In case you’re wondering this can be done on an m278 but plan on replacing the top chain guide. It pops in the under side of the valve cover. And when you compress the timing chain tensioner compress it slowly. Better to replace it to be on the safe side. Hardest part is getting the camshaft adjuster on with the chain in place.
Not bad. No liquid sealant goes on the cam solenoids though, they are O-ring sealed.
Недавно делал такую работу . Оказывается не я один такой в этом мире правда делал первый раз ушло 3 часа но это лучшее чем разбирать пол двигателя . Ребятам респект за то что не обманвают людей . Кстати также можно цепь поменять без снятия распредвалов
Thank you so much for filming this!
Thanks you just save a few people atleast 3 to $4000 minimun. I really appreciate it
totally agree, in my area clown mechanics want for this $2K only for the labor.
what was the reason for doing this? rattling sounds when starting a cold engine maybe?
Looking to do this with a m276 adjustor locking tool from aliexpress. Ive done tensioners and check valves before but now i need to replace left intake adjustor sprocket, any pointers or tips anyone can provide would be super helpful. Thanks!
at 0.13. which crankshaft position he rotate to set the timing mark. Is it at 40? how does he pull out the adjuster when the chain is so tight even with tensioner removed?
what a professional work. i need to replace VVT on my W205, so i can just unscrew that VVT and replace with new VVT without removing chain tensional? pls. advise. thank you in advance...
The master ❤🙌💯💯 thanks for the video
If it only takes an hour to compete why does it cost 4-5k to repair
In the video at the end, the car still had the rattling noise. Was this video taken after the repair or before the repair?
The rattling was due to an oil change. Once the oil in the system circulated and pressured up, they shut it of and re-started it. Notice the sound did not occur on the second startup.
@@CORZER0 nope its should not sound like that once u change to correct VVT.
@@seeingit9337 central valves (the bolt holding the adjuster) have to build oil pressure which is why you're supposed to soak them in oil
@@seeingit9337 It just needed oil pressure to fill the large volume that was empty and would stay filled with oil during normal shutdowns
@@CORZER0 Still shouldn't pop out if it's locked. Mine has only done it once and never again. Still have code though. And I have blue bolts indicating service has been done.
How did you lock the camshaft without removing the valve cover?
Million dollar question. Still unanswered.
@@GunnyNinja It would be vary dependent on crank angle and that would change with each camshaft. Luck? The back of each camshaft is accessible though with the cam plug removed
Also there is a tool available online to lock the back of any M272 camshaft. Tight clearance too
@@bicylindrico Only on one side. Pump blocks other side. But this video doesn't show using the plug.
I believe number one piston top dead center, then rotate to 40 degree mark. Intake should be relaxed in that position.
This p001685 ?

This may make another problem. Why tmhe didnt check cam shaft damage?
What is lock camshaft ??
Nice video. Where are you located please?
easy work 😊
I have now subscribed to your channel
What the noise ticking after starting is it timing chain ?
That’s the cam phaser building oil pressure, once it builds oil pressure it goes away. That’s why when he starts it the second time, it is quiet.
I have same problem can you do it for me what is your location
What’s the socket you used to remove the adjuster
T100
Good
Somebody in the netherlands that does this?
This is a very good video, but for me as an amateur it would've been even better if you explained what you're doing step by step
This videos is for technicians mostly. I know every step that he did, and it was quite helpful.
@@BeardMan01 I'm a DIY but I'm wondering if it's worth holding the crack case while loosening the bolt
@@jeremyocampo1529 holding what?
Hi there 👋🏼😊
What size Torque Socket you used?
Special socket a T-60 but its hollowed out in the middle. Search google for m276 cam tool and you'll see it.
T100 socket.. 130nm tightening torque
This is 25 cents question. You need 2plug tools. I did several times, and prices from $1000 to 1500.in one hour, is good money.
