1) Look at, test and fix EGR cooler if it is indeed blown.
2) Clean up all soot in the exhaust recirculation system.
3) Evaluate and replace several sensors as necessary
4) After the repairs are done, test head gasket by pressurizing the coolant system.

Thanks again.

If the EGR cooler did leak into the egr circuits and therefore the intake, it will also need new oil. If there is a DOC and DPF, they both will need to be pulled and baked too. Coolant intrusion is a serious problem that effects many systems adversely.
