Not necessarily. V means more moving parts. Here is an example of a part with finite lifespan, the timing chain. The ED has 2 camshafts and 2 timing chains. Cummins BT6 has a single camshaft that is Gear Driven. however, I would expect the ED timing chain to last the life of the vehicle (say 200k to 300k miles).Good question, aren't v8's known to be more reliable and better for long term ownership?
This is what I found. The engine has been around in some form or another for many years and VM Motori has a lot of experience with it. Anything with a turbo needs a good maintenance schedule.2.8 vm diesel engine life - AUSJEEPOFFROAD.COM - AJOR
What you find is a long reputation of reliability for the engine. It has a history of marine and automative applications with long-term reliability of design and components.
