Tell me what magic makes the lm2 anymore complicated then a dohc gas engine ? Diesels have higher compression. Different ignition source. And as you guys like to state, a 'complicated' emmissions system. Not much more to it.I think there's a bit of minimization going on here. I don't think you can characterize a turbo charged diesel powertrain as, "Oh, we just substituted (but did NOT add) some components around from this naturally aspirated gas powertrain for this turbocharged diesel powertrain." I don't think the majority of the people following this thread would agree with that either.
GM simply f'd up the design and execution of the 6.2L V8 gas engine. There's no way that should be less reliable than the current 3.5 EcoBoost but alas, it is. Heck, it's arguably less reliable than the current Ford's DOHC 5.0 Coyote engine. Don't get me wrong, Ford has had their fair share of problems on their 3.5EB and 5.0 Coyote through the years, but those are largely reliable powertrains at the moment. Because the 6.2L V8 is primarily a GM f up, that doesn't mean that turbocharged diesel powertrains are just as simple as naturally aspirated gas engines (or even turbocharged gas engines).
GM didn't mess up the 6.2 suppliers did. The design is reliable and tried and true but the supplied parts have issues. Namely bearings and lifters.
As for whether the majority of people agreeing or not does not constitute the facts as being different. This is engineering not opinions.
