The new 2025 Ram 2500 with the updated 6.7L Cummins diesel is here… but as a diesel mechanic, I’ve got questions. In this video I break down the biggest concerns I still have with this engine, especially around the valvetrain and the roller lifters that caused so many issues on the 2019–2024 trucks. Cummins made some changes for 2025, but are they enough? Did they actually update the rockers, pushrods, and lifters, or is this another year of the same design that’s led to failures, tick problems, and expensive repairs?
I dig into what’s confirmed, what’s rumored, and what we’re still in the dark about since Cummins keeps supplier and part-sourcing information proprietary. If you’re thinking about buying a 2025 Cummins, or you want the mechanic’s perspective on the newest HD diesel from Ram, this deep dive is for you. Let’s talk problems, fixes, and what still worries me.
