Bluish smoke

hi i have a 2005 ford f250 6.0L powerstroke. im recently having bluish smoke to me it smells like normal diesel exhaust comming out the tailpipe at certain times, mostly at idle like stopping at a red light but usually only last a few seconds. Other times it last for a while and is fairly thick. it doesn't seem to have any lack in power, no sputtering, starts fine. I had a diagnostics done and turned up with two codes P0404 and P0405 which both has to do with the EGR valve but i figured it should be white smoke not bluish with a egr problem but i don't know much about a diesel engine thats why im asking anyone who could help me. it has around 105,000 miles on it. any help would be greatly appreciated. thanks

I had something similar happen to me a few months ago. I had bluish/white smoke/mist coming from the tailpipe at idle and more when accelerating. Ended up being a blown head gasket. I have also had EGR valves go bad, however, when an EGR valve goes bad you typically don't have any power when stepping on the throttle. If you are experiencing EGR codes you might have a bad EGR cooler. I would start by pulling the EGR valve, give it a cleaning and replace the two rubber rings and see if that helps, its cheap and not very difficult. Or you can always delete the EGR system.
