Wouldn't you expect the water to come out of the drain plug first? Assuming you changed the oil when cold, couldn't tell from the original post.
For the past year, dealers have been replacing the whole EGR unit on recall for Ecodiesels 2014-2019.
While this happens, it is less than 10%. (Yeah I know 10% is probably about 10,000 engines and is unacceptable.) I have been a member of both EcoDiesel Forums since 2014 and read it all. So far I have been a part of the 90% of owners that have had outstanding trucks.
Vern is another one.....
My ED has 341,000 transporting TTs & boats. Motor has never been apart.
