To anyone questioning what was done: It was the cam shaft adjuster and the bolt that holds it to the camshaft. The chain tensioner may have been replaced for good measure. See: Goat Garage video about M276.9 engine rattle on start up.
Is it okey to ride with it or should we go directly to the shop?
@@FCF27 Once the oil pressure has built up, it should run and drive as normal.
The real "oh shit" with this part failing is that the car will eventually fail to start because the timing can't be set correctly due to wear in the components of this part. * I think. *
I'm not a mechanic, but have dealt with this problem on the left side intake cam shaft.
It's really easy to fix it once you know what the problem is, which adjuster it is, and grab yourself a few torx bits and torque specs.
This video was the best explanation I found on YT: czcams.com/video/5Xw2MI4fBIM/video.html
It can be know witch cam shaft ajuster have a problem before unmonting ?
@@ckmckc Yes, take off the small covers in the front of the engine and slowly turn the crank. The one spitting oil and/or where the center doesn't move w/ the outer until "click" - it does.
@@bm-rf4bc how do I do the marking I don't understand, you have to count between the two adjust?
Using synthetic in my M-B, I've never pushed an oil/filter change beyond 5,000 miles (8,046km). Overkill? Yes, but the car now has 256,000 miles (411.9921km) and doesn't use oil between changes, my money spent on expendables.
Changing the oil regularly is the single most important maintenance item. It makes EVERYTHING else easy.
250k miles on a M276 twin turbo?
Does this really make a difference? Have this happening on my 2013 ML350 if I don’t drive it at least every 3 days
What oil are using ? Please
What car
Considering that MB used to make bulletproof motors like the M112/M113 it's sad to see the modern motors so fragile. Even the M272/M273 seem way more durable than the newer offerings. It also doesn't help that MB has 15k mile oil services, I feel like a lot of engine problems surrounding the timing chain, oiling system and top end problems can be prevented with changing the oil every 5k-7k miles.
Planned obsolescence... Sadly our generation won't get more durable items in real life... Everyone is making inferior products
My m276dela30 mercedes got oil changes every 7000 km for the almost 90.000km it has beeing a stage 3 build(550hp),if you take care of them,they are fantastic engines,its because of fools that change oil every 20k km that this engines fail prematurely
@@adriigonzaalez1788 Well the owners are following the recommended interval. MB should drop the interval then so the masses know when to change oil. I personally would change oil more often but given that the oil change intervals were the same in the previous generation motors they never experienced any issues like the newer ones. This is partly a build quality issue.
@@IKhanNot I completely agree. I have seen a lot of m112/m113 and m272/m273s. They are good engines. The m276/m278 are overcomplicated and not as well built.
Well, oil change interval depend on how much fuel you burn. If you're driving in busy city traffic, by the time you'll drive 5k miles you'll burn as much fuel as if you were driving on highway for 10k miles (the numbers are approximate but you get the point). So there's literally no way around this and no "super modern synthetic oil" will help to decrease that interval. So yeah, regular oil changes every 5-7k won't prevent a badly design engine from falling, but at least it won't make the situation worse.
I love to see clean work, well done 👍
Timing chain tensioner?
both sprocket and chain tensioner
Tensioner for good measure but cam shaft adjuster is the cause of the noise. They're spring loaded on this engine so the metal pin causing the racket cannot be simply replaced and the unit reassembled as Tasos mentioned in one of his videos about the subject and seconded by my home-mechanic experimentation when doing the repair.
A failed hydraulic cam phaser? How did you diagnose the problem? Really by ear??
It's that engine's weakness...
I assume they got same problem when they try to fix this car like normal problem on audi and Volkswagen (speed sensor)
@@TiagoVieira timing chain...
@@berendtwohl-bruhn4668 yes...?
chain tensioner
How about chain tensioner check valve installation?
Great. Would you have a link to detailed instructions on how to do this? Greetings from New England.
All the torque specs must be at gutentight, otherwise it’s your everyday timing chain tensioner
@@anthonyshahbazian He didn't replace the tensioner...
