I am really happy with my 2018 6.7 F350, but wondering if it is really a truck to keep for the long haul. At under 41K miles its on its 3rd DPF. First two replaced under bumper-to-bumper, last one just went in at 39K out of B-to-B warranty but luckily replaced at no cost due to Oil Separator failure and power train coverage. Problem was too much oil getting into the exhaust from a bad separator resulting in a cracked DPK. 2nd DPF was installed for less than a year before the Oil Separator failed and cracked it. Not sure if the same problem killed the first DPF - dealer said it was not, but it took them 2 weeks of calls and data submissions/reviews/tests to the Ford hotline to determine the problem this time. Truck was only showing a P2002 code which most sites posters say to ignore and clear as it means that the DPF is operating at an increased level of efficiency, and the thresholds were not updated after DPF replacement. P2002 can mean its running at increased efficiency - air flow - because the DPF is cracked.
Separator is suppose to last longer with other symptoms before DPF impacts, but it looks like it's a 24k or less maintenance requirement to stay on the safe side. 2018 model eliminated access to replace just the oil filter so you have to replace the entire unit - I've read that some folks replace with the older model to have access to replace just the filter, or add in the catch cans and drippers. I may try one or the other, however, if I did previously it would have voided related elements of my power train warranty for this last go round - DPF is about a $6K/$7K job at the dealer with replacement DPF cost at about $4K.
So be warned that a bad Oil Separator and resulting impacts can be almost as costly as the dreaded CP4 failure. I haven't t seen much around disaster proofing the DPF, other than deleting which is of no interest to me.
I'm pretty happy with Ford as they have kept to their warranty. But 3 DPF's in under 40K miles pretty much tells me I am more than likely to have some serious and (what should be) unnecessary repair costs coming a regular clip. Right now, you can get a good dollar for low mileage super duties making me think long and hard about dumping it.
