Will someone please help me understand this since I am the owner of a high mileage diesel. Is that $5000 for 8 injectors? If so do they really all go bad at the same time? That sounds like an awfully expensive repair bill.


My question to the service writer exactly.
He said most of the cost is labor as an early model Duramax involves more work when replacing injectors..
Besides his test showed three and possibility four injectors not working right.

My only symptom was lots of smoke at idle. It seemed to run fine.


So I have to ask on a scale of 1 to 10 with the 1 being the smoke from the bad injectors where do you stand on this scale with the new injectors. was the smoke at Idle that bad?? you said it seemed to run fine otherwise? did you go somewhere else and get a second opinion??? service writers make their living writing service tickets, did you go to the forums suggested and do some research??

Did the service writer tell you how he came to the conclusion that the injectors were bad. All diesels smoke in some form some worse than others. My daughter just had this happen with her car, she went to 1 of the 2 dodge dealers in town for a light issue on her car. the first dealer told her she would need a whole new wiring harness to the tune of 3500. well she called me crying I had her take it to a second dealer they fixed it for $225 parts and labor, she chose the first dealer because it was Much closer on her way home from work.

Lots of stuff I am not trying to be truckulent with you but before spending 5000 dollars I myself would have been looking to other options and seeking second opinions. there are code readers out there that can tell you the Bias of each injector and tell you what injector is bad... did the service writer Show you the bad injectors or injector???

Personally I would have lived with the smoke.

I Apologize if i have offended you I was not trying to. and for any one else having the same issues get a second opinion.

again I am not trying to flame you and I am very sorry for your troubles.

thebigtiny,

Your questions are valid and yes spending 5000 dollars on a unneeded repair is crazy.

My truck started smoking at idle some time ago. We have tried to ignore it for maybe the last year.
We have monitored the crankcase oil level since the truck was new. Understanding bad injectors can cause an overfill condition. That has never happened to my truck.

The smoke at idle was becoming very noticeable. Not black smoke buts lots of blue/white smoke.
Wife complained about it a lot.
When I drove the truck into the dealers service department several employes remarked about my smoker.
The dealer wanted $100 as I remember to test the truck to find the smoking problem.
Later that day the dealer reported three injectors bad and possibly a forth. I do not know what kind of test if any was done.
The repair receipt DID NOT show the $100 test fee. Just parts and labor for the repair.

After the repair at idle the truck has no noticeable smoke. Believe me the wife didn't until she looked for herself.
It also seems to run better with more power but I am less sure of that. It also seems slightly noisier, but we have been driving the wife's car and so that maybe why.

We have used this same dealer for many repairs and services on our two Chevy's over the last 5 years. The service has been very competent though a bit expensive. We have never even thought of asking to see old parts because the repairs fixed problems.

Not ofended in the least. In the big scheme of things car problems are small problems.

Oh yeah the rebuilt injectors cost $300 each.

2000-2003 Duramax had alot of problems with the injectors. Thats why you'll see alot for sell between those years. If you want a good reliable diesel truck 99-00 Ford F350 Powerstroke with the 7.3L Turbo was a good reliable truck. Also Cummins has always been a engine that out beats any diesel engine. After 2003 Duramax can be good and reliable.

Are there any Techs on this board who have been able to 'bench' these 'bad' injectors?

Old timey injectors, needed to be cleaned/rebuilt. They were mechanical, pressure operated injectors.

I'm wondering if that is what is happening to these, or are they defective 'electrically'?

All Duramax's are high pressure common rail injection systems with electronic injectors.

They too can suffer from sooting if the driver doen't work the engine hard periodicly ala the "italian tuneup".

Again I was not trying to be mean in any way. I just do not trust service writers from my own bad experiences with them. and again I am sorry about your problems and having to spend $5000.
just for kicks i went to the Diesel place chevy forums and went to the LB7 motor section and searched on SMOKE issues. seems very common some had fixed their problems with high quality 2 stroke oil in 2 or 3 tanks others had other minor issues that caused their trucks to smoke. BUT many had the bad injectors and that is just the pits in your case. I hope you get a long service life out of this set of injectors. And I hope you get to travel some reguardless of the financial set back.

Before I bought my used '03 Duramax I did a ton of research, I joined a few different forums and found out about the 7 yr 200,000 injector warranty. When my truck showed symptoms of bad injectors, hard starting when warm, I took it in to one of three dealers in my area.I was loaded with Duramax knowledge when speaking to the service writer. He kept the truck for 3 days and told me it was the crank position sensor, I disagreed but he was insistent. As I stood there when truck was done with the writer the tech tried to start the truck and it had the same hard start condition. I was fit to be tied... I said "now do you agree that it is the injectors?". He wanted to keep the truck for more tests and if it was the injectors he would be a week to order them. I demanded my truck, drove it to another dealer, they tested and confirmed 3 injectors were bypassing fuel when warm. They replaced all 8 the next day and I was on the road to Tahoe that evening, and have been running strong ever since... Moral of the story, not all stealerships are the same. If your gut tells you your getting ripped off go find another.

If my 99 Ram diesel goes to the boneyard... I would go gas.. the price of diesel is so high it does not make up for the additional miles.


Where I live in California regular gas is selling for $4.35 a gallon and diesel is $4.49 or 3% more. I get 20% better MPG with diesel so I am paying less for the fuel overall.

It is still cheaper than Europe where gas is 1.69 Euros per litre, but then in Europe people have the option of using fast and efficient and cheap trains and light rail trams and subways, unlike the USA where we are forced to own and maintain cars to get around.

Time to buy stock in the gas companies as they continue to rake it in big time with huge profits year after year after year.
