Pinging noise in '07 5.9

[Tretola]

I have an '07 5. 9 6 speed with 300 miles on it. It seems to be making a pinging noise under acceleration between 1500 and 2200 rpm in each gear. Before I bring the truck to the dealer I was wondering if anyone had any suggestions. This noise may be normal I previously had a '98 12 valve were you couldn't hear anything but the injector pump.

Welcome to the world of ticks, pings and knocks. I have a 2006 QC SB 4x4 with 8,500 miles. I started to notice a "spark knock like" noise in my truck at about 3,000 miles. I have extended a thread on this site for about 3-4 months.



Members have theorized that this noise could be anything from normal to an impending injector meltdown. Nobody REALLY knows what it is caused by. Everyone has a theory on how to cure the noise from using every type of fuel additive available to driving your truck "like you stole it".



I have tried most of the additives and towed a fifth wheel for 5,000 miles at an average of 65-70 mph. I still have this annoying "spark knock" like noise.



I talked to a dealer mechanic who said "I don't know what it is, probably a computer reflash will fix it. " I still don't know if I want someone trying to fix something he is not familiar with by reflashing the computerized controls of an otherwise great running and pulling truck.



For the near term, I have decided to wait and see if this noise gets any worse or better with more miles. There are other ideas and theories available by searching this site for "engine noises".



Good luck. And if you find a definitive answer, please share it with the rest of us.

Chuck

Here is my take on this. My 04. 5 and my 06 don't have any noises but I once read a theory on here that our trucks are so quiet now that we hear more stuff that has already been there. My A/C hummms when the compressor cycles on my 06. I also have an 02 24 V and a 96 12 V. If either of them ever hummed like this one, I woul NEVER EVER hear it over the roar of the engine... If an injector was " TIcking" on the 02, same thing. I would guess that if your not seeing smoke or performance reduction, it might be Ok, but I am far from being a mechanic...

I have a brand new 07 and it has been making the slight ping since I drive it off the lot. I test drove several others and they all did the same thing.



I had an 98. 5 before this one. It made so much racket. These new things are so quiet you can hear these new strange much quieter noises.



I think the sound is perfectly normal. Afterall, it is a Diesel. Don't worry about it. Drive it, and enjoy it.



Best Regards,



Sean

Funny you started this thread. I was going to post the same thing. I have a 2007 Quad Cab Dullie 4X4 5. 9 with a 6 speed stick doing the exact same thing. It's obnoxiously loud at 2200rpm. It is in the Dealership right now. They are trouble shooting it as we speak. It is been getting louder since new. I now have 5,000 miles on it and I cannot live with it any more. The Tech went on a test drive with me and is trippin on it. Says it's the first he has heard this baddddd. Additionally the clutch failed on it in the first 800 miles. Seems there was a factory recal on 1,400 2007 model stick shifts for automatic over adjusting clutch assembly. I drove the truck 4 days and they kept it for 4 weeks waiting on parts. What kills me is I bought a 1998 brand new with a 24 valve 5spd stick and it ran flawless for 150K. I traded it in on this new one 3 months ago, and I have had nothing but trouble. . Sorry did not mean to steal your thread bro. I'm just totally disgusted right now. But I will Guarantee you that if they solve the problem, I will post it for all to see immediately.

14,000 miles on my 07 in the first 2 months. No ticks or problems here. They dont all tick Good luck gettting yours fixed.

 

[APersondek]

while all of the above is mostly true, in terms of what will and will not cure the ping - the fact of the matter is there are multiple injection events taking place (3 that I know of - pre, main, and post) this helps with emissions etc. depending on who you talk to, and how long you have been lurking here - some say the third injection event is what pinging noise is that you hear.



Some will say "buy a Smarty to fix it - still others will say buy XYZ additive and programmer to fix it" I say the engineers at Cummins know what they are doing and if it happens to melt down - and you have been maintaining it correctly (oil, oil filter and fuel filter changes) per MFG recommendations then it will be warranted. Know I have a '04 with 305 HP and only two injection events so I don't have worry about any pinging - so to speak of and all of the above is just my two cents worth..... take it for what it is or leave it

 

[betterthanstock]

If all 6 cylinders tick, you're fine. If one stands out, and it has a ra-tat-tat to it as you accelerate, then it's one injector that is not opening or closing quickly enough, and may be fixed by additives, or it may get worse until it burns a hole thru a piston (if it gets stuck open).

It's hard to diagnose a noise based on someone else's description, so take it to a Cummins shop if your dealer is incompetent, and if, in your opinion, it sounds different than other trucks at the dealer.

06' Quad LB..... quiet for the first 6000 miles, then tick,tick,tick... ... could it be the new fuel and the lack of lubricity. PS-S seems to help alot.

Hey Guys: I went back to a diferent dealer just to drive a few more to set my mind at ease. It Did not. In fact after driving 3 new 2007 with the 5. 9 I found no Ticking noise in any of them. With this, I am now at a total loss as to why some do and some don't. My opinion at this point is it should not if others don't. I like the idea of taking it to a Cummins Dealer. If my Auto Dealer cannot resolve it, then that will be my next step. APersonDek, While I am very meticulous with my services and documentation, I feel it unacceptable to wait until a piston melts down. It would be my luck it would happen while I was on one of my 9 hour trips to northern California to go Salmon fishing while Towing my 21 foot Striper. My new truck has already left me walking on the 4th day of ownership due to a poorly engineered failed clutch. My 98 QuadCab 4X4 5spd Turbo Never made me walk for 150K. I am still a Huge Mopar fan and have built alot of high horse power Cuda's, Coronets, belveders etc and currently looking at challenger with a 440 6 pack to buy and restore. I have been a member of TDR since 1998 when I bought my first Dodge truck. I look forward to each and every issue and read them cover to cover. I have found it to be a great resource for information. I just decided it was time to get on Web Site and start pulsing all of you fellow Dodge Truck Lovers. I can't think of a better place to start looking for good answers to real Problems. At any rate I will be quick to share with you what my dealer does to resolve the Mystery Tick at 2200rpm. Thanx again for all the shared responses guys.

