A great video on the changing of the oil cooler seals. It seems insane how much work is involved in changing two seals. I have this job to do on a friends ML in a few months. I have sent him a link to the video just to let him see how much work is involved
Mercedes main dealer in Oxford quoted me £1700 to do this job a couple of years ago, which I couldn’t really afford being a pensioner so I had a so called mercedes specialist do it for half that price, but low and behold it’s needs doing again obviously wasn’t much of a specialist 🤷♂️now that I’ve watched your video on how it’s done I can see why it cost so much, nice job and a great video cheers 👍👍👍
I did this job myself after being inspired by your video. Thanks To anyone planning on doing this job, also change the swirl flap motor and runner rods. I had to do it again as the motor failed 2 weeks after.
Just as I get excited about buying a diesel i now hear about parts deep inside the engine that can break. The landcruiser 470 petrol now suddenly dont sound like a bad idea anymore😂
Awesome! I just finished this job on my 07 r320. I used awesome cleaner and brushes from harbor freight to clean the intakes and any black death. Melts it instantly.
Nice one, thanks for sharing. Some people also use pure caustic and steep them but I found my method is also as good and a bit cost effective. Thanks for watching
Something to watch out for very carefully. The oil line in the turbo stand goes directly to the rear main crank bearing. If any dirt goes in there the engine will break. So watch out everyone that is going to do this.
Doing this now on a 2012 W166 with the later version turbo which has a solid metal coolant line that is stuck hard from grime/age requiring excess force to remove, best order a replacement in before commencing the job P/N A6422030602. Also the downpipe is one big piece which makes removing the turbo a real PITA. Recommend removing the engine bay rear access panels and wiper cowl cover, still a real PITA job. Thanks for the vid, would be near impossible without it.

Hi. Great information, thanks for sharing. In terms of diagnosis, at what point can you see if the oil cooler is leaking, fuel filter? Mine is leaking on the right hand side behind the starter motor after it was all cleaned off with brake cleaner
@@TheKeenMechanic many thanks, only 60k miles. A very nice car. Will take my time. From experience, it’s easy to spend more time cleaning engines parts than it takes to disassemble. Great info
Great video. I have replaced my o rings once before myself but now 3 years later I think they are leaking again. Have you ever had to replace them a 2nd time? Could the oil cooler be warped?

Hi i have a question, not to this car, but the BMW F30 N20 Engines, they made a revised timing chain guide, which is white, original faulty one was brown, say this was replaced with the new white one, after 15k miles ish would the chain guide change colour to dark brown, or what colour would you say it would be, i bought a car a while back that has receipts that timing chain was done, but the guide is dark brown, so im trying to figure out if they actually changed the timing chain or just made fake receipt
Hi A white guide will never turn brown even after 300k miles. It will discolour but not that much. It will be more like yellow-white. Either not honest mechanic or used cheap parts

