Something that is very different with diesels is the rate of change with the manufacturers coming out with new versions which fix problems with prior year models but introduce new flaws. Gas V-8 engines can be sold for decades with minor changes (post unleaded gas) but GM for example has had 5 different engine designs in the past 10 years.
Really? Care to elaborate on the 5 different engine designs of the Duramax?
LB7 - The Original
LLY - Known for overheating, but had VG Turbo
LBZ - Fixed overheating, most reliable known
LMM - 2007 emissions compliance
LML - 2010 emissions compliance (DEF)
Completly disagree, as it is the same basic design with enhancements "required" to meet stricter emissions laws and continue to boost output numbers.
Now if you had used Ford diesels as an exammple (6.0 turd, 6.4 semi turd, and now 6.7) you would have a solid argument as these are actual "different engine designs"
Agree to disagree I guess. Just noting that GM identified the engine as 5 different designs. However, I'm under the impression the LBZ block had some reinforcements and foundational changes that make it more desired than any of the other pre-emissions duramaxes no?
