Looks like Cummins learned that the 2019 release had significant design problems. Let's see if they finally fix them for 2025.

Interested to see if the aluminum head is real. I haven’t seen that noted as a change. And not sure I’m in favor of it.
Cast iron block again = good imo but wouldn’t prevent me from buying a cgi engine.
New hpfp is not a CP4.2. It has a designation of CP8. But very similar in appearance to the cp4.x. Not a lot of info to find. As the cp4 ages it seems its reliability is much better. Hopefully the cp8 or whatever it is has basically the disaster prevention kit built in.
Oil and fuel filters suppose to be easily accessible now. That’s a plus.
Glow plugs? Meh…not bad but I’d rather have the grid heater. Guessing this change is 2 fold. Primarily for increased combustion temps sooner for some obscure emissions regulation. Said it’s for more airflow but a in tact grid heater will flow those 2025 power numbers with ease. Side effect they can brag about no more broken grid heater bolts.
Biggest news is the Powerline trans. This has been delayed for years. Like 5-6 years. I would buy a first year Powerline equipped Ram. Not sure I’d buy the first year engine changes.
Un fortunate because I’m really wanting/needing to get into a long bed 1 ton. Still couldn’t give me a Flowerjoke, GM sells too many Dmaxes to lower the price and Ram is now “new” albeit they are practically giving away 2024 68rfe diesels. I may actually eat my words and go pickup one of them 2024 diesels for low $50s. Wish they made more of the 4th Gen’s with the G56 before they discontinued them. I’d take a low mile 2015-2018 with a G56 in a heartbeat!
The struggle is real…lol.You forgot to mention the new 8 speed Transmission. Supposed to be a game changer, but dont know to much about it yet.
So here's a quick look at the 2025 6.7 Cummins
Aluminum head
Back to cast iron block instead of CGI
New Water pump
CP4.2 pump
Oil filter cartridge cannister

Looks like cummins can't standardize their engines for the long run like they used to.
its probably because of emission changes. and trying to keep up to ford and chev in the power wars. little harder with two less cylinders on both fronts. I would be interested to find out why they are going back to cast iron blocks.