师傅好 我的276.8发动机有延迟启动 修理厂给我换了右边的副厂升级链轮 车拿回来了还是一样延迟启动 请问这是因为配件不是奔驰原厂的问题 还是因为凸轮轴信号盘位移要换新的可是他们没换?
凸轮轴信号盘要調
So you can make your own marks and not have to turn engine to release pressure on the chain just like Mercedes says to use their lines not mark own??? Let me know
Yes. Count how many spaces between gears, from gear to gear. make sure its the same when you replace.
The logic is that you mark the camshaft adjuster and camshaft reluctor wheel against the block. You do this to put everything exactly where it was. If you do this, your timing will be exactly as it should be.
so the cam adjuster laser marks not lining up with two yellow chain marks is ok?
@@fredchiang7139 The engine should be at 40 deg past TDC, and actually, those small cam adjustets would spin multiple times before the long chain would rotate once... So there would have to be markings every few inches all around the chain in order to ensure that the marks all lined up at each adjuster revolution... Or you might have to turn the engine dozens of times to get the marks aligned... But you DONT have to do this. When the engine is at 40 degrees pass t d c... The camshafts are in their maintenance position... At this time, you mark an overlapping spot on the chain and the adjuster, and also against the block/adjuster and against the reluctor wheel/block... This is actually overkill, as only the chain VS the adjuster is actually all That's needed, but In this case overkill gives you diy'er redundancy.. So you transfer the adjuster marks and put the new adjuster back in that exact same spot. Think about it. Logically, the engine is now exactly where it was before you started the work...
@edwincolon7782 there is more to it... image if you rotated the camshaft and adjuster 180 degrees on one bank... or maybe didn't notice a 10-degree rotation.. and then simply counted perfectly "accurately" the chain spaces between the adjuster .. you coild destroy the engine instantly.. or with the small accidental rotation, have a very rough running engine.
SO,
You will get the spacing you describe automatically by placing an alignment mark on the chain and adjuster for each bank.. transfer the mark, and when you place the new adjuster on the corrosponding chain mark, you get the spacing you mentioned, and equally important, you get the camshaft back in the exact same spot as you started...
Its still ticking... LOL. Its not supposed to tick like that.
Can u explain steps to me please
What is torque lbs. for the cam
130 nm
😂yeah i think mine need replace too. Engine sounds so loud like your video at end, and restart doesnt work😅
Someone who wants to help me out, ill pay for online help.
Anyone know where the timing marks should be for that bank so I can change my tensioner with the chain slack.
I believe its 53 degrees to check your camshafts are in the right location through those four eye holes and then turn it to 40 degrees for max slack for removal of the cam adjusters
@@ymxjack Going from 53 to 40 do I turn the crankshaft back / anticlockwise or clockwise. If its clockwise it would defete the object of golng to 53 degrees in the first place.
Jeff
@@jeffrobbins2318From memory I think the manual said dont reverse turn the crank (counter clockwise) plus you're only checking that the signal plate indicators of the camshafts are all dead centre by turning it to 53, if any of those aint then you know the misaligned camshaft(s) is gone and you need to replace it along with new adjusters. After checking I would just turn the crank clockwise until you reach 40, lock it in place and begin ripping it apart. Thats just my understanding anyways
@@ymxjack I don't want to touch the adjusters I just want to upgrade the secondary chain tensioners.

I wish you were in the UK I am having a right nightmare finding someone to do this on my car
I recommend doing it by yourself.
Did u find some1 ? I'm in same boat 🤣 thinking of having a go myself would be good if I didn't need to remove valve cover
@@danieloreilly7028 I used Wayne gates in Harrow. Highly recommended 👍
@@ChrisUnitt82 what was the cost if u don't mind me asking
@@danieloreilly7028 czcams.com/video/dVFfIcrQfus/video.html
😂 this BS your camshaft will spin 100 pounds of forces WTF
Not if you hold down the crank
