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!!!

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

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

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

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.

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.

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

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

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.

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

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

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

Definately best video about oil cooler Seals.

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.

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

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...

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. 😉

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

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.

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

Subscribed already . Lots of information . Thanks .

Love the new intro!

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.

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

Real Craftsmanship. ✌️

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

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

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!

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

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

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

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

With the rigth tools and passion everything can be done ❤

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.

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.

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

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.

Great channel mate love the vids 👍

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!

this is the best video i have seen greets

Doing my first tomorrow great help thanks

Nice old sealing collection! Kind of trophys (-:

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 ...

Excellent video. Thank you very much.

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 ?

Excellent video

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

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

NIce video, and very helpfull thaaanks!!

Respect!!! Insane how much work :/

Great vid! Planning to do this with my neighbour’s 280 v6. Any recommendations on other gaskets to replace while i am down there? Regards, Willem

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.

@MercMan Tips thanks for this video. My car decided to start mixing oil and water, could this be the culprit? My car has never overheated before, and it seems this may solve my issue to replace the seals on this. But I don't know? Hope you can tell me if this could possible and hopefully be my only issue.

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

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.

Thank you it's great Job 👍👍👍

Awsome video! 💯

as a general idea how much do you charge for a change? I have a jeep grand cherokee 3.0 CRD with om642 and I think I have same issue

You made it look easy 👊🏾

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

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

Best video , thanks for this bro

Are you UK based? What is the main cause for them to go in the end i have slight leak now, can it leak around engine sump? Or is it mainly by gearbox as you said?

Awesome video thank you.

Great video👍

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.

Great video. Thanks.

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!

Thanks mate for the video Just a quick question Any suggestions regarding liqui moly CeraTec oil additives to this kind engines. Mine is a 2013 Vito 122 CDI V6 Thanks in advance

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.

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.

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.

Hello,is the 2012 265hp w212 ones has the same problem? if so,how can i understand that same issue is ongoing by the easiest way from outside?

Hi any suggestions on removing the bolts on the turbo because they use to get stuck

Professional videos, thanks

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?

perfect video thank you

Nice gaskets what if you put a minimal amount of silicone with the new gaskets will that last longer?

Do you know maybe which motor oil is better for W203 220 cdi om646 without the Dpf ? ( Mobil1 0w-40, Oem Mercedes 5w-40 (229.5) or Mobil X1 3000 5w-40) ? Thx

Hi buddy Do you normally just replace the seals and reuse the old oil cooler or you install a new cooler every time? Just about to order the parts as I am planning to do this job in the next 2 weeks. Thanks in advance

Great video thanks. What's the cost of this job and plus the inlet port shutoff motor? Thanks

Hi MercMan Tips ! Great job , need this things changed on my car Where You located? Wonder how much time it take for this job ?

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

Would you think a diy could chase this one ? Biggest job I’ve done was pcv on e39 . Thanks

Hi Merc Man, have you done the oil cooler seals on a crd 3.0? Do you always replace the cooler itself or just the seals?

jesus that really is a massive job

Good afternoon. Is it possible that if these seals malfunction in the heat exchange, oil will appear in the coolant?

Hi, my mech add some silicone (1,2mm) on oil cooler seals,it’s okay ? Thanks

Hi guys, I have a Jeep Grand Cherokee which has the same issue, have you ever done the seals on one of these? If so how much would it cost for you to do them? Where are you based? Thanks

Excellent Video. Thanks. How many hours of work should this be?

How much torque needed for the two t45 torx bolts mounting turbocharger to the pedestal? Thanks for the video.

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

mine leaks oil from the intake silencer resonator is it normal?

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

Noticed the manifold gaskets but what were the small ones?

Really good video. Hi I’ve got a Viano 170k miles got a massive oil leak. Have you done one on a Vito/Viano?? Thinking of having a go myself with help with my friend who is a Machanic. Anything I need to know before I start??

How long does the job like this take you to do and how many gaskets or what would I need to buy. I have the same car I have the same problem is it worth my trouble I am mechanically inclined.

Can you tell me when you did this job did you need to change replace parts part# A6420906537 and A6420900637 ? Thanks for the video!
