Idle dd15 get on fuel, stumble white smoke

I'm hearing injector cups/injector cup seals allowing coolant to pass into combustion chamber and burning, thus creating the white smoke under load. I'm going to replace them and the injector o-rings in next week or two. I'll report back

 

Having the same issue with my DD15, truck has def and dpf deleted but I’m not to sure it that the egr was, which is what I’m thinking is causing it, I’ve Been dealing with this for awhile now I don’t think it’s the injectors has to be some stupid emission ########

 

My friend is having same problems with both of his trucks (deleted). He had them deleted last year in July 22 and the problem started around November. One of his truck just had overhaul in January 23 At Freightliner dealership so everything is new but still the problem persists. Took it to dealer 3 times and they don’t seem to figure it out . ( it’s not injectors , Pittston’s, or cylinders or any other stuff that goes around them). last hope is to take it to the guy who deleted it. Anybody had any luck?

 

Anyone had coolent sensor replaced for this problem?

After delete how long you started noticing the problem?
Was the problem slowly progressing?
Did you find the solution?

 

Did anyone solve this issue. I have same problem. Injectors replace. All cans cleaned out. Nothing seems to work.

 

Anyone done the quality control valve.
