2007 - 5.9... are the injector troubles over??

[Motorhead]

I have read about the earlier HPCR 5. 9s with injector problems. I just bought a new 2007 with the 5. 9. Is there any info I need to know to keep them in good order? Have they been improved over the earlier engines? I have heard about "no prolonged idle". I would imagine that I should run the finer micron filter. Thanks

read the owners manual. This was talked about at another forum and a Dodge warranty rep stepped in to say, as long as the maintenance intervals are followed to a tee... you would have no problems.



Apparently a big thing with the injectors going bad is people not draining the water from the filter during each fuel up and/or oil change. He also said using bad fuel is the owners fault and Dodge will not cover warranty issues due to that.



It's really sad we can pay all this money that we do for our trucks and this is the thanks we get for supporting their company.

How many service stations are going to want you to dump your Fuel all over the ground? Can you imagine the place if everyone did that? I have had CTS's from 89- 2007. Never had one injector problem. I do WORK my trucks pretty hard and run a mix of Power service and Lucus with every tank. RUns smooth and purrs like a kitten. I also change my Fuel filter every 5,000 miles rather that 15,000 or if I see a sudden drop in fuel economy. I travel a lot and get Diesel from lots of places. 14. 00 filter is cheap insurance.

I was thinking that somebody posted a poll on injector failures which showed a fairly low relative failure rate.

It's my understanding that the majority of people that have injector issues are the ones who stack multiple pressure boxes together. 1 presure box seems to be OK, but it's the stacking that gets them. Am I way off base here?

Not waaay off base... maybe just a little Many have experienced cracks in the injector bodies with just a single pressure box. That being said, no doubt there are more problems with more pressure. More often than that though, it seems the problem is deposits on the injectors from either too much idle time or not working the engine hard enough. Then there's the bad fuel equation... . lower micron filtering =

I had a couple '03s as work trucks. I put 100k on one, and 80k on the other, never had an injector problem, never have used any additives. The only CTD of the five I have owned that ever had an injector issue was my '05 and it was very early on, probably with around 5000 miles. I change fuel filters every 10k, no other extra fuel system maint. My current truck is the only one to ever have any mods on it too. Stock, I think they are really good, very few failures.

Injector trouble

I had an 2003 5. 9 HO and never had any injector trouble. Traded it in December 2006 for a 2007 5. 9. Two weeks ago the dealer replaced #3 injector. Took it back today for the same problem. Their tests indicate that three more injectors have to be replaced. The truck has 11,000 miles on it and is bone stock. I always buy fuel at a Hess station that sells a high volume-mostly to class 8 trucks. Doubt that poor fuel is causing my problem. The dealer hasn't questioned my about where I purchase fuel or how often I drain the filter. How much would these things cost if I had to buy them? Are they covered on the 100,000 engine waranty?

 

[Signal73]

Are they covered on the 100,000 engine waranty?

Yes. However its $100 deductable a visit after 36,000mi.

 

[Cattletrkr]

Yes. However its $100 deductable a visit after 36,000mi.

I just looked at my book last night and it says $100 deduc. after 5 years.

I have a 2005 CR Cummins and have done a lot of reading and talking to various people about the high rate of injector failures as I too am concerned about the injector track record. I have corresponded with Cummins numerous times about injector failures as their engines are used in a lot of other applications besides Dodge trucks. Cummins claims they don't see that many injector failures but then again they use a different fuel filter on their other applications. Last weekend I attended a diesel truck rally and spoke with a Bosch fuel injection rep as well as a Stanadyne representative. I have deduced the following and will modify my truck accordingly. The installation of a "power box" that raises Common Rail pressure above stock levels threatens the reliability of the stock Bosch injectors as increased rail pressure seems to lead to cracked injector tips in certain instances. So it goes without saying that I won't be installing any electronic boxes that increase rail pressure. Due to physical size limitations the best filter available for the stock Dodge fuel filter canister will only permit a filter that traps dirt down to a 7 micron level. It is my understanding that Bosch recommends filtration down to the 5 micron level with 2 microns being the preferred. If you will notice our engines come equipped from Dodge with a convenient all in one fuel filter, water separator and water in fuel sensor. The physical size of this canister doesn't allow for a filter that will filter down to the 2 micron level without causing pressure drop problems. So, to solve this problem I will be installing a large 2 micron fuel filter after the factory filter and prior to the CP3 pump. As with any diesel engine I operate I make every effort to buy clean, water free diesel from dependable sources that I trust and that has always served me well. If you need a source for a 2 micron filter check out the Glacier Diesel Power website as they have some nice filter offerings. I hope this helps and good luck... ... ... ... ..... Lektrikman

I have 191,500 miles on my '06 Ram. I have had zero engine or injector problems. I run lots of Flying J diesel fuel through it using no fuel additives except a little Power Service anti-gel when winter temperatures are below 15 degrees. I use the 7 micron fuel filter from Geno's with a 15,000 mile change interval.



