Another problem

I have a 2015 f 450 ford with the 6.7 engine. I only have 66880 miles on it. The problem is a replaced both water pumps and the engine had a started to have a whistle when you first started. If I tried to take off before it warmed up it would go into defuel mode. So today I took it out and tried to get it to throw the code and instead it blew off the CAC right at the intercooler. So I brought it home very slowly put the intercooler CAC together took it out almost got 2 blocks before the intercooler blew off again. This time there was no whistle before the CAC blew off.
About 6 months ago I did put on a rebuilt DPF and all new sensors. I find it hard to believe that the DPF is totally plugged again. Does anyone have any idea what is going on? The check engine lite did not come this time,it did the last time .HELP
