Not happy!

[Gil Moncrief]

Injectors bad at 139,000. I am the original owner, so the truck has had everything on it since new. Glacier Diesel filtration system, 2 micron, fuel additive (no alcohol in it) with lubricity additive every tank. Clean oil and new filter every 5000 mi. New air filter every oil change. Full gauges, never high EGTs. Looks like bad design/ poor quality issue to me. My 89 1st gen is still on the original injectors and running perfectly at 400K miles. How long have your injectors lasted? Has anyone heard that regular exhaust brake usage has any detrimental effect on injectors? I only tow the fifth wheel 1400 miles per year. Can't understand why these expensive parts fail so early.

Bad QC in 06? And, unless you are operating in extremely dusty conditions full time- your air filter probably works better at 5000 mi than when new. Good luck with your new injectors.

I may be wrong, but as I recall from reading past threads on TDR when I had a 3rd gen and was concerned about injector failure, most failures seemed to happen on the 2006 models.

I think they may have had a bad batch of injectors that year.

 

[Bob V]

What is wrong with them? Are they leaking down or is the coil out? Who told you they are all bad? What kind of problems are you having?

 

[Prairie Dog]

An EB has no effect on injectors - they're never in play at the same time.

 

[cerberusiam]

What has failed and why was that determination made?

What filter are you using on the GDP kit?

The 06's had some QC issues with injectors, you might just have gotten a bad batch. With good clean fuel and additives the injector should operate effectively into the 200-250k range, more if the miles are done in large junks.

Third gen common rail injectors suffer from an inherent susceptability to wear from the high pressures they are contiually used at. This susceptability is also made worse due to the lack of lubricity of US refined low sulfur diesel fuel, any fuel contamination, as well as the lack of oem filtarion that is of sufficiently fine micron rating that was recommended by Bosch and ignored by Dodge.

 

[TCDiesel]

The only way to insure Proper filtration is bypass filtering with (Non certified combustion filter) all these direct injection filtering system you see or read about on the Net help but will not stop contamination, and if these filter that are popular did what they claim I and many other companies would be out of business..........We have many commercial haulers now getting 300K or more with bypass filtering installed correctly. Another aid in helping is do NOT let you tank drop below 1/4 in if you live in warm or hot claimants and 1/2 tank if you live in extreme temperature swings when cold. CR fuel will get extremely hot when constantly returning to the tank 150*+ , CR pumps running temps 130-170* it won't take long to make a few gallons hot, increasing the heat the fuel is subject too.

Hi Todd. Thanks again for the help with my injectors, and the truck runs great now and pulls my toyhauler excellently. You mentioned "by-pass fuel filtering" on the phone, so would appreciate if you'd perhaps list the specific items needed to set up such a system on our trucks. Thanks in advance.

Call me on that.

Call me on that.

Well how about ate least a brief explanation of how it works on our trucks??

How long have your injectors lasted?

My '06 has ~186,000 miles on the original injectors. I did have to replace one due to a non-starting issue, but I think the real problem was that the hold down bolts had come loose. Since I was so far into it, and had the new injector, I went ahead and changed it out.

 

[Gil Moncrief]

The injectors were tested and two of them were leaking, causing smoke and a miss at idle. The smoke smelled of raw fuel, so I knew there was a problem before I took it in.

Fleetguard FF5320 and FF1212. Symptoms were smoke and miss at idle, and raw fuel smell.

 

[cerberusiam]

The 5320 is 5 um not 2 um filter, not bad and better than the stock filter but it is larger than is supposed to be good for the system. An FS1212 is not good a WS either, hope you were running everything thru the stock filter. Still should have been better than bone stock, mine 205k with no issues except they were getting noisy.

If you didn't have codes for the solenoids and it was smoking and misfiring it was a body failure. Probably a bad batch.

Are you sure the 5320 is not 2 um? I put the GDP kit on my truck and it came with the 5320 and claimed 2 micron filtration. Geno's also lists the FF5320 as a 2 micron: "Fleetguard FF5320 2 micron replacement fuel filter for Dodge Cummins Turbo Diesel trucks that have the the fuel system from Glacier Diesel Power installed"

I am confused - or am I mixing up terms? I want 2 micron - if the 5320 is not, then which filter should I be using?

Thanks in advance,
George

The 5320 is 2 um nominal, 5 um absolute. It is probably not 5 um by the current standard either. There are no true 2 um filters by the new standards anymore, 3 um is the best there is. That is how marketing works, they are not incorrect but not exactly right either. They were advertised as a 2 um filter but nominal. Nominal means anywhere from 50-80% effective at that size. Much better than the stock filters but not true 2 um.

3 um has been determined as the cutoof on the HPCR systems where excess wear starts occuring. The difference between 3 and 4 um is so small it is doubtful a quantifiable difference can be made. For that matter, highly doubtful it could be proven between 3 and 5 um. When to comes down to the difference between 3 and 5 um filtration, the quality of the fuel is more important than anything.

The Donaldson P551313 and the CAT 1R-749\750 were old standard 2 um and I think they are now 3-4 um, those are the best available for solids. If you use one of them in conjunction with Baldwin 7977 in the OE hosuing that is the best filtration available. The Baldwin BF1212 is the best WS available. These should all fit the GDP and other standard bases.

03 with 400,750mi original injectors and turbo,fass 150 since new use lucas fuel injector cleaner on a regular basis,never buy fuel from 1 pump low volume stations

Ah, ok. Damn marketing types! I will try your recommendations at my next filter(s) change.

Thanks!
