I was reading the comments and Cummins have soft aluminum pistons that burn through on a hard pull, their weak point. As for the Duramax: chevy engineers dont know how to build a real diesel engine... the 6.2 was a failure as was the 5.7 (Oldsmobile).

@dollman0 your trolling ability leaves much to be desired.

[bnowlin001]

No wastegate on a variable vain turbo.

@bnowlin001 I have to beg your pardon on this. I have a 07.5 lmm and it does indeed have a wastegate on it.

[bnowlin001]

@LRWarrior If you've put an aftermarket turbo in your truck, then your are correct. But a wastegate is not needed in a variable vane turbo. The purpose of a wastegate is to open to control boost pressure. The vanes in a variable vane turbo "open" and "close" to do the same thing.

@02duramaxlb7 kid just stop..ford stucks ass!

its all about the cummins!

@dollman0

5.7 was a failure? Their LS1's are 5.7's and are some of the toughest motor's built... as are their older 350's..

I've worked in industry, i've seen it all, Duramaxx outlasted them all.

@dollman0

6.2 wasn't a duramax, good try though

Please!!! Can the guy who uploaded the video and did this work tell me what did he do to get this sound?? Awesome sound

[dslpwr]

By far best sounding Duramax video I have yet to see! Love it keep it up!

@schmitz1988 I am really happy to waste days of my time fixing a manufacturing defect in the Duramax. If you don't know what I am talking about, try replacing the reluctor ring on the oil pump drive gear after all the bolts fall out on the highway when the truck only has 36,000 miles and the dealer don't want to fix it. I had to buy a butt load of special tools to work on the Duramax and the shop I work in don't have anything for this engine. The fun part was torquing the flywheel 180 degrees

[schmitz1988]

@dollman0 the 6.2 was never meant to be a puller,didnt even have a turbo. it was meant for longevity and fuel efficiency..and the 5.7 was a rushed mistake,why the fuck are you putting down technology used 30 years ago? so what does the duramax have to do with the 6.2 and 5.7? nothing lmao trying to put down a new and completely different engine compared to a 30 year old dinosaur lol good argument

@foxracing279 It's the same with the LML duramax (2011) its entirely in house now.

[foxracing279]

@BBTthetank I was saying that izuzu designed their engines. The guy I was talking to was saying that chevy cant design a diesel, well they didnt. Just like ford with navistar-international, and dodge with cummins, chevy had izuzu design the duramax. Like I said I dont know about nowadays though. I know the 6.7 powerstroke is being built in house by ford.

[BBTthetank]

@foxracing279 The crankshaft and the rods are built in Japan. But the rest, plus full assembly takes place in Moraine, Ohio. Dmax isnt the only diesel; The International DT466 (commonly found in medium duty trucks and buses) is also partially built in Japan. It's not because they dont know how to engineer, it's the cost of labor, paying all them union workers, and having to put up with all the government bullshit rules and reg's. So all 3 automakers HAVE to outsource labor just to make profit.

@dollman0 The Cummins (5.9 and 6.7) are 100% cast iron. That means internal and external. Why do you think the cummins weighs the most even though it has 2 less cylinders and 30% less moving parts? None of the company's except ford are making their own diesel. The Duramax (Isuzu and GM) and the cummins are both amazing motors. I miss my cummins, but I got a Duramax because it wasnt badly priced, and its loaded to the tits. The Cummins had just rolled 1.7 MILLION MILES and was still goin strong.