Hi Please read up the other comments and you will see the answers as I have been asked this question before. Thanks for your time to watch and leave a comment
This was my 1st experience with OM642 engine. I had big trouble removing the 3 bolts at the back of the turbo which took nearly 6 hours by itself as I had to bend and weld custom tools to loosen them up without snapping them or rounding the heads. I would say all together with all trouble, cleaning and filming took about 30hours. If I was doing it again it will be 12 to 16hrs with good detail.
Hello , Vielen Dank für das Video. Ich habe eine Frage - möglicherweise tritt Öl in das Abgassystem ein, und ich weiß nicht, was der Grund dafür ist. Liegt das Problem am Motor oder am Turbolader? Alles andere am Fahrzeug scheint in Ordnung zu sein. Ich habe das Fahrzeug gekauft und der Verkäufer hat mir versichert, dass weder der Turbolader noch der Ölkühler defekt sind. Dennoch tritt dichter Rauch auf, wenn der Motor heiß wird. Der Motor läuft reibungslos und klingt gut. Ich habe auch etwas Öl am Einlass des Turboladers entdeckt, wie im Video gezeigt.
Hello, thank you for the video. I have a question - maybe oil is entering the exhaust system, and I don't know what the reason is. Is the problem with the engine or the turbocharger? Everything else on the vehicle appears to be fine. I bought the vehicle and the seller assured me that neither the turbocharger nor the oil cooler were defective. However, thick smoke still appears when the engine gets hot. The engine runs smoothly and sounds good. I also discovered some oil at the turbocharger inlet as shown in the video.
I have posted the translated message in English so others can read it too. It is hard to tell without inspecting the vehicle in person. Is the smoke Black or Blue/White? If it is black smoke the it is most likely not enough air to burn the diesel. If it is blue/grey/white smoke it could be oil/antifreeze coolant leak. It will be very hard for oil to pass through the combustion chamber and to end up unburnt in your exhaust system. Make sure you have no turbo boost leaks which will cause the black smoke. This ML350cdi shown in the video was working very well when idling, but had no power and smoked black due to boost leak from a sensor that was not fitted correctly and had fallen from the plastic manifold which goes to the aluminium intake manifolds. Check the engine 1st and make sure you have no obvious boost leaks. If you know somebody who has a smoke machine get him to pressure test the intake system and check for leaks. Hope this helps
@@TheKeenMechanic The smoke that comes out is blue, a lot of oil enters the exhaust system / Sometimes white smoke comes out when the engine temperature risesThe engine runs smoothly and no malfunctions appear on the screen ,But the problem is the smoke and oil in the exhaust system
@@MN-nl3kp hi If there is nothing obvious you can replace or rebuild the turbo and see if this solves the problem. I found a company here that sold me a fully professionally rebuilt turbo for around £300 when I returned my old one. I hope the place you purchased it from offers a warranty. Check if coolant is leaking into the intake valves from the manifold. I have seen this before. This causes light coloured smoke too. Hope you get it sorted. 🤝🏻
If you have no leaks you can take a chance. If it is leaking it was either changed a long time ago, may be poor quality seals were used or never changed at all. Some last over 100k miles others fail much earlier. Hope this helps
This ML350cdi is year 2010. It had 190k miles and blew an engine 4 years ago due to poor maintenance. It received a used engine with 100k installed back then so I assume the current mileage would be about 150k on the second engine. I very much doubt that the intake and valves were ever cleaned. Hope this helps
Hi I have oil leak issue with my Mercedes c350 d - just wondering where you are based so perhaps I can bring the car to you for repair also if you give a rough indication of the labour cost involved in this sort of repair. Thanks in advance
Thanks - Unfortunately I’m based in Yorkshire and have booked it with a mechanic for this Friday, hoping it’s nothing too extreme. Once again thanks for responding.
@@TheKeenMechanic However not a good information for me - thanks for quick response ... I also have white smoke from exhaust and little amount of coolant dropping. EGR Cooler ? Thank You.
@@ukaszjurys2475 Check the bridge pipe with the two O-rings connecting the 2 manifolds. That is a very common point for leaks. Best of luck and yes, let us all know when fixed
Ohh man, have also replaced the seals with Purple (much stiffer ) bolted the oil cooler with 6nm, after two weeks much bigger leak. Appeard to be purple seals gone bad.. Got me another pair of Orange seals and did the job again. Any of you had this???
Oh such bad luck. I would hate to do this twice due to bad seals. I bought my purple seals from Mercedes dealer and I am aware there are many other cheap asian copies out on the market. Hope your dealer bought their seals from an approved supplier
@@madeinthehell1622 Save yourself £200 and use the old one. The only issue is the orange o-rings that harden over time and start leaking. Same as any other oil cooler, people just replace the gaskets🤝🏻
Hi It is a diamond coated router bit sharpening tool. Bought it 15 years ago so may be hard to find now but you will deffinitely find something similar
@@TheKeenMechanic Thanks I got some ridiculous quotes for this issue and not alot of mechanics want to work on it, so I guess I gotta roll up my sleeves and do it.
This was my 1st experience with OM642 engine. I had big trouble removing the 3 bolts at the back of the turbo which took nearly 6 hours by itself as I had to bend and weld custom tools to loosen them up without snapping them or rounding the heads. I would say all together with all trouble, cleaning and filming took about 30hours. If I was doing it again it will be 12 to 16hrs with good detail. I have heard others doing it for 8 hrs but I assume they did not go into such detail and cleaning. Consider yourself lucky if you get this done for under £500. Gaskets, seals, Oil, filters, coolant, cleaning chemicals and consumables increase the price even further. Hope this helps
@@andrzej5484 Hi, the engine was replaced 4 years ago, the previous mechanic used the old bolts and didn't put ceramic grease on them. The 3 bolts on the back of the turbo are hard to access and I had to make special tools to allow me to remove them without stripping or rounding the heads. Had to heat every single bolt with MAPP gas torch. Got there in the end but took a long time
So, after replacing the screws with new ones, secure them somehow, e.g. with ceramic grease, so that there is no problem with unscrewing them again? If there are new screws in the turbo and manifolds, what torque should they be tightened because you are giving different values.
@@andrzej5484 I just went with good and tight on the 3 turbo to exhaust manifold and all cast iron exhaust manifolds were tightened by feel as it is too difficult to use a torque wrench. If you are reusing the old bolts put ceramic grease on them. If using brand new bolts put ceramic grease too if they don't come with it.🤝🏻
A lot of labour to get to this cooler. Not a great design. As long as the seals last more than the warranty the MB dealer doesn't care what the customers have to do after that. The owner of the vehicle loves it and says it has been reliable in any other way aprart from an engine replacement 4 years ago which he admits is his own fault due to neglected maintenance
@TheKeenMechanic Fell out of love with Mercedes a long time ago.Once the (expensive) byword for quality but now just the same as all the other manufacturers.Overpriced and of questionable quality.
Absolutely the best video on this I have seen! I'm about to do this job myself on my R320 W251 -07
Thanks buddy, I tried to do it as detailed as possible whilst not too long and boring. Best of luck and hope turbo bolts at back are not too tight🤝🏻

