Mines a 6.6 Duramax and when it’s cold it sounds like a blown motor. When it warms up to around 190 it sounds perfect. I hope it’s just an injector or two. Worried about the motor and the motor is new with only 8,000 miles on it as well as the injectors. I got standard injectors from O’Reillys
Fuel injectors go bad on these trucks every 150 or so. At least for me. Its because of poor fuel quality or DEF (a.k.a government cat piss) but just make sure to get it fixed asap because it can damage the Cat and the engine.
I have a 2011. 2500 doing the same thing except there is a slight chirp in it also. It has 200k miles was driving and pulling excellent. Turned off getting off the highway at a stop light. Wasn’t pulling weight, and no previous symptoms what so ever, out of nowhere at the light started ruff idleling then shuts off.
The General I took it to the shop. They put a new starter in it, it started up but idles very nasty. My motor is shot, I spun a bearing. Fu$!&!)!$$$$$$! Yea so that’s that, I’m hoping insurance covers it.
Ed Gonzalez dang man, sorry to hear all that!! That is a downfall of owning diesels for sure. Everything is expensive. Well, i hope it all works out for you for sure bub. Sorry for my delayed response to you as well. Been trying to get things together for this potential hurricane situation!!
Why don't u use the diagnostic read out n watch what pressures those injectors r at. This could be a computer programing 4 that #6 injector. U will c what pressures at idle n inder load. Good luck.
Well beings yours is not a common rail, im not sure that your issue is the same as mine. Mine was the #6 injector. I changed it, along with the fuel feed tube, and its been good ever since then.
Hey man I know this video was posted a while ago but my 2015 Cummins is making the same noise but it’s has nothing to do with the compressor going on and off, my started doing it on start ups (hot or cold) but would go away after 20 seconds but now it’s way worse (two days later) truck has 108k on it what ended up being the issue with yours?
Mine was #6 injector. You can either send it in and have them eectronicly shut each one off, or you can pull the valve cover off and unplug each one, one at a time and see if it eleminates the noise.
@@shugbe5477 I pulled the cover and checked everyone and 1 and 2 made a slight difference but not enough to say for sure it dosent idle rough but the weird thing is now that it dosent go away at idle if I get to about 1400 rpm it goes completely away
I have an 06 ram 3500 srw. I had the same knock and could not find what was causing it. I was going Cuckoo! it was driving me mad. One day I decided to have another luck underneath and you won't believe what I found. It was a tiny Leprechaun with a tiny sledge hammer banging the side of the block! Caught the f*cker and flushed him down the toilet and the knock went away yeeehaw :D
@@Rocko1983ify i thought mine was in my drivetrain. I changed out my TQ and flexplate, but still had the noise. Ended up being my number 6 injector knocking.

09 6.7 is making the same noise this video saved my life I thought my truck was done with
Awesome man, glad it was some help for you 💪🏻💪🏻
I have the same 09 6.7 started today rough idle and when stop at light takes a while to take back off found out it’s the injector 1.
Does it throw a code
@@jonathannoblim7667 no
Been looking for the cause of this noise for 6-7 years, I hope this is the issue

Ed Gonzalez dang dude, honestly not sure right off what that would be. Mine never actually shut off. Did it ever start back up?

It’s crazy cause it was running excellent pulling fully loaded trailers of dirt and cement. For it to go like that bearing no weight...?? Bummed out.

The General thanks man your video was very teaching.
I have an 06 5.9 started doing it of an on tonight.
mine does not sound that bad. but it has a slight knock. It does have 350k so im going to check it out
Did you figure out what it was
@@scottyfilms9301 from investigating people say its normal. as long as its not excessive. no check engine light or loss of power
Fuel
Dude my truck is making that same noise. 2010 2500 with 128k miles. Gonna check that out thanks
No problem bub.
Did you get it figured out bub?
Did it throw a code?
If it comes and goes with AC on then it’s probably low on Freon... that’s the compressor ticking
2021 and has 72k and making that noise
Why don't u use the diagnostic read out n watch what pressures those injectors r at. This could be a computer programing 4 that #6 injector. U will c what pressures at idle n inder load. Good luck.
i guess Im kinda off topic but do anybody know a good site to stream newly released series online ?
@Frederick Maximiliano try flixzone. Just search on google for it :)
@Emmanuel Francisco yea, been watching on FlixZone for since april myself :D
@Emmanuel Francisco Thank you, I went there and it seems to work =) Appreciate it !
@Frederick Maximiliano glad I could help xD
A/c compressor
Definitely connecting rod
Mine is doing the same thing but it’s a 1999 does it with air off

is this cummins or another
6.7 cummins

Thats how i figured mine out finally lol!!

@@drewhall6511 having the same exact issue with my 2010 right now
What was result?
Blake D #6 injector was bad. Changed the injector and the feed tube, and all has been well ever since

2016 2500, 36000 same noise comes and goes tho
Have you checked injectors yet?
@@shugbe5477 no, never thought injector could be causing the noise. Comes and goes so I had no idea what was going on.
@@Rocko1983ify i thought mine was in my drivetrain. I changed out my TQ and flexplate, but still had the noise. Ended up being my number 6 injector knocking.
Cp3 knock
#6 injector it turns out lol!!
Cp3 knock isn’t that fast, and doesn’t last that long. That’s dead nuts for a 6.7 injector, and it always seems to be #4 or #6
