Josh you're the man! Lots of DMax RU-vidrs out there but their channels are mostly about trying to entertain us with their day-to-day lives and pumping their merch. You create the perfect mix of entertainment, merchandise and REAL information and education about our trucks. I enjoy watching you work on your truck, showing us the do's and the dont's and the mistakes that you've made as well. I follow a handful of guys but you are #1 on my list buddy! 👍
By mistakes of course I mean the pitfalls and situations we can run into, and those things that you wish you had done differently sometimes. You keep it real world. Most of these guys on RU-vid don't even work on their own trucks and when they do they edit everything out to be nice and smooth which is not reality in most cases. You rock brotha! Oh... also trying to keep the wife comments to a minimum so as not to be creepy Lol. But, WOW.... 😁
Thanks a ton! I definitely post normal day to day videos and take about my decals but I definitely keep most videos informative thanks again for the feedback 👍
Yup good point! Anyone know how to contact Josh though? From what I see he doesn’t have an Instagram anymore. And I’ve left several comments 😬. None the less keep up the good work!
Everyone evidently wants to take advanced diesel injection diagnostic advise, Not from Bosch or a GM tsb, but from a guy in a un-finished home garage with a handheld AutoZone code reader 🤔 Seems legit
Mine developed the typing tick after my last oil change, so I went on my diesel truck forum and posed the question lots of answers but the one that was most common was "do nothing after about a thousand miles it will go away or quiet enough that you can't hear it". and that was the best advice because it came out to be true after about a thousand miles I didn't hear it anymore. So with my lastest oil change, its back, I guess I'll be annoyed for another thousand miles...
GM has a service bulletin out on this it’s commonly known as a “type writer tick” here’s a little tid-bit explaining that the noise is resonated from the crank journal bearings. Although injector ticking is an issue the issue you’re hearing is from your oiling system and engine vibrations/harmonics. “This noise is caused by the relationship of the engine cylinder block, crankshaft journals, bearing inserts and the oil film. This relationship may allow a vibration that resonates through the cylinder block and is heard as a metallic ticking noise. The noise could be described as an irregular ticking or clacking sound, like random typing on a mechanical typewriter. This condition has been present in diesel engines produced for the last 20 or more years. The overall noise reduction in engines produced today makes this noise seem new when, in fact, it was masked by other noises in the past. Many manufacturers such as Isuzu, Hino, Mitsubishi, and Nissan report a similar condition in their diesel engines. Testing and engine teardowns with this condition reveal no condition that would affect reliability or durability of this engine.”
And certain brands of oil will make the tick louder and smow make is quiter, and it most of the time comes from the passenger side, according to dmax forms , just live with it
This is pretty helpful and a huge relief, my lmm has recently started to tick but it was after I changed the oil today. It makes sense that that it is the oil and that there could be some air in that synthetic oil making that tick. The tick goes away in my truck after it has warmed up. Thanks again for the info definitely helped a lot
Ive got an LBZ with the type writer tick. When I first got the truck I was running Rotella in it and the tick would stick around for about 1,500 miles after an oil change. I switched to amsoil 15W-40 Marine and Heavy Duty Diesel Oil. I rarely get the type writer tick anymore after oil changes and my amsoil dealer was explaining to me the Marine oil is cheaper and has better engine benefits because it doesn't have to comply with all road laws. Don't quote me on that, its what my amsoil dealer was trying to explain to me and it made since to me so I listened to him. Do your own research.
Love watching the videos this is the first Duramax I've owned, 05 lly crew cab clean no rust under 300k miles and I'm trying to do a full build and you've helped with alot of at home mechanics and just re newing and refreshing of my truck 🤟🏼
I read that a lot of people fixed the ticking by switching their oil. Some switched to conventional to fix some switch to synthetic to fix. Just a thought
It’s me agin Shannon the one swapping the lml. Well just put it all back together yesterday and driving about 200 miles today for work. Low and behold I got that exact sound now and I was thinking crap I just put this engine in. Well the little unplugging truck just confirmed I have a bad injector. Much better than a whole other engine. I was so pissed when I heard the noise today. I’m going to snag one of the old injectors off the old engine and replace the one that quit tapping when Unhooked.
Truck Master you do a great job with your channel. Love your content. FYI I have been using Hot Shot Secret (EDT, Everyday Diesel Treatment) for about a year now and love it. I have a 2016 Silverado 3500HD with a LML and Regeneration Cycles have been reduced by 60%. Also MPG has increased by about .5 to 1 mpg. If you are starting out using it now you should first use their Diesel Extreme first then once you have run that then start using their EDT formula.......I have a lot of confidence in their products!
That noise bothered me with my lbz and then I read that same bulletin. However I did start running amsoil synthetic and now I don’t notice it near as much. Great video!
