Injectors are now on back order to the tune of 28,000 and they can only produce 7800 per week but they are averaging 7600 new orders per week so they can't catch up. They haven't had a recall because they wouldn't have enough injectors in stock to replace all that they would need.

http://www.dieselplace.com/forum/smileys/Unhappy.gifWOW!!!http://www.dieselplace.com/forum/smileys/Ouch.gif Where did you hear or read that? How similar are the injectors to Cummins design, i thought they were similar?? Could be some head rolling over this....

My local dealer was replacing a set Friday. The Tech said it took three weeks to get them. He also said that GM sent them a memo/letter ??? that said that 1 to 4 micron dirt in the fuel was causing injector problems. Imagine that! Going with a secondary filter early on looks like one of my better decisions. (knock on wood) I asked if this info was a TSB. He said: No Later!

7800 a week max sure seems like small amount for any automotive supplier. With all the CNC equipment out there the majority of work could surely be outsourced.

You would think GM would have spec'd a better fuel filter.


The fact that many have invested in a pre or post OEM filter with 2 micron filtering is probably the best money spent.


I am sorry that I did not put one on sooner than I did, however my injectors show excellent balance rates and the truck runs as new.


Hopefully anyone who buys a new LLY puts a secondary filter on right away, like the first tankfull.........

You have to assume that the Cummins will see injector problems as well without a better filter set-up, unless Cummins spec'd a 2 micron or better.

Where you come up with all this stuff. You just tring to convert ushttp://www.dieselplace.com/forum/smileys/Clap.gif

Hoot,


Here of any injector problems w/ the Cummins. I haven't heard of any so I assume all is well correct. Where did you here about the GM injectors?

Injectors are now on back order to the tune of 28,000 and they can only produce 7800 per week but they are averaging 7600 new orders per week so they can't catch up. They haven't had a recall because they wouldn't have enough injectors in stock to replace all that they would need.





Repost from the Cummins site?

Or Ferd

Wonder if those Dodge transmissions are on back order. Dad is on #3. They also changed out his evaporator core a couple of times and it started leaking again this summer. They won't warranty the new cores so they pop him at every visit. Service dept says it's not their problem. He plans on going back to GM again due to Dodges lack of customer loyalty after the sale.

Hoot is taking his turn at stirring the pot.http://www.dieselplace.com/forum/smileys/Clap.gif


People say that the Cummins has a similar injection system. How about failures for them?

I'm not really stirring the pot. If I find good news I'll post that too. It's not that hard to believe beings so many LB7's are coming into injector replacement territory (0-150,000 miles) http://www.dieselplace.com/forum/smileys/HiHi.gif kiddinghttp://www.dieselplace.com/forum/smileys/HiHi.gif

Just ask the techs. Don't go by me.... I'm a Dodge boy now. I've been researching alot about the Cummins use of the Bosch system. It looks like Cummins took some precautions like the edge filter they put in the fuel feed tubes....

"Each fuel injector connector tube contains an edge filter that breaks up small contaminants that enter the injector. The edge filter uses the injectors pulsating high-pressure to break up most particles so they are small enough to pass through the injector. The edge filters are not a substitute for proper cleaning and covering of all fuel system components during repair."

I think Cummins has a jump on the issues that GM is having. The Cummins/Bosch system doesn't use descrete lines fitted to the injectors. They plumb the fuel using holes on the head so there are less problems associated with line leaks or corrosion.

As far as the injector innards are concerned, I have no idea if the Cummins/Bosch injectors are designed significantly different durability wise. Maybe the edge filter addresses something getting by on the Dmax system. Why else would Cummins do such a thing?

a bear.. evaporator core... why do they keep going? I would try a different dealership. I have not read of multiple evap core failures. Wouldn't doubt if they used the same one as GM. I do agree with you on Dodge after sale loyalty. It's the pits. Transmissions? I guess I'm here to prove my own smack talking wrong. Hey.. I got 11750 miles so far and can't complain. Truck has been great.Edited by: hoot

Lets see 7600 ea. = 49400 trucks per year if changing all 8. That would be near 20% of the Duramax population based on sales of about 250000 units a year. That would mean near 2000 members here would have had their injectors changed. WHERE ARE THEY? http://www.dieselplace.com/forum/smileys/HiHi.gif

Spank.....Spank......... Ooooh, that's gon'na hurt. http://www.dieselplace.com/forum/smileys/HiHi.gif

They're all here http://www.dieselplace.com/forum/smileys/HiHi.gif and some have had multiple sets!

Seriously.. ask the techs. I'm not making up numbers to piss anybody off.

Check your numbers. How many engines have been built? 300,000 or so? times eight? That's 2,400,000 injectors out there.Edited by: hoot

I believe it. Neighbor with an 03 was without his truck for a month due to no injectors available. He got so mad at GM he traded it on the spot for a F**d.

Welding shop/pump service in town has an 02 DM that has been in the shop 7 times with only 70.000 miles on it.

Nah can't be true.





At that rate and with the internet today xspecially the Diesel Truck forums ,Dodge Ford inpaticular.


I could see the HeadLines.


I wish them GM boys would clean up after themselves,I was out the other day and there was Maxi-Pads stuck all over the side of the road.





Mac http://www.dieselplace.com/forum/smileys/Shocked.gif

Maybe just one guy had his changed 2000 times. Or two guys had theirs changed 1000 times each. Or 4 guys had theirs changed 500 times each. Or. . . uh, never mind.http://www.dieselplace.com/forum/smileys/Clown.gif Tough nut to crack that there high pressure through a small hole problem. Would be nice if someone could really figure it out and share with the rest of the world, of course that won't happen.


Dennis

Called my service manager today to ask him a question about installing my cab lights.


While on the phone, I asked him about the back log. He said, "He heard there was but he has not had any problems getting them so far". He stated that he is seeing less than 10% of the trucks they sell/service with the injector problems. Mine was one of them.


He has a couple sets in stock and said they can get additional sets in 1-2 days if needed.


He heard that some Dodge boy in <st1:State><st1:place>Tennessee</st1:place></st1:State> was spreading these rumors around. http://www.dieselplace.com/forum/smileys/HiHi.gif

Not pissed at all. Just questioning the creditability of those numbers and their source. They seem inflated.

Hoot; I had nothing better to type at the time. I have an early 02 (built Sept 01) I expect the Injector Gremlins to strike anytime. How will I handle it? Truly afraid to find out. So is my wife.

Wonder how it would work getting injectors shipped from Missouri? (Sorry if I mispelled)

If the 1 to 4 micron particles are what's making the injectors fail.....then why in HELL dosen't GM put a better filtration system on the truck from the factory http://www.dieselplace.com/forum/smileys/Disapprove.gifhttp://www.dieselplace.com/forum/smileys/Ermm.gif that seems like a no-brainer

There is no "Official" reason for failures. Ball seat erosion could be caused by particles in the fuel. Cracks in the injetors could be from heat, or God knows what.

I believe people with aftermarket 2 micron filters were/are having injector failures.

No ryme or reason as of yet.

hey Hoot


Did you get a plow for you truck yet? Or are you scared the weak Mopar trans will blow up?

Actually a new set of injectors every 150K would be money well spent compared to buying a new truck. Right in the ball park of replacing that Mopar/Ford transmission in the same time frame. http://www.dieselplace.com/forum/smileys/HiHi.gif
