5.9L Cummins Piston Damage

[@leel6429]

2005 5.9 3500 Here with 280k I absolutely love this truck and will keep her till the end. Rebuilt the tranny after towing heavy loads daily for the first 165k. Other than that it has been normal maintenance and that is it. I am still on origional injectors. Truck still has day one power.

[@chennemeyer]

Nice scientific flavored, thoughtful approach to resolving problems, if I had a diesel and a problem I'd trust you to fix it

[@chevyblock550]

For the most part, the Common Rail 5.9 Cummins is a really reliable platform. If you don’t keep up with the fuel filters to make sure the sensitive injection system never gets damaged and if you don’t change the oil often to make sure the oil doesn’t get dirty and hurt the lubrication, they will die. Keep up with the maintenance and they’ll last just as long as a 12 valve engine.

[@ILikeWafflz]

I got my 04 at 45k. I was getting 15 MPG, which I thought was kind of low, so I looked it up and found out that an injector going bad will mess with your mileage. I took it to my brother's dodge guy (who he's known for 4-5 years), did an injector test, and found that injector 6 was firing at 88%. Got it replaced (didn't help the mileage though), and I am now at 61k, and I'm glad I caught it, cause it could have done some serious damage if I left it. I have plans of getting a 2 micron filter system very soon.

[@markmadden8495]

definitely don't agree with the "black smoke isn't normal" for like 20 years but overall good video, informative

[@1966cambo]

on computer controlled engines it is not normal.

[@PGFuelInjection]

Sorry, Aaron McGraw I am unable to reply directly to you. I would recommend installing the filter between the stock unit and the high pressure fuel pump as there is a rubber house in this location that makes things easier. Obviously you will need a bracket or other means of mounting the filter assembly and then just two lengths of house to tee into the supply line. There are many kits you can find online to get an idea. Now if you are running any type of performance produces on your truck, suck as a tuner, you will want to look at a FASS system to keep up with the demand while also offering the 3 micron filtration in one unit.

[@bighunterman77]

I've rebuilt a many that get that lil skip and hesitate to crank...To me, that's the sound of hundred dollar bills...haha... But, seriously, if you take your ISB 325 somewhere to get rebuilt and they don't recommend checking/replacing the injectors as one of the "extra" things you need to do, take it somewhere else, cause they don't have enough experience working on those engines

I have a 2003 Dodge Ram 2500 HD with a 5.7 Cummins Turbo in it with over 1 million miles on it. It was used to haul cattle and do plowing and still does. It still has the original engine without any repairs done to it, and it still runs perfectly fine

[@PGFuelInjection]

That's good to hear. Good maintenance goes a long way. The engine in this video is very different than what is in your 2003 Dodge.

Thanks PGFuelInjection for the thoughtful video! It's a good one. Hate to see the comment section so riddled with mis-informed/ridiculous comments. But some of us get your point! 👍

[@ShaunDiener]

the first thing I thought was hank hill

[@JeffinTD]

I’ve added a 2 micron gdp kit on mine. Not a guarantee, but I feel it gives you better odds of not loosing an injector.

[@tylerphelps4759]

Black smoke is an inbalance in the fuel to air ratio. It’s basically just more fuel being put in than there should be air coming in if that makes sense. It’s definitely harder on parts in the long run but doesn’t mean they’re failing necessarily.

[@PGFuelInjection]

This is true but an imbalance in fuel delivery between cylinders can be very hard on engine components and cause a failure is a short period of time.

[@bernhard8540]

5 and 6 are the most common cylinders to have issues with because of the heat they deal with constantly and the poor coolant flow to the back section of the cylinders thats why if you have a Cummins of any sort, you should get the coolant bypass kit with the thermostat in it, I know fleece makes one with a thermostat in it. it will equalize the coolant flow to number 5 and 6 cylinders

[@arisbelmatias8242]

doesn't hurt to spray some degreaser lightly and with water nozel hose it down every once in awhile

[@evildog1966]

I'm saying this first hand because it happened to my truck, and your right it was #6 that failed. Happened on the highway, didn't notice until it came down to an idle. By this time the whole crankcase was full of diesel. Luckily it was still under warranty as the bill came to just over 15K rebore, sleeve, new injectors and turbo. These injectors have about 100 000km on them and now I have a code #3 cyl. open injector circuit. Not too impressed with cummins injectors anymore...