I get a similar sound on my 2014 e class coupe on start up. It only happens when I restart the car after around half an hour after a drive. Finding it difficult to get this diagnosed however. It’s a petrol v6 engine
I have the exact same car, exact same issue. What's the mileage on yours? Mine is at 117k miles. Were you able to fix or diagnose the issue by any chance?
@@sinakalantar3968 hi my mileage is 77.5K. It’s still occurring and I’ve not yet had it diagnosed. Any ideas what it could be?
@@rajpanesar2001 I am not sure honestly. I will be taking my car for A2 service soon. I will ask them to take a look.
@@sinakalantar3968 I have the exact same problem, do you find out was wrong?
@@victorr-thomsen5849 Thankfully, mine was coming from a loosened-up oil stick, and it was not the engine making the noise. They replaced the stick and the noise is gone now.
hello show us the garage and the mechanical tools

Super mecanik
in this video did he only repair the timing chain tensioner?
Sangat bermanfaat
What is the size of the Torx bit for removal of the phaser? What is the torque to install it?
It’s like a t100 with a hole in the middle, and if I remember correctly it was torqued to 100ft lbs.
T60 and 120ft
T10 if I'm not mistaken
Thank yoo
1:00 he spins the crank BACKWARDS , isnt this damaging to head?
Oil pump ?
师傅 请问m276.8发动机延迟启动 换了副厂改进链轮还是延迟启动 是副厂件的问题 还是因为凸轮轴信号盘移位了? 谢谢

Hey steve. Great video. Just wanna correct your english in the video title. How to correctly say it is abnormal ASS sound. Thanks for the video!!!
How much for service
Timing chain is still stretched
It was never stretched.
I have m276 motor in my c class. Sometimes it makes that sound when starting the car. Could someone tell what part they fixed and much it costs around?
That's the timing chain hydraulic tensioner.
the part name is cam phaser.
First step would be scan for codes(see if there are any related to timing- looking for failed cam phaser if none, install check valves), Install anti drain back check valves in the passages that supply oil to the timing chain tensioner, MB had a TSB on it, along with new tensioners. If the issue persist, the most likely culprit is the cam phaser(very common problem as those engines aged), There are 4, $1000 each, plus timing chain, components, labor, at least $5,000 at a mechanic. You can always try to fix only one phaser, or find a used one and take your luck on it. None the less, it will be expensive.
Are you talking about c400? I have a sane issue, some rattling at warm engine after sitting for an hour. I replaced both check valves and tensioners but no luck, were you able to address this issue?
@@nashidpeyvast3848 W204 C350
silicone was applied incorrectly and the screws have to be replaced because they are made of aluminum. we don't need to talk about scratching on sealing surfaces...
Ваноси стучали так как износ и потеря давление масло но в таком случи лучше заменить ещё комплект цепи грм если пробег выше 150000км мы в России Ремонтируем эти ваноси
А что он менял в этом видео ? Можешь подсказать ?!
In which cars is this engine ? Is it on the w205 c400?
I have a same problem with my c400
Герметика больше чем майонеза в оливье.
Torque specs please
Actually, this is totally normal for a Benz.
Any problems letting the sound continue long term?
hey, this was troll comment I made two years ago. hope you're car is fine@@wvtrumpet
How much does this repair cost at an independent shop these days?
Hey buddy,
I bought a part from Amazon with 5 years of warranty for $130 and my mechanic replaced it for $350. It takes about an hour problem is intake cam Adjuster, freaking stealership quoted me $5k🤣🤣🤣
@Jey Pam in your dreams this takes an hour 😆🤣😂😹
@@precisionbay6899doesn't look that complicated. How long do you think it takes?
👏👏👏
Still making noise!
Scotty Kilmer always says never buy Mercedes-Benz and BMW that pile of junk
Anything other than a '97 Corolla is junk to that turd.
Mercedes Engine getting every year more worst.
