Thanks for the video mate, its just wonderful how clearly and patiently you explain all, just needed to ask 1 question. What all other, if any, gaskets(seals) do i need to replace during the job other than for intake manifold?

[@LMAutoRepairs]

Vikram Sahu Hi Thank you for watching and for your comment, really appreciated! I believe I have already answered that question, but here it goes... Ideally I would replace every gasket or seal that gets disturbed during this procedure... simple as that... In this case, I was stuck to how much the owner wanted to spend... So that is really my advice, will only add a couple of £10 to the bill...

[@RZiggyMarshall]

@@LMAutoRepairs Hello, I believe I have this same issue and was wondering where in the comments did you list the other gaskets/seals that you recommend to be changed at this time of doing this procedure, I tried to scroll through as many as I could, but didnt see where you listed the other gaskets/seals outside of the two oil cooler seals. Can you point them out to me... thanks!

[@LMAutoRepairs]

@@RZiggyMarshall Is right here... fixed at the top... Ideally, you replace every single gasket/seal that gets disturbed during this procedure... Hope that helps... Thank you for watching and for your comment!

[@monkehbitch]

For the job, When I tackled it... I was initially hunting a boost leak but came to this situation where I knew I was already 3/4 involved in removing the manifolds. I replaced, Both intercooler seals, Seals between the anti-shudder valve, EGR seal, rings on EGR cooler, O rings on intake manifolds, Turbo boost pipe O rings, EGR gaskets, The aluminium link pipe between manifolds, intake manifold gaskets. Unfortunately, It added roughly £80 on top from merc for the seals...

@@LMAutoRepairs you're welcome. There's 2x E12 bolts under the turbo (pointed out in the video - almost impossible to see !) Have the left one out but the one right underneath the turbo housing looks physically impossible to get access to let alone get out. Any advice as to how to remove this please ? Also the 2x T40 (?) bolts at the front of the turbo, are these T40 or a different size please ? Mine are fairly rusty and don't want to take the risk of rounding them off. T40 feels a bit loose but T45 is too large. Any help/advice really appreciated

Excellent job. I will be doing this on my 2012 E350. This will be the second time.. first time it was done by the dealer at 75k miles...car now has 167k mikes and the oil cooler is leaking again... I guess those leaks weather orange or purple... they last for about 75-100k miles. What happened to that top noch German engineering... they can’t figure out how to keep oil in the engine?

[@LMAutoRepairs]

[@fredb711]

Great video. Thank you for taking the time to document the job so thoroughly. Reason I watched is I am possibly going to pick a 2011 GL350 Bluetech with 175k miles and a list of issues, including this oil cooler leak according to a MB dealer where the car was recently serviced. The dealer said that the oil cooler itself also needed to be replaced for a total job cost of US $3,380. Does the cooler itself typically fail? How would you determine if the cooler itself needs replacement?

[@LMAutoRepairs]

Hi Usually is the seals that fail... Never seen one that the cooler was the problem... But if you are unsure, pressure test it... or replace it... They are not that expensive... Thank you for watching and for your comment!

[@hsmautoservice158]

Just got the oil cooler freed up on the E350 and noticed a few (annoying) differences which are some that others may run into as well so here is the info: The exhaust side has the kat mounted directly on the turbo, so no short L pipe there. This presents a bit of a challenge since it is only to be removed after loosening a clamp which is factory wise not reachable unless you dismount the crankcase ventilation on the right back of the engine. Also as you noticed there is a bracket holding the exhaust inlet sides on the turbo with 2 bolts on the back, which should be negleckted, just go for the 2 you can do from the top and take the bracket out with it. This i the main stuff, the rest you will figure out on the way. Just make sure you get the inlet runners out together due to the system of plastic adjusters for the swirl valves. Don't want to break those! Most throuble gave me the stuff others caused due to other repairs (rounded bolts etc.)

[@LMAutoRepairs]

HSM Autoservice Excellent piece of information... thank you for sharing it!

[@shefi14]

As always great video and very helpful. Thank you! I have a question, how you have diagnostic the problem was on oil cooler leaking and no in other place, so what direction of diagnosis you followed?

[@LMAutoRepairs]

Hi Thank you for watching! This one came already diagnosed... This however is a common problem, but, with a torch, look down around the turbo, you will be able to see the end ofvthe engine block and the area where the oil accumulates, so if you see oil in there, bingo! It might be other ways, that is my one... lol Hope that helps...