[@weedman7775]

My 12v has smoked black scince I bought it off the lot it is still going good with 736 000km

[@PGFuelInjection]

Weedman777 Sorry about the delay in my response. The engine in the video is a ISB 325 and only shares the name and displacement with your engine. What year is your 12 valve Cummins? Some of the older truck may have smoked a small amount. The generation in this video would not have met emissions in 2006 if it did smoke.

[@dkhill27]

+Weedman777 Same here my 96 12 valve shoots a puff if you stand on it and then it goes away once the turbo is lit

[@The4x4manonbroke]

+dkhill27 that's due to the lag between the AFC and boost pressure ... once a 12 valve builds boost 3-5psi .. it should begin to.clear up quickly .. If not.u may.need to.have your AFC unit tuned or possibly a Injection pump retimed as they sometimes slip timing

[@PowerStrokeLover73]

+PGFuelInjection My Dad owned a 2005 Cummins 5.9L 325hp that never developed this issue, but it still would blow a puff of smoke on acceleration then clear up after the turbo spooled. Never did have any problems with it.

[@PGFuelInjection]

+Brian Robertson Black smoke can be the symptom of several issues. This video only addresses one of these. In response to the "black smoke is normal" crowd, remember this vehicle would never have been able to pass EPA testing in 2006 with more than a slight haze of smoke. Again depending on the mileage, your fathers truck may just be showing normal wear with age.

[@evildog1966]

My guy, Dealership, described the sequence of events a bit different. The later year 5.9's had a lot of compression ring failures but not because of over fueling. The over fueling occurs because the compression ring fails and the there is a loss of back pressure in the cylinder.

[@PGFuelInjection]

I see his point. When compression is lost in a cylinder the ECM will see a loss of output and increase fuel to that cylinder in an attempt to balance the engine. This only happens at idle though so once off idle, all injector receive the same pulse width. As I state in the video we bench test the injectors out of the engine and find them to be over fueling greatly and usually the worst is cylinders 1 or 6 which have the highest rate of failure. This imbalance can be very damaging to the engine as one cylinder receives more fuel then the others when the truck is underload. The piston ring failure could only cause an injector to over fuel if it physically contacted the injector nozzle and damage it. It really is the chicken and the egg question. To be 100% honest, I am a technician and not an engineer. These are the events that unfold in our shop and the connection we see between the failure and injector wear. I hope this clarified things.

[@kennethmaccourt7393]

air dog or fass will do the trick! it replaces your lift pump and adds more than enough filtration! can't go wrong.

[@steveadams8977]

Kenneth Maccourt is that why people add fass pumps to prevent injectors from failing?

[@pvcarmon1]

buckles resulting in a lack of clamping pressure on the air filter gasget. I have heard this series engine lasting over 275K and destroying the #6 cylinder at only 75k with proper maintenance. Wonder how much the OE air box contribute to premature engine failure. Hopefully it is not too late for your engine hopefully this was helpful.

[@dieselbizkets4271]

LOL no blow by? I bet you get 30 miles per gallon as well!

[@alanack67]

230K on mine no blow bye

[@geoffreyc1027]

I agree with you that having a clean fuel system is very important, especially in a common rail system. However, I don't believe the piston you used in your example was damaged by the over fueling injector. The ring broke and damaged the injector. The blow-by is due to the broke ring. The broke ring was probably due to improper air intake system maintenance allowing dirt intrusion into the engine.

[@PGFuelInjection]

You are correct, in saying that the failure shown in the video could cause damage to the injector nozzle. However, this is not the case and not what is being talked about here. From our observations there was no damage to the injector nozzle and the spray patterns were good. Also the fact that the injector in #6 cylinder is most common to over fuel on engines that have not yet had a ring failure. This tied with the fact that it happens on 325 hp engines with the unique piston design. Yes, dusting of the engine can cause blow by as well but again this is no the case in this example. When the amount of fuel delivered to each cylinder varies it creates excessive heat and stress in the over fueled cylinder. You do not feel this imbalance at idle due to the ECM balancing pulse width. At higher RPMs it cannot be felt as much either. I hope this clears up the purpose of this video. Sorry, if I missed the obvious and did not state in the video that ring failure/cylinder wall damage was the cause of the blow by.

[@Mebob2001]

a little puff is normal in my eyes only when you punch it tho and im talking a very very small amount, if you cant see through it then yes problem haha

[@pvcarmon1]

For whatever it is worth on the subject mater. I made a startling discovery of a fine dust in the the hot side turbo to intercooler ducting on my 2006. I traced it to a leak on the POS OE air box next to the battety side where there are no

[@Cam-pv5hd]

I was told that injectors can not be tested in truck because the mechanical portion of the injector may not be operating as the electronic signal would suggest when scanning pulse. I'm no expert, this is just what i've heard.

