blowin white smoke

[ASG]

Has anyone seen white smoke out of the tail pipe ? Seems like it only happens when the engine is warm at half throttle. Seems to lose power at this time. According to egts its not too hot. What is this??????????

I had it happen to me while the truck was in park while I was un loading my boat the other day.....I pulled the truck up and parked it...ran like crap....then after about 5 hours on the boatd I got in the truck to pull back around to the ramps and ran perfect.


Nest morning it did it again upon startup for about 30-60 seconds...since no issues...I dunno....almost like it was trying to go into regen.

Sounds like the EGR valve may be sticking

Can you tell if it is water vapor from coolant or does it smell like fuel?

Mine is not vapor...mines is/seems like EGR issues or like it was tryingto go into regen.