[@adrianjakeman9035]

Hi, Early in the video you mention the breather of the pipe from the turbo, I have been told that this and the pipe can also leak so have you experienced this and are they expensive replacements. I have an E350 CDI Blueefficieny and I've seen oil around this area. One other point from watching video is should turbo bolts be replaced?

[@LMAutoRepairs]

Hi Torques in the video description... Thank you for watching and for your comment.

[@W15Garage]

Good video mate! I was wondering if you’ve changed the oil cooler as well, or just the two purple oil seals? I’ve just finished this job on my e320, changed the purple O ring seals, and intake gaskets but I think the oil leak it’s still present- 3 days after the job was done I’ve seen some oil drops on the ground, under the car. I did not used a torque wrench on the cooler bolts...do you think that can be a problem? Thanks in advance Vilmos

[@LMAutoRepairs]

Hi I have done this job a few times, but have never changed the cooler... I have always checked them for leaks though... It can take some time for all the oil to come of from all the conducts/drains... so allow a few more days.... Hope that helps. Thank you for watching and for your comment!

Huge respect for this film. I would like to do it with me and I would like to buy all the seals to buy before work. Do you have information about the numbers of seals needed for this job. I have been wondering for several months and I will try to do it for myself, even if it lasted a week.

[@LMAutoRepairs]

Unfortunately I don't have any numbers... But, you can dismantle everything... and then just get all the seals you disturb during the process... At Mercedes they will show you the drawings of everything... really easy to figure out.... but you can always take the old ones... You won't take a week... believe me...

While the engine is massively opened, I will probably replace all glow plugs, clean egr valve + complete manifolds, replace thermostat and replace that oil cooler.

[@ingoschneider8532]

Sorry for being not careful enough reading the comments. 8 hours is pretty OK. So assuming about €110 per hour incl. VAT it will be around €900 labor work and some money of the spare parts new houses etc. I recommend to also replace the EKAS as it quite often is drained in oil.

Thanks for the video, very good reference as i have to do the job myself to save $3000. 2 questions. Are the torque numbers the same for the ML320? Looks very similar. What needs to be done with respect to fuel under pressure in the rails and fuel lines before removing? Cheers.

[@LMAutoRepairs]

Hi I would say the torques should be the same... same engine after all... As for the common rail lines, just make sure you keep the key out of the ignition, and leave the car alone for 5 or 10 minutes before start to undo the lines.. the pressure will be gone by then... Thank you for watching!

I just did this work on my personal 2013 E350 Bluetec. Apparently they put some GL350 parts that are normally not in a regular Bluetec. When I look up certain parts to get the numbers it shows it does not fit my car. The build date is 10/12. My motor has a oil changeover intake near the front. It also has a 1 piece instead of the 2 piece exhaust pipe that attaches to the back of the turbo. A little harder to get out due to the lack of room, but still managed. MB also put in the orange seals instead of the purple ones. I thought they found out the the orange ones would leak and no longer installed them on later model years. Do you know anything about that or did I get the wrong information on the year. Your video was great and very helpful especially the torque numbers.

It would be the pipe that goes into the centre of the turbo below the sticker with the QR code. It is a moist sandy type crud that's black. Just below that pipe there is also some residue. Any ideas what it could be? It is still under maintenance plan but need an honest opinion in case they tell me otherwise.

[@victorsinclair188]

Did you take it in? I assume so since it's been 3 weeks. I don't think and shop would mess you about on such a common issue to these cars. What did they say to you and what did you do about it?

[@SDav21]

@@victorsinclair188 I did. First they said it is "sweating" and is normal but I said some residue around any part in the engine isn't normal. They did however change it still under maintenance. They also change the transmission oil even though I only have a out 38000 miles but I guess it would have been replaced had the car not been such low mileage anyway. The item to service is the one to service regardless of kms anyway I guess. Just odd as to what they service and what not. Apparently the cars computer generates a workshop code which tells them what must be serviced. So it could say change the cabin filter yet not the engine one. So odd.

When i can book my cls to have same job done please ? You far away of CV227 ?

[@tomasmelinis2125]

Hi mate,I’m just bit confused needs change only seals? Or change all kit oil cooler&seals? Thanks

[@LMAutoRepairs]

If you watched the entire video, you would see that I left the same oil cooler... The seals are what are common to fail... Obviously check the cooler for leaks, and replace is necessary... Thank you for watching!

