12.7L Detroit vs 14.0L Cummins (opinion)

It's a setting called half mode IIRC. It cuts fuel during warmup. You would notice a change in sound at 125* and 150*.

I think it does cut out half mode when brakes are released. I always waited till I hit 150*. Half mode is programmable in the ECM.

It's used because of the smoke caused by low compression pistons.

 

I got a new gasket for mine, but it was too big. I cut it at an angle, shortened it to the proper length and no leaks at all.

 

Sorry. But I just don’t like the 12.7 at all.


I freaking love it!!! What a sweet engine. Completely happy with mine. It really beat my expectations. I got it with a fresh rebuild, so that was even better! I was told to run it a while before changing to AMSOIL (which was great when I used it for a classic Caddy I had). I’m about to change the engine oil and the transmission fluid. Already did the rears and threw new cab air bags on there. Also changed out my fuel tank strap rubber and evened out the tanks.

 

While I had the valve cover gasket off I said let me un####it and add the red white and blue.

 

You doing it yourself, or having a shop do it? Anything I can tackle myself I do it. I did not do my king pins and alignment though. KW did them.

I just picked up a new sidebox for my skateboard. That’s the next project.
