Well boys, in my humble opinion. You are all right. Luke my son, you don't count, your a dealer and you only drive em a few miles. Just poking fun at you ole buddy. I've had a lot of Chevys, &amp; frankly I have given up on them. Gm just seems to produce some real junk. The two diesel chevys I had were nightmares. The gassers have all been lemons. The only exception was my 99 Corvette. Never a problem, zero, zip, nada. Drove it for two years and never once had to take it in.<br><br>The Duramax. I'd bet my teeth on it, it will turn out to be a dog. It is unfortunate, but the dealer does play a critical roll in this. It is a disgrace when they keep your rig for a month, or when they can't fix it, because they don't know how.<br><br>The dodge dealers are no better. We have 5 where I live. 2 are good, both to deal with and in the service dept. The other 3 are what give dealers a bad name. Oh, and they are all 5 star dealers. So I guess it's all relative. But with GM and their diesels, they really should quit trying to invent one and just go to a proven manufacturer and use theirs. Much like the partnership with Dodge and Cummins.<br><br>Not trying to ruffle any feathers boys, just really fed up with some of our car companies and the dealers.<br><br>Another 2 cents ;D

 

I do know the past Chevy diesels have been junk, and you couldn't pay me to drive one... But I have a pretty good feeling about the Dmax. Although it is offered in a chevy, it is not like their old gas-to-diesel conversion engines and I really kind of expect this to hold up pretty well. Isuzu has been making industrial-duty diesels for quite a while, and I just can't imagine they would have any part in producing eight cylinders worth of junk.<br>I do not think the Duramax will ever sit atop the power-pedestal, as I believe the Cummins still has the greatest potential for raw pulling power. I do, however, believe the dmax will prove that it can hold up well to moderate power increases, and I have a feeling based on preliminary research that the dmax's average lifespan will end up in the 200K-350K mile range. This, as all else, is up for debate... But we can only speculate right now.<br>I am sure the Duramax's shortcomings will become apparent over the course of the next few years, but I bet the design fundamentals hold steady while the quirks are worked out. Don't look for GM to replace this engine any time soon.<br><br>Wes

 

I've got two good friends (one's an uncle) with Chevy Duramaxes. Both of them have had zero problems with the engine, the Chevy part is a nother question though. : Little things like broken buttons and ****, dead batteries, and things like that have happened but both engines are running strong. I think they run pretty good too, no way my truck would keep up with them when it was stock. I think GM finally has them a good diesel engine, (did I really say that) I just wish they would put it in the Suburban. :'(<br><br>Ford on the other hand is going to have their hands full with the new PowerJoke, lots of problems already in the International trucks running the new 6.0L. I'm sure it's just a matter of time before Ford finds this out in the Superpootys. <br><br>DB

 

I believe it (Dmax) will be a good engine when they get the bugs worked out of it. It sounds to me like they wanted to get in the HP race before the technology was proven but that is just me talking. Not sure about all that aluminum though in a diesel. Same with the Ford. I just don't understand why the both of them are still working with V8's when the proven way to go for reliability and torque is in line. Mack, another one of the best, tried a V8 for a while and dropped it, back to the inline. We have three V8 Detroits here at work that are always having problems. Course most of that is the way we run them. They are two strokes and they are trying to run them at 1800 rpm fully loaded. Been telling them for years, either turn it up or get an inline that will like running that speed. Oh well. Give them a few years to work out the bugs and then watch out.<br>Disclaimer: I have not been sniffing the printer ink, just want to give everyone a fair chance. I am a die hard Cummins inline six man also. Driving my third one now.

 

I really hope you guys are right. Gm could really use a winner in their Diesel department. THe quality in their products has taken a positive turn in the last two years. But, having been an observer of Gm for nearly 50 years, I'll be surprised if this one works out in the long run. The last one they made, the 6.2, had problems over the entire life of the product. They not only did not fix it, they seemed to compound the problems with supposed improvements.<br><br>So, unless GM has had a recent attitude change, I personally am not real optimistic. Remember, that things change at GM at about the same rate that glaciers melt!