[@mikhailjoukov3910]

Good day, did you oil the new seals for installation like you would for an o-ring?

[@LMAutoRepairs]

No need... But you can do it... doesn't really makes a difference... Thank you for watching and for your comment!

Does anyone know if this issue is fixed on the W221 S350 cdi from 2011/2012?

[@BELHORIZON31]

Hello, any issue regarding the turbo with om642 engine? I just purchased a second jeep grand cherokee with this engine with turbo problem it could be related to the oil cooler? I was stuck with my small familly in the middle of the national road within a country side around farm running on idle. Thanks for your help

[@LMAutoRepairs]

Esposito John Hi I can't see how the oil cooler would affect the turbo... unless you would loose that much oil that the turbo would ran dry... but you would have bigger issues by then... Plus probably a bunch of warning lights for oil pressure, lever etc... Have you removed the intake to inspect?

[@BELHORIZON31]

lmsvvavr not yet but i’ll remove the intake for a check, thanks for your help

[@SDav21]

Do you know if Mercedes fixed the issue by changing the seal on later models for example the W212 E Class facelift from 2014 onwards.

[@LMAutoRepairs]

Hi As I have explained in the video... The newer seals resolved the issue... not sure from when they have been fitted... I would guess that 2014 should have the new seals.... Thank you for watching and for your comment!

[@SDav21]

@@LMAutoRepairs Thanks. I hope Mercedes used the new seal type from the factory.

Hi Sir I have a mercedes r320 cdi. Over the last seven months or so I have noticed engine oil stains on my driveway,. I have taken it to few workshops but they were unable to figure out where the oil was coming from and decided to not investigate further. I drive my car regularly and have never encountered any issues or warning lights on my dashboard. I have watched your video and first of all thank you for sharing your knowledge. I believe my car has a similar issue. will this get worst in future or will the leak stay minor? i would appreciate your response

[@LMAutoRepairs]

Hi It will most likely get worse over time... So, you will see oil dripping just by having the car at idle... Hope that helps. Thank you for watching!

[@sss8316]

@@LMAutoRepairs what is rough cost to fix this kind of repair?

[@LMAutoRepairs]

Don't know... I mean, is quite labour intense... so any garage will charge you at least 1 day of work... Just guessing though....

[@tunaaa94]

Hello thank you so much!! I have an E 280 CDI with OM642 from 2008. Until now i have no problems with this part. There is no oil under the car and i do not see any oil loss. Should I change it as a precaution? My car has 220.000 KM now... I would be very happy about an answer! Greetings from Germany!

[@LMAutoRepairs]

I guess that if you are willing to go for it as a precaution... why not... but I guess you can also just leave it untill the seals fail... It is your decision really... I know is not a very definite reply... but hope it helps... Thank you for watching and for your comment!

I have got a ML350 AND I JUST WANNA KNOW THAT AS PER MECHANIC HE WAS TELLING ME THAT THERE WAS A LEAKAGE SO I THINK IF WE CHANGE BOTH THE O RING OIL COOLER WOULD BE OK???

[@LMAutoRepairs]

You can test the oil cooler... or just replace it... they are not that expensive to be fair... that said, usually the cooler doesn't leak... it is the o-rings that do... 👍👍

[@TheTurbinator]

When you put everything back together, and primed the fuel system, and the car just completely refused to start - that was terrifying. You got any clues as to why it took over 10 trys before it started?

[@LMAutoRepairs]

The fuel systems get empty when you disassemble it... so it is normal that the car takes a few attempts to fill the system and fires up... This engine has 2 rails, etc... so is a fair big system to fill... Thank you for watching and for your comment!

Rail nuts - 20 Nm is NOT correct... it´s 27 NM between the rails and for all railnuts for the nuts to the injectors it´s 33 NM and next time, please CLOSE all lines from the rails! one particle of dirt and the injectors are dead

No worries... Even if that is correct, 7 Nm is not the end of the world... 👍👍👍

[@tommimetsapuro5382]

how long approximately to do the job if you already have all the seals and tools?

[@LMAutoRepairs]

Depends how quick/experienced the person doing it is... I would say, if you never did it, 12 hours or more... if you have experience and do it faster, 8 to 10... The last one I did, took me about 9 hours or so...
