Very well said. Ford decided to put the 6.0 and 6.4 diesels in their trucks for 8 years; that is a lot of trucks and a lot of PO'd customers. A visit to any Ford diesel forum will provide a ton of proof of this and a ton of reading.
^ Yet they keep coming back! At least the Super duties got a good power plant now in the last couple years. And they even figured out the factory exhaust brake finally.
That's what I don't understand. If my Dodge just randomly dropped a valve and cratered the engine, or lifted the head, stock or with a little tune, or some other major issue that wasn't warranted by the use it was seeing, I'd drop it like a hot rock.
Coincidentally, even though my personal trucks have been a mix of GMs and Dodges since the 90s, I've put as many miles on every model of F series gasser in the same time period. I get a new company truck avg every year or 2, and of the 10 or so new ones and a few used ones, I've had 2 verifiable lemons.
In the same time period, with around 10 lightly used GMs or Dodges, I've had zero lemons. One Ram with a problem rear axle that was rectified with 2 new rear diffs before it hit 2000miles and a complementary 100k warranty for my troubles. Hence my money goes to the Horns or Bow tie, not the blue oval.
Emissions torture testing on the new diesels, again the nod goes to the Cummins with the Dirtymax in 2nd place. Seen a lot more 3000rpm screamin forced regens on the Scorpion engines than any regens on the Cummins. And if the Cumins needs a manual re gen, it just idles up a bit and does its thing. No need to rope off the "blast zone" around it!
