Probably one of the best car repair videos I’ve seen, love the format of “show and do” simple but effective

FOR THE LOVE OF GOD! please everyone reading this comment remember to replace the O ring that sits on the EGR cooler under the manifold. I did this job with my ol' man and after a long time putting it all back together the engine coolant was pissing out the bottom so we had to start all over again from the beginning 😭😭😭 learn from our mistake and purchase that seal!!!

This is the best approach so far. Thank you for posting this video.

This is exactly what I needed!!! Thank you so much. The editing was perfect to, straight to the point! Cheers mate

See i told everyone those engines weren't that scary...Thanks great informative tutorial im waiting on a gasket kit now...

Essential video, original style, very well done. It doesn't go into the details of how to dismantle the individual parts, but gives a quick overall idea of ​​the work to be done, what will need to be dismantled step by step.

Hi merc man ive changed more than 30 sets of oil cooler seals mainly on w164's. I leave the thermostat housing on taking the long bolt out and leave the swirl pot motor attached to one half of the manifold. Disconnecting at one point towards the turbo, makes it slightly easier. Best time 5.5 hours drive in then road test all parts ready to go including brake cleaning oil down. Some do take longer, bolts on turbo and egr need to be changed other wise they have a greater chance of snapping for the next guy. Like your clip simple piece by piece break up. 😉

Great video. Thumps up from my side. Thank you for sharing. But please also add important information's for all watchers. 1. be careful at the moment where you are removing the turbo-holder. At time 3:33. There is a hole which goes directly to the motor-center. It is the oil channel of the turbo. If there some dirty stuff falls in, then you are risking a motor damage. Be sensible and clean it carefully immediately. And close with paper towels the hole before you proceed. 2. after you are done, please make an oil change before starting the motor. Water and dirty stuff is mixing through the oil holes under the oil-cooler. I got a lot information's where after this oil-cleaner change the motor got damaged through this dirt-water stuff. If you are done with the change of the oil-cooler and oil+oilfilter, then you should release a plug of motor electric and give some start tries to turn the motor/pump and so on. After several turns, plug the removed cable back. Start the motor and of course delete the occurred error message in obd. These are just my hints for the community in yt ;) Wish to all much success...

Wow! Thanks for making this video. I see why the mechanic is charging 10 hrs of labour for a GLE 350 blutec. Amazing skills!

Great video still can't believe all this work to change a couple of oil cooler seals. Mercedes engineers.

Great help. In the middle of this job for the first time and this just what I needed !!

Definately best video about oil cooler Seals.

if i could add one comment other than nice clear vid , one tip id add is when reinstalling intakes loosely install the bolts into the egr to exhaust flange shown at 2;48 in this video before you tighten down the bolts for the right hand intake manifold to save many stressful attempts to line up the bolt holes after the fact.

JUST an observation, lot os oil on the turbo intake, need new breather valve and watch out for blow by. GREAT VIDEO

Wow 👍that’s a big job for a couple of seals, and by your collection you’ve certainly done a few! Thx for doing the video.

Excellent job mate I was confused from two day I changed the main seal because of this leakage but now tomorrow I ll do this job regards

With the rigth tools and passion everything can be done ❤

Just wow. I wish I could make a KZfaq car DIY video half as good as this 🤣. This is by all accounts a pain the backside job to do on these engines - however your instructional video is so good that makes it look doable (if I weren't so lazy these days). Subscribed, great channel - keep it up!

Nice Video Mate. Wish I'd seen it before pulling the box and sump and then realising it cam from higher up, had her stripped in 2 hrs thanks to you. Bit longer back together. Thanks for taking the time to make the Vid.

Wow, I've just bought an S Class with this engine, 47,000 miles. I hope I don't need this doing 😩...what a job, kudos 👏 to you though for being able to do it, ...let's put it this way, if it needs doing in the future I might bring it to you ...

I changed mine about a year ago. From what I read, they said that the orange ones were used up until 2009 and the 2010 and newer models had the purple ones. That was not the case. My 2010 had the orange ones and oil everywhere! Thanks to a Malone tune, everything works well and the seals have been replaced.

I wish i had superpowers like you. :))) touching parts to remove them and 1 single touch to reassemble everything.

Great video! Anyone looking to buy a used 3.0 diesel should watch this then ask the owner if the service has been done.

I have a cls320 with the same problem... on july i will start to fix this problem. Thank you for this video, great job.