Maybe what I think I hear in my truck and the ones I test drove was different. I would describe it as a slight ping or rattle, at low to medium throttle. It is so slight it is hard to notice with the radio on or the windows down. Does anybody have a sound clip of this "ping" they are hearing?

 

[sag2]

I think your being a little too sensitive. Especially if you came out of a 98. These engines are quiet, and they all have their own personality. All three of mine have made all sorts of strange noises, and they never let me down except when I put in a bad load of fuel in the 06. I guarantee you your 98 made all sorts of noises, but because they did not control the injection events like today, you just couldn't hear them from all the knocking. And yes that 98 knocking was caused by pistons and cylinder walls vibrating from the combustion events, and they lived on for many hundreds of thousands of trouble free miles.

If it was mine I would get it back and drive the pants off it. In all likelihood there is nothing wrong with it, and a little pinging is not going to hurt anything. When something goes wrong with one of these engines you will know it because they will knock like they ran out of oil. Just do a search and you will find very few engines that failed for any reason, especially from some minor noise.

I don't mean to sound harsh, but your just frustrating yourself by letting the dealer try and find a problem that is really insignificant.

The clutch was a known problem and they jumped on the fix for that right away. I only recall a couple of repeat clutch failures, and that was early on in the model year. Also just like your clutch did, they failed right away.

 

[CTRice]

I intend to be one of the avid followers of this thread since I developed the problem at about 3,000 miles and have tried every additive suggested so far with no discernable change in the maddening "Pinging. "



Who ever finds the answer will be a hero to many of us who are concerned with ignoring a noise that would melt down a gas engine or leave us stranded far away from home.



Thanks to all for your efforts.

Hey Guys: got the news on my ride yesterday. On my Clutch that is. Apperantly the 2nd clutch that was put in at 800 miles has now failed at 5K. They are putting in clutch number 3 as we speak. Word is the Springs were loose in the Flywheel. Yes you heard me right. there are springs within the fly wheel on the 07 manual trans trucks. I would love to see the configuration on this. Never the less 2 clutches in 5k miles. The new dealer doing the instal is very reputable, so I am guessing this is the last time I will have to deal with the faulty clutch again. My new fly wheel should be in tomorrow and installed. Next item to be addressed will be the obnoxious pinging. I have every bit of faith in this dealership to resolve this as well. I went through 2 previous dealerships before I was refered to this one that I am dealing with now. What a diference from one dealer to the next. Just glad I finally have a good one and they are fairly close by to. All keep you posted as things develop. Thanx again for all the input guys.

 

[CTRice]

Sorry to hear about your clutch going South for the second time. Glad to hear about your finding a dealer who knows what they are doing.



Please keep us posted on your "pinging noise" resolution. I own one of these pingers also, but have been reluctant to have a dealer "try" this and/or that. There must be a simple answer to this dilemma without resorting to trial and error methods.



I am going to NC this week and will be trying various additives and driving methods to determine if the pinging gets worse, better or stays the same under different conditions. I will post my results on this thread.



Thanks,

Chuck

I'm with you. I cannot believe this pinging noise is normal when I have driven several others that don't ping at all. Trust me, I am Adimit on this issue. I want it resolved period. Living with this noise is straight up Bull $@#T. Some one has to know the answer. I'm gonna get it. I trust these guys to get it and resolve it. What blows me away is the Collective Thesaurus of Knowledge within this TDR including all of their outside contacts and still no FIX. . Either there is some thing definitely wrong, or I am expecting to much. Just seems that Ford & Chevy Run a whole lot quieter. Either way this noise is obnoxious and for what my truck cost, I should not have to put up with a funky noise.

 

[CBrahs]

Mine does the same thing and the dealer told me they won't touch it until i have over 15k miles on it because it would be an "adjustment". I can hear mine at an idle more though.

 

[NJones]

Time was if a diesel didn't sound like its about to fly to pieces somethings was probably wrong with it. They have gotten so quiet I too seem to hear stuff I never heard before.

 

[CTRice]

Hey Guys,



I just drove back to Michigan from NC. I drove the truck harder than I ever have before. When I arrived in NC, the pinging noise was still there but a little quieter than before.



Since I vowed to try more additives this trip, I made up a cocktail of 8oz. of PS White and 8oz. of MMO for one tank of fuel. This concoction quieted the pinging down considerably. After adding this mixture to a second tank of fuel the pinging is nearly gone.



I don't know what the h*** is really going on here, but I would bet that the fuel companies are selling us fuel with little or no lubricity additives. I can think of no other way adding oil to our fuel should quiet down a suspected injector noise that sounds like spark knock. What do all of you think???



For now, I am going to continue adding this cocktail to each tank of fuel and monitor engine noises and performance. I will keep you posted on the results.



I am interested in any other ideas, opinions and experiences any of you may have.



Thanks, Chuck

I had a lot ticking noises too. Last fall I adjusted the valves and things got very quite. About two months ago I had my leaking cp3 replaced by the dealer. Now it is noiser than ever. Go figure!:{