 

Folks,<br><br>When comparing the DMax to the failure of the 6.2, et al, keep in mind that this engine is not GM. It is made by Isuzu. This company has been sucessfully building diesel engines since 1936, and if they weren't making a good product they would have been out of business before now.<br><br>GM in in the same situation as Ford and Dodge now, in that none of them use propritary engines in their pickup. Dodge is Cummins, Ford Navistar, and GM Isuzu.<br><br>This is not to guarantee that the engine, pickup combination will be suscessful, but it stands a pretty good chance, and I'm not seeing evidence of GM having any more problems with their product than I'm reading about Dodge on this page, and Ford over at the DieselStop.<br><br>I have worked both Dodge and GM, and at the present time I prefer the GM. However, if Dodge gets the HO with a viable automatic, and a true crew cab, I could change my mine tommorrow.<br><br>Regards,<br><br>Bill

 

Well said Bill, I see you have made your way over to the &quot;Dark Side&quot; Guy's I have to stress once again that we have sold a heck of a lot of these trucks (Duramax/Allison) and have had no major troubles to report to date. All this down talking about the Dmax is almost getting me thinking that maybe I should drive one for awhile again :Hmmmmmmm, I don't know, I do have two 03 Crew cab dually D/A's coming in ??? :

 

[quote author=DarrellB link=board=8;threadid=9245;start=15#89279 date=1041923964]I just wish they would put it in the Suburban. :'([/quote]<br><br>I feel EXACTLY the same way. Although I prefer the Cummins, a dmax-powered suburban would be awesome! One of my good friends just purchased a brand new Yukon XL (suburban) with the 8.1 liter engine, and that truck definitely flies with that many cubes under the hood... But I can only imagine how sweet it could be with a dmax powerplant!<br>BTW, this friend of mine (fire chief) is looking to replace his Comand truck ('96 K2500 w/5.7L) with a new 8.1L powered K2500. I keep telling him how much he would like the dmax, but he is very set in his ways and is used to the diesels of yore... He just can't imgaine that newer models are actually quiet and smooth-running...

 

I wish Dodge would put the CTD in their Ram Van. But even I, the original GM skeptic, would consider a suburban or full size van if GM puts that motor in either of those vehicles. How about it Luke. Are they gong to or are they already offering it? ???<br><br>I don't tell to many people this, but my wife drives a 2001 Chevy van and so far it's been a good vehicle. Way under powered with the V6, but she has put 30K miles on it and so far I have not had to take it back for any repairs. I've had a lot of chevys and the only 2 I have had that have not given me trouble were a 99 vett and this van. THe 2 dieels were junk and I had a 97 suburban that spent more time in the shop than on the road. Plus about ten others over the years. Really got a sour taste for chevy. But, I am impressed so far with this van. :

 

To date GM has not told us of any firm plans to put the D/A in a burb. But that doesn't mean it won't happen that just means they don't tell us much

 

It would not seem to make good sense to not offer it. They need to do something to keep up with the Excursion even though it is being discontinued. I've heard several people say they would love a burb but won't do it because of the gas it burns. A diesel in the burb would probably sell like hot cakes. I would love to see DC put a Cummins in a long frame Ramcharger. WOW!!!!!<br>

 

Someone correct me if I'm wrong here, but I'm positive that the Dmax injection pump is identical to the Cummins injection pump. Both are two stage radial pumps, with a 9000 PSI primary and a 27000 PSI secondary.<br><br>On the injector front, I don't know what the Dmax runs versus the Cummins, however I'd suspect since they are both Bosch injectors, that they'd be very similar.<br><br>Rod

 

According to this site:<br><br>http://forum.62-65-dieselpage.com/ub...3&amp;t=004791<br><br>You are correct Push Rod. The injectors are Bosch allright. $500 a piece and they keep your old one. Go to the site and read it. I couldn't make up BS that good. <br><br>Not only are they Bosch, but they have to ordered from Germany when one goes bad. Not like mine where I go to the local diesel shop and buy them off the shelf in different configurations and I can get two sets for my Cummins for the price of one installed DMAX injector. Hmmmmm.. Which do I choose????? :
