Replaced the #1 injector last month. First injector was replaced at about 30,000 miles, next one at about 80,000 and then at 102,000 at my expense. The first 3 were all on #2 bank. The #1 injector last month was at 200,000 miles.

Just wondering, are you using the factory fuel filter only or have you added additional filtration?

Haha old thread!!

Im at ~151K and still orig injectors...

My 05 CR had 120k on it with no injector failures. We see the 03-04 commonly lasting 160k and the 04.5-07 about 120k miles. With the duty cycle that the injectors see (often 4 injection events for each rpm and at pressures up to 26,000psi) the internals do wear. I like the filter kits from vulcan performance. We sell a lot of them. Starting with good injectors helps too. We have a Common rail machine and it was surprising to see the quality of some 3rd party reman injectors. For the money and reliability I prefer the genuine bosch or the brand new Bosch Motorsports.

I have the FASS fuel pump/fuel filter set up. Their fuel filtration is much better than standard. I think it's 2 or 3 microns. The human hair is about 5 microns. The FASS fuel filter is a spin on. The MOPAR filter is 7 microns. Those injector nozzles are so small, the best filtration only makes sense.

Running smooth @ 237K miles, 30% towing.

03 HD 5600,
Making oil since 68K miles. Now 82K and last Backstone Lab check indicated 2.5% fuel at only 3K miles. New injectors going in within the month. Funny though, it runs so nice one would never think there was a problem. One question though, my tail pipe used to run a light grey color. Now it is almost a black as my 95 ran. So, to you 03 HO guys, does your tail pipe run clean?

Always had a sooty exh tip. Never thought it should be any different, being a DIESEL and all.

My 03 has always had a black tale pipe and during an extended tow it would get some soot on our trailer too.

When I rebuilt my engine I had all the injectors checked. Two were out of specs so I replaced them. I don't know how long they were in there but the truck had 352k kms ( about 218k miles ) on it when I got it. I know of a guy with an 06 who finally changed them for the first time at 650k kms ( about 403k miles ). His truck is always on the hiway pulling RVs. David

311K+ on OEM injectors, no smoke, 100~200 rt daily driver. Bought 50HP nozzles in 07 but never installed them. Service OEM7u and GDP 2u every oil change. (15K) CLEAN fuel is #1.

TGVET, when did you install the 2um filter? What mileage/ age?

 

[TGVET]

A looong time ago. Probably in 06 or 07, less than 100K ? I'd have to look in my maintenance log for sure.

 

[Wayne M.]

I just installed a home brewed 2um about 1k ago. I'd love to make it another 100k but I don't think it will. I see light haze in the morning.

 

[jwduke]

46,xxx miles and none yet!

46,xxx miles and none yet!

A 4.5 and ONLY 46K ? I had that the first 12 months... :{ You have what is called "a garage find".. Get that thing out on the open road and stop using for grocery runs.:-laf

I had them replaced at 100,000 and I again had problems with them at 143,000. I was having the same problem the second time with the engine not idling rough in Park. As long as I had a load on the engine I had no problem. On the second change we also replaced the Fuel Pressure Sensor, which I am thinking this was really the problem. But Southwest Diesel did tell me that (3) of the injectors failed their test. So we decided to replace all of them, because it seems when you replace just a couple of them the have a tendency to make the other injectors not work as well. What the heck, it is only money..lol

I had one go out on me 2 months ago about 30 miles from home. I had it towed home and looked up the procedure to locate and replace the bad one here on the forum and did it myself in the driveway. That makes 4 replaced and 2 original. If I had the money, I would have replaced all, but didn't work out. The first two were replaced under warranty, one at a time. At 102000 miles, the third one went, completing bank two, and the dealer wouldn't fix it under warranty. I had 199,850 miles on the truck when the 4th one went south. I bought a new truck in the panic to get back to work, but decided to work out of the '07 for as long as I could. But, lucky me, I got laid off the job I was working on and had been with the company for 7 years. At my age, I was looking to keep that job and it's benefits until I decided to retire, but I guess I'll do it differently now.
