As a new MB owner, must say LONG LIVE MERCMAN! This is only video on YT where every aspect of problem is presented and addressed, even people without mechanical knowledge can understand! Much respect, tip of the hat!

These damaged camcrafts are a well known problem mostly of Taxi driver who let their OM654 run at idle rpm for several hours every day when they are waiting for guests. I think the oil pressure is a little bit to low for this bad working condition, but Mercedes choose the cheaper solution. OM654 after production date 6/2018 or after 6/2020 (I don't remember the exact date.) use in the rocket instead of the old "Nadellager" a upgraded version, a new "Gleitlager". This OM654 is build in nearly every, version of passanger car AND truck like "Vito" or "Sprinter". With some care and the right maintainance it's no problem to reach more than 500.000 km. Oil change every 25.000 Km is too long. It's better to change every 15.000 Km. The remaining weakness is the timing chain and the "Steuerkettenspanner". With bad maintainance an expensive replacenent after only 150.000 Km is possible.

Another great video, glad to see you back on KZfaq. We get people asking about you on the UK Mbowners club. Keep up the good work.

Great video as always, very helpful!

Great vídeo. Cheers from Portugal

Excellent video, thanks for uploading it.

Great video very well explained 👍👍👍👍

glad you've back, It's been a long break :)

Thanks Mercman for this explicit video, I'll like to know if the problem is likely to reaper once its been sorted.

THANKS VERY USEFUL VIDEO

Great video! Keep it up👍🏻👏🏻

job well done-great video

Could you please provide the part numbers of the 3 Parts? From the rockers, hydraulic tappets and camshaft. Thanks.

Mercedes should own up to the crap rockers they have put in this engine. Hearing of so many failures, I'm amazed they are getting away with not paying to fix this issue via a recall.

Awsome job

Did u remove tensioner to do this. Thanks for the tips

Great video

did you know if in the new version om654m they still have this problem? very upset i tought about to get my first mercedes c o glc because they last a lot but unfortunatelly is not more like this!

thanks for sharing bro

Ola tudo bem,sou do brasil e sigo voces aqui pelo youtube, estou fazendo uma manutencao em um veiculo sprinter 907 com motor om 654 se tiver o manual de reparacao desse motor para poder compartilhar comigo ficarei muito grato

👏🏼

do you have a video of the om603 lifter or cam replacement

Really great video, I've seen hydraulic lifters fail on om651 but never on om654. How did you torque the sprocket screws, not much space in the back due to egr cooler.

I'm wondering if the " Failing Rocker Bearings and Hydraulic Tappets" issues can be resolved with new parts? As in did MB resolve the issue but improving the parts or is there aftermarket parts that prevent the issue from ever happening again? Is there a specific thing that can be done to make these parts last forever?

Great video: What do you think - has start/stop system or long oil change period something to do with this damage and is this fix coming inexorably to all OM654 engines sooner or later?

Love the content. I've replaced the rocker arms on my w213 e220d . I have a fault eml comes on and throws a P0017 fault code

When this plopping intake sound is present is it always the rockers or can it be problem with egr or something else? I have the plopping sound and only error code is P0101FA MAF faulty values that triggers constantly. When running throttle valve test in Xentry the engine become completely silent for a short time.

Hi. Very impressed of job that you have done with merc engines. Any chance that I can have appointment with you to check my car's engine please? Thanks

Hi Mercman , i want to ask you how much is the cost of the parts you have changed . Thank you

How much NM you tighten psv valve cover?

Can this problem of uneven engine operation only occur in neutral gear? when it is on D the engine runs smoothly.

Hi bro where is your garage in the uk?

We got few 654 with over 200k nothing wrong with them... oil changed maybe 2 times.I do not know what is wrong with some examples

Great video. Was this issue resolved by manufacturer with newer models (2019-2020)?

Another great video i begin to wish i had stuck with Mr volvo rather than Mr mercedes.

How much is the degree of clamping of camshafts Nm??

👌👏

Hi Mercman. How much would this kind of repair cost approximately on a OM656 engine? Parts and labour? Much appreciated! Zhivko

Where are you guys based mate? Woukd like to come down and get my car checked out..

Hi how much do you change for this

How much costs same job on om651?

Hi great video is it the same problem in 3.0 om656 ? Thank you

Bro where is your garage? I have the same issue on mine.

Great video. Jeez the quality of MB is just continuous slope down. How they manage to still sell this crap they manufacture is hard to understand.

Hey MercMan , how do I get in touch with you about booking some work in please? Thanks

Merc Man do you have contact information I need oil cooler seals to be replaced on my w212 thanks

Oil pump failure at 47k on this engine do I need a replacement engine 🙏

I also have a Mercedes E class from 1997 engine 2.3, is it the same way?

How many miles????

