2019+ RAM 6.7L CUMMINS HYDRAULIC LIFTERS: EVERYTHING YOU NEED TO KNOW

Why did Cummins go from a flat tappet to a hydraulic style tappet?

The reason behind the change on the new RAM 6.7L tappet was to quiet down the engine noise. The 2019-2024 engines run quieter but at price!

Are the Hydraulic lifters on a RAM 6.7L Cummins really an Issue?

Yes, the Hydraulic lifter issues RAM 2019 2021 2022 2023 2024 6.7L Cummins Engines are becoming a more common failure point on these engines. So what is the best thing to do to protect against this issue? Running a 10w-30 Synthetic oil. We suggest using the Hot Shot Secrets or equivalent oil. For the longevity of the engine we suggest changing the oil more frequently than the owners manual suggests. Changing the oil between 5,000 to 7,000 miles is more ideal for overall longevity of the engine.
