Another 2005 6.0 with egr issues

[Keloog]

Hello everyone... Well I have a 2005 f250 6.0 that I purchased from a dealer last month. Ten days after I bought it it began blowing constant white smoke so (assuming it was the egr/oil cooler) I brought it back to ford with a bullet proof egr and a new oil cooler and had them replace them. I've had the truck back just over a week now and until this point have had no issues. This morning on my way to work it began smoking when I came to a stop at a stop sign. I drove a little further and it stopped. I checked my coolant level and it drained half of the degassing bottle. I have cleaned the egr valve and replaced the o rings on it on top of the new egr and oil cooler. Why am I still having a problem?

You could have a blown head gasket. The 6.0 is famous for head bolt stretch especially when driven with a bad EGR Cooler.