Is the engine running on all 4 cylinders at this moment, without an error message in the speedometer? Is the noise where you can tell ahead of time that the rocker arms need to be replaced before it's too late?

I am interested to know what is the cause of this as it always seems to be on the exhaust side... Nowhere can i find a diagnosis, or is it just poor quality rockers.... But the camshaft did look very dirty on the exhaust side.

Hi Mercman, do you have workshop. I would like to fix my car

Could please write the mileage of this engine. Thanks.

Where are you based bro?

Hi thanks for this video I have the same problem with same engine I'm a taxi driver so I'm wondering how long I can drive the car without further damage, Mercedes say I've detected the issue early.cheers

I have a 2016 E220 and this loud noise. I also have blow back coming through air box. Is this what you see from above issue also ? Thanks

For this problem not to come back you have to cancel all emissions system out DPF , EGR, and adblue. Because of emissions system is blocked this problem appears on all euro6 diesel cars. On that car definitely air inlet and outlet system is blocked and valves are clogged full with carbon.

did mercedes recognize their bad desing? are there avaible new desing? im planing on buy a w213 and dont want to have trouble

Did a full timing chain, new rockers everything and as soon as i started the car this noise was still here LOL

Would u likely get misfire issues

Km?

Hello mr, do you have codes for pieces that are needed to be changed? Thanks

Forgive me I am very stupid and not very knowlegdable about engines, but why does this DOHC engine need rocker arms in the first place? Cant the cam lobes just press directly on the tappets?

Hi ✌️✌️👍👍👍RUS

a reason to get the warranty...

Motorkote end special oil every 10000km!no problems for my Mercedes E300 de whith 867000km!!!!

Don’t you have to set the rockers? And also won’t the gears keep the camshaft in place? Sorry I work on ship engines not cars 😂

How.much to do this job

Has anyone completed this job without the locking tool?

Do you think this engine is better then the OM651 engine

yeni parcalar takiyosunuz onlar peki dayaniklimi

I had the same Problem with Mercedes e 220 2017 Mercedes i muss say i am very disapointed.

Hi what mileage does this start happening

Bro.....I just got a used C220D with OM654 and found this vid

How much is cost ?

How much it cost roughly?

What mileage?

Without changing the chain ?!?

I am taxi driver I had same problem but fix now e class 220 , 2019

- Hi. - Is this knocking phenomenon typical of the Mercedes W272 engine? - Waiting for an answer. - Thanks. - הי. - האם תופעה זו של נקישות' אופיינית למנוע מרצדס W272 ? - ממתין למענה. - תודה.

No manufacturer can make anything decent anymore, its all gone to shit engines with design issues from day 0 manufacured to survice maybe 200.000 miles if you are lucky and wear out atleast 2 timing chains getting there. Take the OM611 and nearly identical OM646 for example. Those were dead simple durable engines. Double roller timing chain that will outlast the rest of the vehicle and no other significant mechanical issues. They last a long time and since I am thinking about buying a cheap used Van Ive already settled on a Mercedes Vito instead of a VW because they came with those exact engines in them and the older Mercedes Automatics are also very long lasting aswell so a W 639 Vito with the OM646 and Automatic Transmission would be a dream. When you look you see older Diesels with tons of miles on the engine like 200.000 300.000 and more. Do you think any of these new junk engines coming out will survive that? I have a near 20 year old Volvo V70 with the five cylinder D5244T Diesel. 95% of the parts under the hood are original and the engine has done 250.000km. Never needed anything changed. Runs like new. Virtually no wear. Only ever needed oil, filters, belts, pulleys/tensioners and a waterpump. Makes 160hp, plenty of torque and fuel efficiency is good. I will do an EGR + Intake cleanout this year in addition to my regular maintenance and probably fit an EGR blockoff plate since it helps them from sooting up the intake manifold and improves fuel mileage slightly. Before I aqqired the car service records indicated it had 0w30 at 30.000 kilometer intervals. So the absolute worst you can throw at an older Diesel engine. Volvo is delusional and stupid enough to have 0w30 at 30.000km as their factory interval on their cars. The engine vibrated a lot and the valvetrain was noisy as hell. I put in 5w40 diesel oil and change that every 12 months or 10.000km. The engine survived the previous abuse flawlessly and runs so smooth and quiet now on 5w40 its hard to believe. No manufacurer these days builds engines like that!

These E class can go up To 300k some without any problems, there is no reliability issues, don’t damp people’s abuse on Mercedes pls , I have seen people abuse these cars!!

Ford ecoboosts german cousin. Crapcars designed to fail..😂

After being told for the past 3 months by multiple mechanics that I need a total engine replacement and that my engine is completely damaged (diagnosis purely given on sound alone) I’ve randomly come across this video!! Completely shocked as the sound this engine is making is EXACTLY the sound coming from mine! Mercman do you have a contact number/email or website I can get in touch with you on?

how many miles it has?