I put 325,000 miles on my previous '01 which had Joe Donnelly installed Bosch "275 hp" injectors installed at about 16,000 miles. Never used fuel additives except winter time anti-gel, also used lots of Flying J fuel, and standard Geno's Fleetguard fuel filters on a 15,000 mile change interval. Had zero problems with it.



I think fuel injector problems with a Cummins are very rare and may relate to bad fuel or modifications.

I disagree. I think the injector failures are more prevelant then you think. Every day I get on the board there is another '03 or '04 with a hard start issue. I just sent mine out to get upgraded to Flux 2's and all 6 injectors needed to be rebuilt. I was told that none of them were firing properly. I have been having hard start issues for a couple of months. I think what we are seeing is two fold. I think the introduction of LSF and that more of the older trucks are hitting the 150k range are contributing to the problem. This is a hunch as I have no data. It just seems like a big coincedence. I think blaming the fuel is bs, because I change my fuel and oil filters on the recomended intervals and I don't have rust in the fuel system. I run a non-fueling TST box on 4 and 4 so I don't think that has greatly accelerated wear, but I could be wrong.



I will be funning a 2 micron filter with my FASS to help... I guess this is the best upgrade you can do to protect your injectors.

$100 deduct is after 5 years on engine and fuel system. Baldwin makes a 5 micron filter that fits the stock location. PF7977 part number. I drain my fuel about every fill up. Alsphalt is a first cousin to diesel and I guess I just add to the mess thats already there. Bad me I know.

 

[Lektrikman]

I've checked the Baldwin website and the P7977 filter crosses over to a Fleetguard 19800 filter which is a 7 micron filter. I don't think the OEM fuel canister can accomodate a 2 or 5 micron filter with enough surface area to keep the pressure drop at an acceptable level and still have a reasonable service life... ..... Lektrikman

 

[DPKetchum]

Its PF7977. I called Baldwin direct way back when cause I wanted to verify that is was a 5 micron. They faxed me the spec sheet on it and assured me it was a 5 mic filter. They(Baldwin) said that Bosche specified a 5 mic and they stepped to the plate and did one. Call Baldwin direct. I looked them up by doing a web search. I was very dubious and took a lot of convincing that it was a 5 mic. See what answer you get from Baldwin.

Luck of the draw I think. I have complained since new about my '07 that runs like my '04. 5 did before it got six new injectors from the dealer with no remedy. On one hand, they tell me it is performing as designed; and on the other they tell me not to let it idle and that I don't work it hard enough often enough. I also had a district rep tell me that "nobody buys a diesel for fuel economy" and "a Hemi with MDS will beat a Cummins for mileage every time". Never mind the fact that the thing sounds like a 12 valve at idle & shakes the whole truck (engine cold or warm). I even got told by a tech that the excessive smoke I complained about was because of having to comply with emissions. How does more particulate matter equal fewer emissions?

If there was not a problem with the injectors I don't think that they would still be on a restricted status for warranty purposes.

If water or other in contaminants in the fuel is problematic why aren't the water in fuel lights being tripped or filters clogging more and why aren't they addressing it with their monitoring systems?

I still think it is the luck of the draw as to whether or not you get good ones or bad ones. If you do/did happen to get bad ones good luck getting them fixed unless the thing quits running completely. Because if it still runs & there are no codes (my case) they won't touch a thing. It will be "performing as designed" or "within specifications".

Good luck.

I don't work my truck hard, and I just use it for around town usage, sometimes on freeway.

Is there a way to get the carbon/other deposits off the injectors without renting something heavy to tow? The only thing I can think of it to rent a tractor (or something cheap) and drag it up in the hills, etc.

If I did do this, about how long and how hot should I get it, 1 hr @ 1200 F EGT?

I guess I could mechanically remove the deposits by removing the injectors?

No problems with my truck, just preventive maintenance.

 

[JHardwick]

I just sent mine out to get upgraded to Flux 2's and all 6 injectors needed to be rebuilt. I was told that none of them were firing properly.

I sent mine in for Flux 1's with 280,000 miles on them. They were flawless and only 2 needed reworked.



NOW, at 340,000 I've got a hard knock while cold :{:-{}
