DPF/EGR help!

Ok, i hear you guys! I’m going to get it fixed, and hopefully it was preexiing issues, like you guys mentioned. The guy told me that the injector tip maybe broke and caused to much fuel to go in the cylinder! Truck was knocking, smoking, leaking oil through blow by filter, and using coolant like crazy! It did all this in one day, after running strong for about 14 days! The horse power was set at lowest setting and he raised it to highest setting. The engine has 448000 miles on it! The problems it had prior was multiple dpf failures sensors, pumps, sensors again and again! So that all got solved, truck ran strong then up in smoke! The truck has a DD15! I’m not implying they caused the problem, I just want the truck to be reliable and not break every two weeks, and cost me $2500 every two weeks on dpf and possibly $6000 on this issue! This will run me out of business if it continues!