[@PGFuelInjection]

There definitely are limitations to diagnosing an injector in the vehicle, especially with the OEM scan tool. The return flow test is also very useful if done properly. We test the injector pulse width with an oscilloscope to see the corrections the ECM is making to each cylinder to balance the engine. This gives us an idea of possible injector delivery issues. The short falls of most in vehicle tests on the 5.9L Cummins, is that they are performed at idle and my miss an issue at another operation condition. While bench testing injectors does give a better over all picture, it does not guarantee to the longevity of the injector. A good way of looking at any test is that a fail proves the part is faulty but a pass does not always mean the part is good.

[@baileymiller546]

Isn't this mostly just because of how the owner takes care of it overtime? I want to get an 07 5.9. I have an 01 5.9 V8 but I'd like to have something more recent also.

[@PGFuelInjection]

It would be worth getting it checked out. Smoke at idle is a bit concerning. An imbalance may show up in a cylinder performance test.

[@mattieice4689]

I appreciate the time you took to make this video, but this truck had over 300,000 miles on it. Even as a 2004 (the earliest year for the 325 HP variant) that comes out to over 30000 miles a year. That is an extreme amount of driving in a short time period. This truck was abused. I would bet against regular air filter, fuel filter and oil filter changes performed on this truck as well. Not many diesel owners understand the importance of regular fuel filter changes. I agree that the 7 micron filter is a joke, but if you change it at least every other oil change, you are decreasing your odds of extreme fuel contamination such as this case Thank you for your time

[@joshmindek4840]

That is in kilometers though. So it has around 205,000 miles.

[@dkhill27]

Matthew Trujillo According to my math on a 8 year old truck that's only 2,135 miles a month. 25,625 a year. That's not extreme use at all

[@mattieice4689]

That's your opinion dk. I have to do alot of driving just to put 13000 miles on my truck a year, let alone 25000, which would almost be double what I drive. That is pretty extreme use. There is a reason why NADA and KBB base light depreciation at 12000 miles...just sayin

[@PGFuelInjection]

Sorry, it took so long to reply. You are correct that improper maintenance can lead to this type of failure, especially on a high mileage engine. However, this is a very common issue on this particular model and generally can happen anywhere between 100,000 to 200,000 KM, depending on fuel quality. When the engines we diagnose are torn down, we examine them with a local machine shop and flow test all the injectors. We have had customers putting on over 100,000 KM a year with replace engine failures do to over fueling injectors. By the time they enter our shop they many be on their second or third engine. The cure was to install a primary 2 micron fuel filter and replace the faulty injectors that were the root cause all along. The main problem, is that normal OEM diagnostics will no show this issue until there is a loss of compression in a cylinder.

[@anthonydaniels7712]

new to the diesel world so it happens to both 12v and 24v because I was looking at 04 5.9 3500 cummins

[@uresti27]

This problem only occurs in dodge chassis. I've never seen a 04-07 Cummins in a medium duty chassis fail. I'm thinking is the injector dodge uses for this application

[@PGFuelInjection]

Yes, this engine in other on highway applications, uses the early injector with eight holes and a more normal spray pattern. In these years of Dodge pickup trucks the injectors have five hole nozzles with a very steep spray pattern and different piston design. I believe this was done for emissions reasons and why this engine does not have an EGR system as found on the Ford 6.0L and GM Duramax.

[@PGFuelInjection]

A good quality filter is key. A 2 micron Donaldson or CAT filter would be a good choice but stay away from will fit filters. Some aftermarket filter companies make one filter to replace multiple micron ratings and may not be adequate.

[@PGFuelInjection]

With a vehicle of this age you may experience some smoke from warn parts such as injectors. Generally these older 12 valve engines were very reliable, though if worked hard with high mileage injectors, they can fail as well. This was more common in the industrial engines of that era than the Dodge trucks but I would recommend replacing injectors if they are original.

Hi, I have a 2007 5.9 liter Dodge with 37000 miles on it. I've changed the oil and fuel filter on it a couple of times.

Are you speaking of the fuel filter or what?

[@keithmask9108]

Yes he is talking about the fuel filter. Filters are measured by microns in their filtration determining how big of particles are allowed through the filter. The stock fuel filter only filters down to 7 microns whereas an Air Dog or FASS lift pump filter down to 2 or 3 microns.

