We gut the DPF/CAT, and now have problems.

We have an 08 6.4 and gutted the DPF and CAT because it was constantly wanted to Re-gen. It ran good for a few days, but today it was misfiring like crazy in the morning (after a while it didnt misfire for the rest of the day), throwing a P2452 code and when it gets up to operating temp and is under load it blows out a hell of a lot of white smoke until you stop and let it idle. We cant figure out what it could be, what we are thinking for the code though is that it is not reading the correct pressure in the DPF and setting the code. As for the smoke we are lost...I have been reading that whenever you delete or gut the DPF you need a programmer, but would not having a programmer to delete the DPF cause it to misfire and smoke bad.

I dont know much about 6.4 but i think its the sensors are seeing that the regen isnt working and trying harder maybe?? plus i think it goes into limp mode, so you really need a programer

Wow, you actually thought that hollowing out the DPF would change or seize regens. We wouldn't need tuners and DPF delete pipes if that solved everything. There is a ton of info on the internet regarding the regen process and eliminating regens altogether. Hope you didn't ____ the truck up

lol...take it easy! truthfully this truck has been a POS since the company bought it. these newer trucks are all new to us so we just trial and error sometimes. if it f'd up the truck we couldnt be more happy than to get rid of it. ford should have kept the 7.3 instead of this 6.0 and 6.4 crap anyways...so obviously what we did didnt do anything but cause more problems, ok so on to the next step. i guess i will tell my boss tomorrow that 1. we need a programmer to do it correctly 2. buy a new DPF/CAT 3. drain the oil, put a brick on the accelerator and wave bye-bye! I personally like choice 3 so we dont have to keep pulling this junk back into the shop.

Your problem a mechanic for a contractor of some sort that beats the piss out of the work vehicles. When people don't pay the note on a vehicle they generally don't treat the vehicle well or check fluids. I've worked for many operations and I've seen how various employees of companies subdued vehicles to neglect and downright abuse.

I service my rig religiously but I also make it do things that it wasn't designed for but I pay a price to drive hard and fast. If these vehicles are serviced and maintened regularly they generally hold up well. Parts and designs fail in trucks, cars machines no matter what brand that's just the way it is.
