Ok guys, new to the site and, well, new to diesel trucks. Bought a high mile (104800) 08 F450 to serve as a tow rig for our newly aquired 5th wheel home away from home.
We start this saga with enough regens to choke a donkey. Around town I was in regen at least 3-4 times a day. Went to the stealership, where the service writer advised me to do a DPF delete. Ok, read TONS of threads on the site, saw similar folks with similar issues, and dove into the DPF delete.
H&S Mini Maxx, DPF/DOC pipe completed. Problem solved right!
So now the truck has white smoke that emits from the exhaust once the motor warms up. Heavier on throttle. Smells like coolant. Great, ordered the Sinister EGR delete kit. Can't hurt, the mini maxx already has the EGR turned off anyway. Guess I know why it was clogging up the DPF so much.
Interestingly enough, when I looked at the DPF closer, it had a replacement date written on it of 10-15-2011. Now I'm wondering if the previous owner had it worked on under warranty and they failed to diagnose the real problem and just threw a new DPF on it?? Trying to get the Ford service records now. Not that it will do me any good, Ford will still deny any further warranty work.
Fingers crossed, more to come.......
