Let me correct my previous post .......
I guess an EGR cooler failure can put enough water in a cylinder that the resulting steam (from hot cylinders) can get by the rings and mix with the oil. I don't beieve that that is all that common though - but it can happen and look like blowby, etc.
Also found this:
............... check behind the water pump on the front cover. The casting sand and silicates that plug an oil cooler will also eat away at the front cover (the water pump impellers sandblast it). When this happens, the coolant has only one place to go, in the pan! You can change a thousand blocks and heads but if you use the same front cover, you always have a problem.