[@keithmask9108]

Also as for your model engine it is the same as the one shown. You should still install a lift pump such as FASS or Air Dog or an inline fuel filter such as a CAT inline fuel filter

Unfortunately, this issue is not common for this truck and would require hands on diagnosis. What is the fuel rail pressure when the issue is occurring? Does it match the desired value?

Kelcey K the vp44 isn't the best injector pump in terms of reliability but there are ways to make it last. Most vp44 failures have been due to the OE Carter lift pump failing and burning out the rotor in the VP because of no fuel delivery that lubricates the rotor. Install a fass or air dog lift pump with an in cab pressure gauge and the VP is good for a long time

Do you guys block off the blow by tube to get the blow by to get that much blow by?

[@PGFuelInjection]

Nope. This video shows what it looks like when you pop the hood and spine off the oil filler. No tools required.

[@Dev_Everything]

Why does your oil pressure go to 760??? What is the units on that?

[@PowerStrokeLover73]

+Dev Everything It's kPa (kilopascal) which is found on the Canadian vehicles. 760 kPa is 110 PSI.

[@babybullsmith001]

You said that it needs a 2 micron filtration.Where do you purchase these micron filters?

[@PGFuelInjection]

You would need to purchase an auxiliary filter assemble as there are no 2 micron filter elements for the stock assemble. A FASS system is one option or a filter kit like we sell which installs a fuel manager into the system.

[@babybullsmith001]

How much is your filter kit and what is the address and phone number.Thanks PS how often do you change the filter and how much and can they be purchase by you.

[@PGFuelInjection]

James Smith We sell a kit for about $190 CND. Filters are roughly $24. I would recommend replacing both filters every second oil change or 15,000 km. You can contact us here. www.dieselpro.ca/contact-us.html

[@Northernredneck125]

were are you guys located and what does this test cost?

[@PGFuelInjection]

We are in Prince George, British Columbia, Canada. A standard check up runs about $114.00 CND. For our address visit: www.dieselpro.ca/contact-us.html

My truck is consume a fairly large amount of oil, and I have done every conceivable test on my truck, the only thing I havent done is a test like yours, or a compression test. Ive checked coolant for oil, I have done the oil filler cap check, I have checked both the hot and cold side of the turbo for oil, theres no smoke whatsoever, and my truck has no cat on it to catch smoke/oil. It starts perfectly and runs smooth enough to balance a nickle on its side on the valve cover, I've also checked the blowby tube, hot or cold I dont see any smoke. The only oil leak I have is my front crank seal. It will go from full to add in about 800km or so. I'm not sure what to do, at this point and it doesnt seem like the crank seal is leaking bad enough for me to be losing that much oil. If you could offer a suggestion, I would really appreciate it. Thanks

[@PGFuelInjection]

I would expect some amount of blue smoke if you engine was consuming the oil. You can never over look an external leak. It may only leak while driving or at a specific temperature. I would correct the leak first.

[@Dexter_Solid]

PGFuelInjection Alrighty, thank you.

[@TheAfricanCowboy]

Just a quick question... Are the CP3 pumps affected by this in any way? I just rebuilt my 04 Cummins and had cylinders 1 and 6 look exactly as you shown.

[@PGFuelInjection]

+Jacques De Villiers The CP3 pumps on this engine are quite robust and have a low failure rate. That being said, added filteration will help with longevity.

[@TheAfricanCowboy]

+PGFuelInjection Thanks! I added a fass fuel pump/filter to my truck.

Wait Prince George? Like Prince George British Columbia?

[@PGFuelInjection]

Yes

Wow I have never seen a 6 cylinder Cummins.... Must be gutless. I have owned 5 or 6 V8 cylinder cummins diesels

[@BigBadJohnDiesel]

Does running an additive like Diesel Kleen or Stenodyne help?

[@PGFuelInjection]

+TheFordguy72 Running Stanadyne will help prevent asphaltene drop out, lubrication and moisture in the fuel but will not help with the poor filtration of these trucks. The fuel system on a 2015 Dodge 6.7L is very similar to that on this 5.9L but Chrysler effectively have 3 filters on the new trucks.

[@bigtrucktc]

What software were you using?

In the video I am using a Picoscope. www.picoauto.com

Can you go to my channel and listen to my truck think it has a bad piston, I really need help its knocking and I had the granny built and they said it wasn't the flex plate, and I have new injectors, please help!
