be. The truck is at a shop and they are trying to troubleshoot it.

If you don't yet own this unit, I would highly recommend that an overnight pressure test with the pan removed to eliminate head/gasket/liner issues be performed. It is at the point mileage wise where these issues will begin to show up, and you don't want to be left "holding the bag" requiring an inframe in a couple of months.

edit: Your signature says 450hp, so I'd suggest that head/gasket/liner issues are less likely than a high hp version and I'd still bet on the EGR cooler, but a potential $35k risk vs an overnight cooling system pressure test is a pretty good self assurance policy