I got the tick immediately after switching to Amsoil. If you use it, don't expect your noise go away. I used Delo before and didn't have any noises ever. I'm going dump it and try Schaeffer's synshield. I know a guy who had this issue with a few Fords. Schaeffer's immediately stopped the ticking on both trucks. If that doesn't work, it's back to the big box of Delo at Costco.
I bought my LLY in 2010 with 73 thousand miles. I started using at purchase the Amsoil 15/40 full synthetic and every other fill up a small bottle of Marvel Mystery Oil in my fuel. Never had a tick. Knock on wood. LOL.
Nailed it. Oil is huge. I have had 2 duramaxs one lb7 and an lbz both click… harmless. The less u listen to the clicks the better. I have put 200000 miles on both trucks. When they stop fixem otherwise drive em. 😅
Just FYI, all Duramax 6.6 engines have a tick or "typewriter" ticking noise. It comes from the crank journals, usually at lower to mid rpm. There are GM service bulletins that explain this. Changing oil brand and or viscosity can quiet this some, which may be what you are experiencing with the Hot Shots oil treatment. There is no "FIX" for the Duramax tick.
@truckmaster I have the typewriter noise on my truck but it actually went away for a while but after I changed the oil and got new tunes it started doing it again when I first bought I started using Mobile 1 delvac and that made it go away anyways keep up the good work been following you for while now ✌️
Quick tip from an Old Wrench for finding exhaust leaks: !!REMEMBER, SAFETY FIRST. USE YOUR BURN RESISTANT SHOP GLOVES!! Wet down several shop towels that have been rolled together and grab them with long nose or vise grip pliers. With the engine running, carefully press the wet towels against the area of the exhaust manifold or pipes that you think may be leaking. If your suspect area IS leaking, the towels will quiet it down until you pull them away. BE CAREFUL. This is a trick I used to find exhaust leaks, and yes, I burned hands and arms while doing it. If this manner of diagnosis is beyond your comfort zone then don't do it. Skin melts fast!
I use Schaffer’s oil now couldn’t afford amsoil anymore plus what sold me on Schaeffers oil, was the RU-vid videos on engine tear downs. Motors with a million miles on them and all they use is Schaeffer s I use TOTAL POWER additive in my truck every fill up and POLAR POWER for extreme cold. They both come in a quart bottles and treat 250 gallons.
My '05 LLY i bought in '15 sounded like someone hitting the firewall by #8 with a hammer!lol Started using Rotella T6 5w40 and also had a Pcv Reroute when i bought it, hooked it back up stock and tick went away. It also had an egr blocker plate last summer when i took the cooler off and intake pipe the Y Bridge was spotless no buildup from pcv mist after 3 years hooked up. And no more annoying vapor trail at night behind me..lol
Great video, very informative! But that quiet looping piano music in the background -- I kept thinking there was an ice cream truck coming down my street
My Cummins had an annoying tick and I was using rotella t-6 switched to amsoil 5w 40 and it’s a lot more quiet. I also used amsoil engine flush before switching to amsoil.
Good info thanks as always. Also I’m sure you know but when you you get ready to change your Fass filters they have new style ones which are short and more efficient. Installing mine next week..
Also not sure if you have a gauge on your Fass but if you have not replaced the regulator on the return in your Fass I can almost Guarantee that it fluctuates there is a new updated regulator and spring that they will send you for free . After replacing with the new one it is solid. Before it would bounce 2-4 psi .I have an email contact if you need it.
Mine does typewriter tick with t6. But I know that oil is tried and true. It's just an annoyance its not hurting anything and it's totally random. Still good info and good.vid
GM released a bulletin on that stating that it is a result of the Duramax's natural acoustical occurrences within the engines manufacturing tolerances and design of the engine block... something to that effect...I interpreted it to mean that it's supposed to sound like that! lololololol 🤣
My noise just started a 400 mile trip. It increases with acceleration. No power loss. I have an airdog but still have the engine fuel filter, which has a small diesel leak. Not sure if it's that or a exhaust manifold leak. Injectors are new only 10k on them.
Try Enerburn. It's a fuel additive. 1 OZ for every 75 liters of fuel. It really works for eliminating any carbon deposits by making the fuel burn complete. It is formulated for engines with EGR systems, but having no carbon coming out of the valves reduces carbon knock. I've tested this for hundreds of thousands of miles. It really works. I've never had to force a burn.
And honestly you have to figure out what oil works best for you, they're guys that say they use rotella developed the tick, went back to Valvoline and it went away. It seems that Duramax are so temperamental and have such a unique personality we have to figure out what's best for our trucks.
I had the same issue in my LBZ, the tick sucks when your at a stop light and your trucks making that horrible noise. I switched to Amsoil and I rarely ever get the type writer tick anymore. If I do get the tick, it only last for 30 miles or less, usually after the first drive.
kyle parker no tick here, I've run Shaeffers exclusively, after 20k mi. with Dyno oil for break-in purposes. I actually seen a drop in engine temp when I started running it. Less friction= less heat
And I’ve been driving myself nuts because I got my head gaskets done and they used a different oil. Guess that made the ticking louder so my heads have been off three times now thinking it was a loose rocker. Just changed my oil back to the royal purple I always use we’ll see if it goes away now
They say in their TSB it's oil cavitation/flashing, and is not detrimental to the engine. My Mustang 5.0L Coyote engine has that typewriter tick as well.