Real Craftsmanship. ✌️

Loved your vid, stumbled across this page while researching for the first one I've finished and completed today. Glow 1x glow plug connector broke on me "dammit" . Wish i had seen this earlier :) Never mind. Well done.

Super Super Super Video. Dankeschön für die informative Teilung und Ihre Erfahrungen. Respekt 👏👏👏👍🤙

Hey man! Love your vids. Keep up the good work. When the opportunity strikes, maybe a video on OM 651 timing chain replacement. Cheers!

I had that same breakdown 4 years ago with 170,000 km and my mechanic changed my oil radiator because he said that they went bad and were oval.

fantastic video. I have to change my oil cooler and was wondering if I tackle it myself or fork out thousands for someone else. I was able to follow your steps so I feel a bit more confident about doing it Thanks

Great job mate,very helpful for the e350 owners.Let me gues,the seals probably not expensive,but to much work to get them changed!

can you make a video how you rebuild it step by step :) very nice work i love your Videos Thumbs up for you

This is a brilliant step by step video. Very good work and thank you for sharing.

Nice old sealing collection! Kind of trophys (-:

Oh my! That’s more than I would be confident to try and do myself! But thanks for the video 👍🏻

What do you mean $1500 in labor??!?! Its a 9 minute youtube video!!! Great work!

omg thank you man ive been working on this all day and couldnt even figure out how to undo the turbo! Probs to you

Remember to be very clean and before removing the turbo pipe or oil cooler to clean all the sand and debris. If you don’t sand or debris could find its way above the crankshaft bearing and seize the engine.. i have seen it happen when i worked for mercedes a few years ago.

Perfect. One thing to add, change your thermostat and any other perishable seals like egr seal at same time. Don't forget the injector seals.... Replace those old copper seals too.

and here’s me thinking that doing N57 oil cooler gaskets are a nightmare 😂

Great video! That's what I'm looking for. Well done buddy! Thank you and keep doin your job like this.

this is the best video i have seen greets

That does not look like a diy project, at least not one I would ever tackle. I think those orange seals are rubber and the purple ones are neoprene. That should be a lifetime fix. That diesel sounds so sweet. I would love to have one again instead of my 01 e320.

Awesome Job, awesome video. Shortly and informative. I dont understand not so much(english) but i think man dont need the language for the work ;) Grettings from germany.

An additional oil separator with crankcase gases must be installed on these motors. The engine will live longer, swirl flaps and particulate filter . На эти моторы надо ставить дополнительно сепаратор картерных газов с возвратом масла. Двигатель дольше проживёт , вихревые заслонки и сажевый фильтр.

Had these done on my s350 last year at main dealer £1200 they better have put them purple seals in 🤞🏽

Fecking magic hands that just undo the bolts and nuts just like tha Must be Tommy Cooper!

Subscribed already . Lots of information . Thanks .

Awesome video! Useful! Needs just list of gaskets in description.

Oh boy ! Mercedes and BMW are Kings when it comes to this ! Plastic in your engine worn out ?? No problem, the part only costs 30 quid, then there's the grand to fit it, plus vat !

Excellent video! So glad I ditched my Grand Cherokee WK before I had to do this job!!!

Respect!!! Insane how much work :/

Love the new intro!

Thank you so much, got my MOT coming and its dripping XD

NIce video, and very helpfull thaaanks!!

Can you please list all the other gaskets that you replaced? One is manifold. What are the other ones? I will be doing this repair next week. Thank you!

Excellent video

Great job on vid. Have mine apart for this same leak on Gl320. Not a fun job and the clean up on the intake runners and ports suck.

Man, you are God. Thank you for the video, for each of them :)

Best video , thanks for this bro

Great video. This is the second video that I watched today about this oil cooler. It seems scary this kind of job.

Great video! I'm wondering how long does the fix last and have you seen any OM642 leaking again after replacing the seals? I'm viewing an 2012 ML350 this weekend and it has had the same issue and Mercedes fixed it with Mercedes parts in 2018. Mercedes replaced the oil cooler seal (MA642 188 05 80), oil cooler sing (MA642 180 01 65), and bunch of other gaskets. And looks like the Mercedes parts have defects and would not last long, I'm worried that the oil leak will happen again on the car I'm viewing in a few years. Thanks!

I need my seals replacing, how much does this guy charge to do the job, ill travel happily to get it done

Hello great video, I had a question: How did you cleaned the oil off. Ive replaced the oil coolers seals but i haven’t found a solution to clean all that oil out.

