I just don't like the way they cool the injectors. For me, the old 12 valve cummmins with mechanical injectors is the best.
Most diesel trucks now have that system where they use engine oil to lubricate and cool the injectors, and I have had too many experiences with that producing problems. I've gone through three powerstrokes injectors. Two cat diesels that I could never get running right because of the injectors and hpop.
I would buy a duramax, but it wouldn't be for the engine, it would be for the truck and transmission paired with it.
I love those Allison transmissions. I've got 4 of the R2000, and one of the r1000 Allison transmissions without park. All paired with 5.9L and 8.3L inline cummins.
The only cummins I've got in a light duty vehicle is a 6.7 in a 3/4 ton dodge. It does fine, but that getrag transmission is about to give out after pulling trailers for 80% of its 155,000 miles.
Good thing injectors are cheap, right?! That's what always makes me scared to buy a used diesel. I think they realized those old diesels were built too well. ********.