@@madeinthehell1622 Yes the oil cooler was bought new as well, (however dont think thats the problem, even the old one was still good.)
What digital repair manual did you use?
Thank you.
Hi
I have access to the mercedes dealer repair manuals.
Thanks
How can I get a copy from you?
I want to make sure I’m reinstalling everything correctly.
Great video and thank you.
Sorry, you can't get it from me.
Check this website and get yourself one. Money well spent shrsl.com/43mz2
Thank you very much.
And the 3rd bolt of the charger? 🙄🙄🙄🙄
Hi buddy, what is your question please?
Hey what's the name of the tool or do you have a link for it at 37:22
Hi
It is a diamond coated router bit sharpening tool.
Bought it 15 years ago so may be hard to find now but you will deffinitely find something similar
@@TheKeenMechanic thanks I think I can find it here in Canada, what Grit is okay for the job.
@@Slim3rC10 above 1000 grit. Thanks for watching
@@TheKeenMechanic
Thanks I got some ridiculous quotes for this issue and not alot of mechanics want to work on it, so I guess I gotta roll up my sleeves and do it.
@@Slim3rC10 That's exactly why I put this video together to show people how to do it themselves🤝🏻
Good job done except that irritating devil's rock music....
Thanks🤭
Very impressive - a fantastic job done. Great video.
@@Orwic1 thanks🤝🏻
@@TheKeenMechanic hello, what city are you in?
@@fordeavalera9361 Hi
I am in Northern Ireland🤝🏻
How much is this repair ??
This was my 1st experience with OM642 engine. I had big trouble removing the 3 bolts at the back of the turbo which took nearly 6 hours by itself as I had to bend and weld custom tools to loosen them up without snapping them or rounding the heads. I would say all together with all trouble, cleaning and filming took about 30hours. If I was doing it again it will be 12 to 16hrs with good detail. I have heard others doing it for 8 hrs but I assume they did not go into such detail and cleaning. Consider yourself lucky if you get this done for under £500. Gaskets, seals, Oil, filters, coolant, cleaning chemicals and consumables increase the price even further. Hope this helps
@@TheKeenMechanic what's wrong with these compressor screws, why did it take you so many hours? what wrenches did you use? thanks
@@andrzej5484 Hi, the engine was replaced 4 years ago, the previous mechanic used the old bolts and didn't put ceramic grease on them. The 3 bolts on the back of the turbo are hard to access and I had to make special tools to allow me to remove them without stripping or rounding the heads. Had to heat every single bolt with MAPP gas torch. Got there in the end but took a long time
So, after replacing the screws with new ones, secure them somehow, e.g. with ceramic grease, so that there is no problem with unscrewing them again? If there are new screws in the turbo and manifolds, what torque should they be tightened because you are giving different values.
@@andrzej5484 I just went with good and tight on the 3 turbo to exhaust manifold and all cast iron exhaust manifolds were tightened by feel as it is too difficult to use a torque wrench. If you are reusing the old bolts put ceramic grease on them. If using brand new bolts put ceramic grease too if they don't come with it.🤝🏻
What a disaster,give me an aircoold folks wagen instead,

Truly awful vehicles.
A lot of labour to get to this cooler. Not a great design. As long as the seals last more than the warranty the MB dealer doesn't care what the customers have to do after that. The owner of the vehicle loves it and says it has been reliable in any other way aprart from an engine replacement 4 years ago which he admits is his own fault due to neglected maintenance
@TheKeenMechanic Fell out of love with Mercedes a long time ago.Once the (expensive) byword for quality but now just the same as all the other manufacturers.Overpriced and of questionable quality.
They are now installing Renault engines in the smaller class cars😮💨
@@TheKeenMechanic Daylight robbery
What spec oil does my mercedes use and how many litres? I have a 2008 E320 cdi. Thank you