Those trophies though. *shiver*

Great video unfortunately i have the same problem on my c 320 cdi i hope garage can fix it

Thank you so much .. from malawi

Hi @mercman, I believe I have this problem on my E350d. Are you based around South East London? Or do you know any garages that will fix this in the area? How much do you estimate the cost would be ?

Cool. Mine has same problem. It must take a day to do it all.

Professional videos, thanks

jesus that really is a massive job

MB f*cked it up big time on this model. The leak does not stop until you replace the gaskets with the upgraded purple viton type. This tells you that MB acknowledges the issue but refuses eat the cost. The purple gaskets themselves are $5 each but the entire gasket kit is $105 retail at MB parts store. The local dealer charges 15-18hrs of labour, $240 per/hr being the current rate. This issue occurred on my 55k miles driven E350 Bluetec, its sad the owners have to pay for it. Otherwise, this is a good car and a good engine. This is an easy but time consuming job, however its doable by a DIY'er.

Thank you it's great Job 👍👍👍

Doing my first tomorrow great help thanks

I have just developed the same problem with oil cooler 280 cd1 w211 642 motor. Could you advise expected time to repair as per video and how bad is the removal of the bolts in the high temperature areas , turvbo exhast etc

great video. i had a question for you. i just finished doing this big job. and did all gaskets. i cannot get rid of a p0211 code. i get that code with my autologic scan tool. the code sais it is in relation to injector 1 bank 1 side. or it technically sais injector 11 . i get the following codes as well B3800, U2c18, and c1200. these all seem like error codes. car starts fine. and idles perfect. only time check engine light turns on is when it is actually 1 mile or more on acceleration. then goes into limp mode. i did not have these codes before. but wanted to run this by you. my scanner has no adaptation settings or any type of resets. wires are not broken, i switched out injector also. and also fuel filter. i checked and cleaned the fuel regulator as well.

Did you know that the core problem is that the orange silicone rubber gaskets are incompatible with the diesel oil? I first noticed this when replacing the turbo inlet seal after only a year and I could rip it with my fingers. Mercedes replaced it twice at 100 000 and 200 000 km. I also had oils leaks on the vacuum pump that has the same rubber gaskets

Can you share the torque specs for this job? Much appreciated.

Is there not a good aftermarket solution for this? Something the permanently mounts to the oem location and allows you to route hoses to an aftermarket cooler?

Great video. Now, please, would you also do one for the OM629 4.0 V8 diesel engine too?

Excellent video! Thank you! Question: Is there any reason to also replace the cooler itself when changing the seals?

Love the trophy collection of seals :) Where are you based mate ?

I need this on mine. What does it cost to do this? Great video and liked the style.

Excellent video. Thank you very much.

Awesome video thanks. Where can I find a good torque spec for putting it all back together and all the torque specs for that? Do any of the shop manuals do a good job explaining the repair? You video does a great job explaining how to get to the seals but Im guessing you just didn’t have time to do the full video.

You made it look easy 👊🏾

What is the tightening torque for the manifold and turbo, and can a person who is more of an amateur mechanic who repairs minor things on the car deal with the radiator gaskets?

Salut ! Cumva baga ulei în vasul de expansiune? La mine nu baga , doar ca îmi mănâncă ulei ,dacă schimb garniturile alea mai consuma ulei ?

Great channel mate love the vids 👍

What year of 350 cdi did they fix this i have a 2012 cls with same problem, im selling it ina few days and want to buy a 2015 or 2016 cls 350 cdi

Hi there where are you located? I have a Chrysler 300c crd 2006 with the V6 Mercedes engine and have the oil leak problem but can’t find anyone to do the job for me, I would like to come and see you about doing the job, regards Ergun

Love the video! Dreading the day I need to do this in my Jeep.

How much will this cost on average to repairs plz reply my cars has the same problem just bought it 6 months ago 😭😭

This is the best vid on KZfaq showing this is, subscribed. How much would you charge to do this on my 2008 E320cdi please?

I have 2014 gl is it same engine? And can you please share how’d you clean all that oil before installation and what seals should be replaced? Thank you so much for your time.

Thank you for the effort. Congratulations. How long does it take to dismantle the annexes in terms of time?

Thanks for showing what it looks like from below, before you dig in. Helps to diagnose. Are there other ways to know for sure it's the oil cooler leaking before you dive in?

Omg what a cluster. Is this reason enough to only get the OM651???

Who’s also here for the hand signals 🤣🤣

I think have a same problem you have some address or you just do this movies? Grate job thanks for showing
