EGR cooler failures will do this. It can get bad enough to hydroclock your engine and do all kinds of damage. The EGR cooler usually failes because the oil cooler plugged up. If this is your problem, you need to QUICKLY replace both coolers.

BTW - when coolant and soot mix, it can look like oil in your exhaust system.

I don't see how it could.

You can pull your EGR Valve and see if there is coolant underneath it in the intake. If there is, you can be sure it is the EGR cooler leaking. Do this test w/ the rear of the truck at a higher elevation than the front (and after taking it for a short drive).

BTW - If I were replacing the EGR cooler, I would install the "bulletproofdiesel" EGR cooler.
