are lmm's being sold without emissions junk? i live in ca and wondering if all the lmm's have dpf and other emissions crap. specifically ones being sold in oregon.

As far as I know they will ALL have the emission control equipment standard to meet new specifications and laws coming up.

Even in Canada they have all the emission equipment and I believe we do not have high emission requirements. You won't find one without it unfortunately.

lame

The emissions "JUNK" is something that is not going away, so we may as well learn to accept it and live with it. I would not want to get caught removing it, because I imagine the fines will be killers. Also, we have to pass a clean planet on to future generations, which is something I keep in mind when I hear of more vehicles leaving the factory saddled with emissions equipment.

JMHO.

Well, I for one, agree with you. Everyone complained when emissions stuff was put on gas passenger cars. Now, after all these years, they have more power and get better mileage than ever before. The diesel emissions equipment will continue to get better. Removing the emissions equipment violates a federal law. The states may not be checking yet, but they will some day. The federal fine for removing the equipment is probably severe, but I haven't been able to find what it is yet.

YUP!!!:rules:

I THOUGHT, I was TOLD, once that the ones for export to mexico could be had w/o it. Again, this is something I was told, I ahve no proof or definite knowlege. I doubt you could sang one and drive it in the us.

i can not tell no differance with the emmision stuff that is like when evrything went fwd and fuel injection everyone said it was the end look now fwd cars making 400plus hp and people getting more hp out of fuel injection than carbs so just wait this may not be as bad as we think just have to wait and see.

Not sure what people are complaining about when it comes to the particulate filters. I have now put about 2k miles on my new 07.5 and could not begin to complain about the dpf. I have 365hp, 660ft-lb (stock), and when it idles, you can't even smell anything from the exhaust. Not to mention when I put the hammer down with my 33' fifth wheel behind me (10k lbs) the truck just keeps accelerating with NO black smoke charing the front of my trailer. I don't think I could want anything more. Sure... I can't put on a Banks and get 1000hp, but I don't think I would want to jeopardize by 5yr 100,000 mile GM warranty just to melt the tires off my truck. Just my 2 cents.

I'll live with it. It's the reason my wife let me buy one. She said I couldn't have a dirty smelly diesel at home like at work. The LMM isn't a dirty stinking diesel. It's even quiet which is what sealed the deal with her letting me take it home.

I think there is still some old world thinking goin on, I remember customers cars coming in to the dealer running bad, open the hood and all the fuel injection sys has been removed, and a old carb installed, looked like a grenade went off in there then i get to listen to them tell me about how great it runs...lol. Emissons are nothing new, diesels have been left out for the most part, its something we have to do, everyone benefits from it, there is no downside. We now have huge power, no smoke and great engine life. never mind mid teens fuel mileage. Its something new, a change, like most changes it takes people a while to get used to it, once they see that the world isn't ending it becomes the norm, thats what will happen here, after all what choice do we have???...

you're better off buying a 2007 classic LBZ, or a new gasser. The DPF technology is very new, and all manufacturers are having problems.

They all are having problems? What problems are the LMM's having? My experience and virtually all of the posts I have read have indicated they have been flawless.

I agree with MRC, what problems? I sell the GM diesels for a living and haven't had any complaints! Please don't bash gm's technology until you have all of the FACTS!

I THOUGHT, I was TOLD, once that the ones for export to mexico could be had w/o it. Again, this is something I was told, I ahve no proof or definite knowlege.A while back, I researched other possible possible places south of the border where I thought GM might sell a Duramax without US spec. emissions controls. It did not appear that GM sold non-US spec. Duramax vehicle anywhere south of the border (including Brazil & Argentina). If fact, it did not appear that GM sold any Duramax vehicles at all. They do offer several other, smaller diesels, though. I guess if someone there wanted one, they'd have to import them like a few guys in Australia have done.

Mine has been flawless so far. It has also been damn impressive to everyone who rides in it. I think GM got it right.

I work for a Chevrolet Dealership & I have to tell you, so far I haven't seen much in line of issues with these new trucks & the new Emmisions equipment that is on them "cept one for a defective throttle valve but that's impressive conciddering I know my dearlership has sold over 80 alone."

My only opinion about the new trucks from all the manufacturers with these emissions reducing devices on them & the requirement of ULSDF, I think we put them out into the market a little too soon because there isn't enough fueling stations that sell ULSDF so some customers are either having to drive a substantial distance to obtain ULSDF or chance it with LSDF, otherwise I think it was a move that has been too long in the waiting.

