Blown egr cooler but could there be other problems? please help

[06HD_F_250]

OK yesterday my check engine light came on code p1335 which is bad egr valve. I took it out cleaned it up and the truck ran fine, then last night about 30 miles from the house started to act up again , having poor throttle respose and decrease in power i just figured it was dirty again so when i got home took it out and now it is wet inside the egr valve and trucking is white smoking bad. going to put in a egr delete monday . My question is that will a bad egr valve and cooler cause the truck to run terrible with mainly no power or do i have more problems?

You can count on the fact that your oil cooler is clogged and needs replacing. If your smoking bad and drove it like that you may have also blown the head gaskets. This is the classic domino effect with the 6.0. The oil cooler clogs causing the egr cooler to rupture and the coolant in the cylinders causes the cylinder pressures to get excessively high and stretch the head bolts resulting in blown head gaskets.

A monitoring solution like the Edge Insight, or at least a ScangaugeII to monitor the coolant temp and oil temp would have saved you from this. If the oil temp exceeds the coolant temp by more than 15 degrees running unloaded at 65mph the oil cooler is clogged and needs replacing. If not taken care of at that point what you are experiencing now is the result.

Don't drive it until you get it fixed.

I have a scangauge and never got deltas above 8 before or during this happening. Has anyone experienced alot of loss in power with just a blown egr cooler?
