G.M.'s in line 3.0 diesel video.

Has to be following SAE rating or something and imagine it's standard fare for light vehicles. Otherwise, agree, it's shooting yourself in the foot to say a vehicle engine, pretty much any engine is only good for 150k these days.
Engine looks interesting. Haven't seen a cutaway view or watched all these videos but if the engine requires removal for long term maint items then that's a bad design.

Time will tell I suppose. Only new baby diesel id buy at this point would be a Ram, not because it's in a ram but it's the only one with some years under its belt.

What's different here is that major components (oil pump belt mainly) will need service at that point, and it does not appear easy to get to. Timing chains rarely fail without warning, so you can just keep on running them until you start getting telltale timing chain slap or valve clatter.

Just because an engine is "only" validated to 150,000 miles does not mean it can't last much, much longer.

I'm interested in this. It isn't that I don't trust you, but where do you find documentation that all vehicles under 8500 pounds are validated to 150k miles? Is that the "medium duty" spec comes in?

I also want to say that I read somewhere that the Ecodiesel's life expectancy was the same mileage.


Here is another video that goes in depth on that 150k life expectancy.

Engineer Reveals All! Duramax 3.0L for Silverado

Probably rust out before 150K miles.

About 8.5 minutes in they state the 150,000 engine life, and they say "same as the Ford". Which Ford are they talking about? The new 3.0?

Wonder what the 3.0 Eco Diesel was validated for, anyone know?
