2006 Dodge Diesel problems

[darr]

took truck in to dealer said all six injecters need to be replaced only $5000...LOL is it unusual for all to go bad at same time??? we told them to put it back together it will just have to sit here in the yard for a while...

Changing the fuel filter should have been the first move. Good luck.

thanks for all the replies...we are taking it to a diesel mechanic we know and and having them replaced...dont want to do one and a year later have to do it again...just wish it was not so exspensive...thanks again

Take it someplace else.
Their statement doesn't make sense when it comes to Common Rail injectors. Unless they charged you to remove and reinstall, and then sent them to Bosch, they did not have them tested.
Also, at 116K they are not all bad. No way. No how.
Injectors are replaced by inexperienced techs way too often.

Here's what can be wrong:
1. Carboned up injector tips.

2. Your Cross-over tubes need to be retorqued to the revised spec.

3.You have a failing coil on one of them. As the previous tester said, this is an easy fix. It's also an easy find for a decent tech.

4. This one is not likely at your mileage but you may have one or more injectors with an excessive return rate. If this is the case then your Grid heater indicator may come on while driving down the road even at speeds above 15 or 20 MPH. This is the ECM's method of alerting the operator to this condition.

First thing to do: Change your fuel filter and fill the canister with SeaFoam fuel treament. Run the eng for about a couple of minutes so it gets to all the injectors. Shut the eng off and let it sit over night.

If that doesn't fix it find a private shop (or another dealer with a certified Cummins tech) that says they can do an injector flow return rate test. If it fails the test or is even close, have them retorque the cross over tubes to the revised spec (which I believe is 42 lb/ft).
The reason your technician wants to replace all the sticks is because he doesn't know how to trouble shoot it. He only thinks that if he replaces everything he it will likely fix the problem.
That would be a huge waste of money and the reman injectors will not be nearly as good as what you already have. It would fix the problem for a while because he has to retorque the tubes during the replacement. But eventually those reman parts will start having new problems.

We owned a 05 Dodge and when purchased it had 3 injectors already replaced. By ~120k miles we had to replace another one so the other 2 got replaced as well.

It happens... :M

BTW... Be very cautious running a diesel engine with known bad injectors. The price tag for the repair can go way up.

[beergardens]

On these common rail diesels, it's pretty common for these injectors to have a lifespan of just over 100k miles. They've all been subjected to the same miles and suffered the same wear over their lives. At this point, I don't think I'd replace just one and risk having another fail in a matter of weeks, especially if it might melt a piston and trash my engine. I would personally find the best deal from a REPUTABLE store and replace them on my own to mitigate the expense as best as I could. I understand that many people may not be willing to do that.

I had a solenoid go bad on one injector on mine. $270 for a reman. I changed it myself. It was number 6, which is by far the hardest one to change. It was still a piece of cake to do it. Any good reputable shop should be able to change all six in less than 4 hours, with a break for lunch.


Btw, if one solenoid goes bad, it will shut off all the injectors on that bank. Which basically puts the truck in limp mode. At first I thought all of mine pooped the bed, but after doing some digging I was able to figure it out.

I'd make sure you know exactly what you got going on before giving a big chunk of change to somebody.

is it friday yet? wrote:
That's seems just a bit expensive. I found these injectors at a store I use for only $849. Can't cost 4 grand to have them installed. I don't have any personal experience with these injectors but others are probably close in price.

Those are just the nozzles (or tips), not the injector bodies.

If you find a whole set of injectors for anything under 3~4k, they're junk.

OP, if you would answer some of the previous questions there's a distinct possibility your truck could be fixed for a few hundred bucks.

[mayo30]

You don't take a cummins all apart to check injectors.

[ScottG]

The OP doesn't seem to want to answer any questions.

[Old-Biscuit]

2006 doesn't mean high mileage.

OP
Some questions that if answered would provide better understanding.
How many miles on your truck?

What made you take it in for repair........what was issue?
Have you had other fuel issues......lift pump/high pressure pump/fuel filter etc.?

How often did you change fuel filter?

[Tystevens]

If it's high mileage (which, I imagine a 2006 is), replace them all at once. If you do one, you'll find yourself just doing them one at a time over the next little while.

Good luck!

this is the dodge dealer we are dealing with..we told them to put it all back together and we are going to take it to a place we know that has worked on our other diesel truck and i know it will be less but still its exspensive...need to float a loan LOL
