Deleting dpf should have nothing to do with engine failure rates. Ford sells these same engines in other countries that do not have such strict emissions laws meaning they don't come with dpf's. Deleting a exhaust treatment will have no bearing on engine performance or longevity.

We had a very early 08 melt down. It was a very busy ambulance. We lost a turbo and had a ton of regens though early on. When the engine went it took another turbo and they replaced the DPF.
Thinking about it though there is a good chance that it ate a ton of LSD. We have our own fuel pumps and I highly doubt that they flushed and cleaned out the LSD before the ULSD went in. Since then no problems and also since the ULSD we have had much less problems with our 6.0s. I'm thinking that the DPF got clogged up and the heat built up.

It was not a pretty start and changing out squads is a huge PITA. I really think ULSD has been the cause of our fleet reliability going way up. I think the decrease in lubricity is a small price to pay for the reduction of soot.

I am confused I though the stock exhaust was a 4" no? I also believed the inner diameter of the down pipe was 3.5" however, that thing was choked up! Cut through that thing a take a look at the crimped bends. Absolutely terrible! That is why I chopped it and am running a ceramic coated 4" dp. I think it flows a little better and spools up a touch quicker. I like it.

Also, I can't see what engine failure would have to do with the DPF delete.. the only thing the dpf coincides with is after market tuning, and if anything would cause a engine to blow would be hot tunes and a heavy foot!

I think the OP was trying to point out that there are probably going to be less failures tuned with DPF delete due to a lot less fuel in the oil problems from the regen.

Have a good buddy and an acquaintance that lost their motors and were tuned and ran hard. Both could be attributed to faulty injectors letting go and filling the crankcase with fuel causing run aways.

And, I haven't heard of many engine failures, tuned or not. Everyone I know that has a 6.4 is happy stock, but unhappy with mileage... or extremely happy tuned, and happy with the mileage!
I also have a friend with 1200 miles on his 6.7 and he is averaging 13-14mpg. Which is what I was getting on my 6.4. So maybe he still needs some break in time.