My tick came after my oil change too. Huh...wonder what caused it. I add oil stabilizer and it goes away for a bit...but does come back. I blow more black smoke now too.
Had the ticking in my 06 Duramax. It started after I filled up with diesel. Added Howes fuel treatment and it cleared up. Happens more in the winter with the winter blended fuel. My truck is deleted and it seems it's very picky with fuel.
You should try arch oil friction modifier. They also have great fuel additives. My brother is saving 40L per day on him semi truck by using the fuel additives. I use the arch oil in my 6.0 ford and it give me 3-4 mpg plus runs much better.
Thanks for the explanation. I don’t have quite the tick going but interesting to hear some explication for the noise. Running Rotella T-6 and sometimes put in the fuel Diesel Clean.
I have an 07 lbz and an 18 l5p, both of them do it. Bought both of them brand new and both ticked from the dealership. If you get under the truck it sounds like its coming from the flywheel. Ive taken the lbz to the dealership when it was new and they acted dumb, like they couldnt hear it. It hasnt caused any problems in either truck though.
Off subject! Oil pressure goes to nothing on gauge and goes up with rpm’s. Changed sensor. Cold oil pressure is good and gets worse with hotter oil. What do I need to change or do. I love the Duramax but I hate how close the gauge gets to the red. They need to change this
I could be completely wrong it’s tough to say but do some research on symptoms of a faulty oil pump. That might be your problem. But it’s hard to know until someone looks at your truck in person.
I could not find the bad injector using 3 different diesel mechanics. I ran a full bottle of diesel Kleen and a bottle of transmission fluid in the gas tank and it runs perfect. It’s sad we live in a time that people in service don’t know what they’re doing. In this case mechanics suck bad. They give up way too soon and if the computer can’t tell them they don’t know how to figure it out.
I was sure I had a bad injector or lifter on the driver side but today I found out it was coming from my a/c compressor. Turn it all the way off. Check it out I can't be the only one.
Hotshots is the bomb ass additive. for the first dose use the extreme in a tankfull then switch to the EDT. Also using the stiction eliminator in motor oil and transmission. quieted both down and makes the motor quieter I've noticed.
I have an LMM duramax and I changed the oil, I went from 5w40 to a 15w40 and it started ticking. What’s your thoughts? Also so thankful you made this video 👍🏼
Can you explain how to get to that section in the scan tool? I have read the manual and searched online, but cannot find any information on how to perform this.
I'm not sure guys so please correct me if I'm wrong but, I think stiction is only a problem for engines like the 6.0 and earlier powerstroke that used high pressure oil to fire the injectors.
Often your ticks or valve noise will go away running conventional oil. More likely to have a tick with synthetic, as its typically thinner dispite weight ratings.
its got to be ticking for a reasonIf you have a starting problem after it’s the flex plate where the trans and motor meet. Same this with my HD gasser. Fixed the problem not runs so quite sounds like electric truck, or the lifters
Hey Boss. I have an 04 LLY with a new long block, all new injectors, new turbo, and no codes. Running 15w40 synthetic. Truck is getting horrible fuel economy and has the ticking sound only under a load or driving around 75mph... Taking it to the shop tomorrow morning. What should I look out for? Love your channel!! Thank you for your service!! Semper Fi!!! 🇺🇸
I had that same ticking noise all it was, was the injector barely loose and It was misfiring out of it pulled the injector out clean it put new copper washer and O-ring put it back in solving the problems if you look around the injector and see black that’s the signs of it misfiring out of it
Once again, great info. Will the Edge CTS2 Monitor give you the same injector readings? I'll be looking forward to your opinion on the Amsoil and a good fuel treatment. But if you do the Amsoil and the fuel treatment at the same time how will you know which one fixed the ticking?
What about a chirping sound sounds stupid but thats the only way I could describe it , coming from the back or bottom of the motor and it comes and goes not always there completely stock?
Do you have to pay for subscription renewal with this scan tool? I was looking into the launch x-431 pro, but you have to pay to renew for various functions after a while, which seems ridiculous to me.
Hi I have a brand new 2022 HD AT4 with excessive ticking this is a good topic to talk about . This would be a good topic to go over with the community mine just got the transmission pulled to check on the fly will be installed a new fly wheel and torque converter mind you my truck at 6000 miles on it they have the GM rep coming out next week?. That's not only thing that's going on with it at deceleration coming to a stop sign it sounds like the taking is turned into a loud knock like an injector or something is about ready to hand grenade I don't know what's going on really disappointing. Let me know if you have any ideals. Thank you for your time and a great videos
