has anybody heard of any problems with the new 6.6 duramax diesel. i am thinking about getting one. thanks for the help.Gary:beer:

I've heard that they make the Powerstroke look like a big fat pu$$y. But I still won't buy one because it hasn't been proven like the Powerstroke and judging from the older 6.2 that GM put out, it could be a huge flop.

J. J.

Thats the same boat im in. I would rather have a chevy, but the powerstroke diesels are tried and true. They are made by international. The only drawback is the tranny isnt as strong as the allison. I am still wondering how well aluminum heads work on a diesel.

The 6.2 wasn't the flop, the olds derived 5.7L 350 diesel engine was the huge flop. That engine tainted the 6.2 engine. The 6.2 was built by detroit diesel, not a converted gas engine. The 6.6 is a beast. I test drove one. Doin 80 mph down the freeway and didn't even know it until I looked at the speedo, and inside it was quite. We were talking and with the engine running and the hood up right in front and were able to carry on a conversation over the engine. Kinda hard to do that with a ford or a dodge. Also with the heads, they did a test, I forgot what it is called but they inject cooled water into the engine coolant to see if there would be any warping and there was none. They did this test twice as long as they have done to any other engine, including there gas engines. This is the second time chevy has had aluminum heads on a diesel, the other engine was diesel V-6 in the early 80, but that too was tainted by the 350 diesel. On another note they have made a few revisions in march of 2002 engines, just like oil pumpshafts and small things, nothin major, 2004 is when they are going to do something to the duramax, don't know what it is yet. Oh and there makin a 4 cylinder and V-6 duramax, still developing the V-6, but the 4 cylinder is done, now there testing it, to go in an Izusu suv and a unowned gm suv, I don't remember the horsepower, I think it was something like 150 or so, and it is looking like 47 mpg for gas.

All I can remeber about the duramax right now

The 6.2s reputation was tarnished more by the fact that it was a piece of shiat than the fact that it's predecessor was an even bigger turd. :flipoff2:

RIGHT

I got a 6.2 in my 90 Chevy 4x4 and it kicks ass!!! I haven't had 1 problem out of it since it was bought 4 years ago! I get 23 mpg driving anywhere I want and thats on 33's. I haven't even got 14 mpg out of ANY of my past chevy trucks. I even bought the "Banks Sidewinder Turbo" for it last week and I haven't had the time to put it in yet but I can't wait to have it on there. I have a brother in law that has a 88 6.2 in a 4x4 and he has put over 500K on the motor and all he had to put on it was 2 alt. because the bearings wore out! Duramax is the gonna be the best diesel made and the most powerful. As for the reliabilty they were in conjuction with "Isuzu" in developing this motor and they have been been diesel pioneers for 20+ years...... :D :D :flipoff2:

Spectacular. :D

Don't be baggin' on the 6.2, fawker!! My K5 has a little over 322,000 miles on it and it still runs like its brand new. BTW, its all original. :flipoff2:

Not trying to rain on your parade or anything, but if the 6.2 is so reliable and as awesome as some of the folks in this thread are implying, how come it's not a popular Jeep swap or any other swap for that matter? I mean, it's been widely known that a diesel is a superior rock crawling engine for a long time. And also, how come the Cummins and Powerstrokes are so much more popular?

Not saying youre wrong, just wonering if I've been missing something that's been right in front of my nose for a long time.

6.2 swaps are very common. Take my truck, for example. :flipoff2:

A diesel would be nice if they were cheap to find or fix. There are many 350's you can find for 100.00 and fix up! As far as the Cummings/Powerstrokes selling more......it all depends where you live.....

The reason you don't hear about them swapped is because you can't find them in a salvage yard!!! Nobody wants to get rid of them, and in the event they EVER fail then its from VERY POOR maintenance in which case its screwed.

Not only that but its not cheap to build a 6.2, not to mention the immense weight of the things...

Maybe the cummings and powershaker just are more common POS that don't last long and are throw to the scrapyard instead of fixing them.

Deisels are not popular swaps into smaller vehicles because they are too big & heavy.

Hey, I'm a big fan of the 6.2 (& 6.5) but it was never meant to compete head to head with the PowerSmoke and Cummons. The 6.2 was a product of the fuel crunch, the others are spin-offs of heavy truck diesels.

Swap material? Well it might be a little heavy for your Jeep but they ARE swapped. Europe and central america are the hot spots for diesel infusions.

I've got a motor pool full of 6.2's and Uncle Sam been running them since '84. You do the math, it's alot of trucks. I think they would have had a pretty notorious rep if they were REALLY that bad. :usa:

I would say the number of 6.2s I see in the junk yard is about proportional to the production figure for a given year. (ie if 15% of trucks were diesel, 15% of the ones in the yard would be too.)

LOL...Yeah its amazing how trashy they are...even AM General thinks so i mean look at how the early hummers hold up:rolleyes:...and now they run those junk ass 6.5's in them... :flipoff2: I think the ford and mopar fools are just in denial

I've known several hummer owners (As in 4 - 5 of them.) and they have all always complained about problems with the 6.2.

I've also lived in CA, MN, MI, FL, MD, and GA. I have been through almost every state in the mainland. I would say that the Powerstroke and the Cummins are by far more popular no matter where I've been.

Just observations.

So anyways Back to the original question. The only problem with the duramax so far is it is too damn quiet.:zzz:

I picked up my '02 Duramax/Allison pickup about a month ago. It's an extended cab long box dually 4x4. I haven't had any problems with it and I don't expect too. I'm struggling to make it though the breakin period (must.. resist.. temptation to use full throttle :( :p ) but lets just say I have yet to loose a stoplight race. :D

The Allison tranny works great too. I picked up an 11' camper last weekend and brought it home. The tow/haul mode works as described and will actually use engine braking to keep my speed constant on downhill runs. I barely use the brakes to go downhill or stop for a light. It sounds like I'm double clutching a stick shift as it slows to a stop.

If you're considering a new truck you'd be stupid not to check one of these things out. I can hardly wait to put the camper on and put the Jeep on a trailer behind it. It's gonna be an awesome tow rig.

[edit] - Forgot to add. Check out The GM Diesel Page (http://www.62-65-dieselpage.com/cgi-bin/Ultimate.cgi) for more info on these trucks. Lots of good info there.

well all i could say is when the 6.2 came out in the early 80s none of the companys had a good diesel and now all of the big 3 manufactures have a descent diesel. I have friends that have powerstrokes,and cummins and they are good diesels even though they would trade them for a duramax in a second but the problem being you cand find a duramax 5 or 6 years old.
I purchased my duramax in october(crewcab shortbed)and i love it. So far the best mileage i have seen is just over 20mpgs but that was with like only 40lbs of air. So it only gets better(i hope)
But hey too each his own! But i will see ya at the top of the hill!

thanks for the info guys. as soon as i get enough for a down payment i am going to get one.thanks Gary:)