Up until 2007.5 (LMM), export vehicles I have seen in Central America (sold to Central America - not driven in) did not have EGR nor Cats, but the LMM will not run in Central America without serious problems until their fuel is changed over, which has not happened to date.

Have 3,000 on my LMM and have had no issues with the dpf at all. No soot or ash on my 5er and no smells in the garage. I use Enkay Rock Tamers when I tow my 5er, I set them back about 12 inches from the exhaust and I feared during regeneration that I would melt my flaps, no such news!. The truck rides and sounds great and tows like a beast. No complaints here except for that damn serpentine belt!

Remove the lettering from the belt so both sides are all black:D .

I didn't see any Duramax trucks listed on GM's websites for Argentina, Brazil or Mexico.

But if it's true that GM sold export LLYs or LBZs south of the border, then somebody should find out what ECM program they had.

That would allow all the EGR stuff, etc. to disabled using an OEM ECM program.

Only manufacturer that a had aproblem with the DPF has since rectified it with a s/w patch, they were having problems BEFORE the DPF was needed so no big surprise there... (Hint: It wasn't GM) None of the dealers here I've talked with have seen a LMM come in for warranty work yet. All the boards I'm on report a resounding Lack of LMM issues. Yeah, I wish my mileage was a little better (don't we all?). The power for me is enough, the lack of black smoke and a nasty tailpipe is great. I don't like having to make absolutely sure I fill up with ULSD, but so far every station I've checked has it.

Overall, MPG PER HP generated has gone up. Average Fuel Economy has gone down because average HP in a car has gone WAY UP...I can remember when 4 Cycl. cars had less than a 100 HP. I'm sure there is one out there with under 100 HP, but I can't think of one off the top of my head. (Prius? Honda Fit?) A lot of 4 cyl. gassers today have over 200 and some near 300 hp! You used to need a big block V8 to get over 300 hp and it got less than 10mpg. I bought a 1978 Chevy Pickup with a V8 several years ago as a mud truck, it only had 175 hp from the factory...

i live in a very rural part of north ca. do most of my driving in 4wd on dirt roads.sometimes 4 weeks before i hit the highway. will my dpf build up? will my regens still burn off enough . dealer is 2 hour drive.

With all due respect guys, its a tad early to preach that the DPF will be trouble free or that GM got it right. Only time will tell that. Nobody really knows yet, the fleet is far too young. Three years and 70,000 miles each truck from now the record could remain flawless, or it could be a common trouble point like the injectors on the LB7 trucks. I am sure they were all flawless only a few months out too ........

Mileage has gone down because cars are heavier on average, not because of horsepower levels.

I agree on the point that cars on average are heavier too, adding to the reduced fuel economy. Higher HP + More Weight = Less MPG...

Remove the lettering from the belt so both sides are all black:D .
This is the first time I heard this as a solution to my belt squeal. Has anyone had any luck with this and how does one do this?

In answer to the question regarding eliminating the emissions items:

There are no variations of the 2007i vehicles (LMM) that are / or will be available without the DPF and the associated emissions equipment. There are no provisions for producing vehicles without the equipment . . period. Not even for export. There are no exceptions at this time.

As far as the regen issue: this is technology that is use dependent. Light duties will be automatic regen; medium duties will be, for the most part, automatic but can be initiated by the driver in some cases.

ULSD is the key for successful DPF and regen life. LSD will kill the system.

The exhaust and emission system as configured is critical for successful operation. Behind the emissions equipment. not so much.

The emissions "JUNK" is something that is not going away, so we may as well learn to accept it and live with it. I would not want to get caught removing it, because I imagine the fines will be killers. Also, we have to pass a clean planet on to future generations, which is something I keep in mind when I hear of more vehicles leaving the factory saddled with emissions equipment.

JMHO.




too bad we are the ones saddled with this junk, not china, india Africa or the mid east... save the planet? sorry, saddle the US consumer with junk in the name of cleaner world... Its a waste of time at this point

HI - I spoke with a diesel fuel dealer in the North Country (NH) about the ULSD. I vacation up there and own land there so being able to fill up nearby is an issue. He told me that all the diesel dealers switched to the ultra low sulphur as a matter of competition AND they all switched last summer. He reasoned that why would someone want to lose a customer to another station because they could fill a demand.

Hasn't Europe and Japan and perhaps some other countries had these requirements for a couple of years now? I thought I had read this on this forum somewhere, but I'm not sure.
