9 Week Update - Hi all, with a possible garage repair cost of between one and two thousand £ / $ I am overjoyed to say the leak is still fixed!, to be honest I never thought it would work but I only had a small amount of money to lose if it never worked, pretty much a no brainer really, if anyone out there has a issue with a oil cooler leak or maybe another type of seal / gasket leak I cannot rate this stuff high enough!, I will create another update video over the next couple of months so stay tuned, all the best of luck all with your leaks and lets hope the BlueDevil works for you! mrix
Thank you for the video. My car (2012 C350) had the same issue, dealer estimated $1300 to fix it. After watching this video, I added Blue Devil to my car, it fixed the leak.
I wont lie as a mechanic since i was 16 now that kinda gave me the fear ha ha maybe adding it after a clean and flushed oil change may have helped. have seen some snake oil stuff in my 30 plus years in the motor trade. but who knows?.
Hi Johnny, yes its scary to add such a substance to the oil, I had done loads of research beforehand and it is meant to be safe, hopefully I dont get leaks springing up all over the place after a few more days ha ha, so far so good the leak does appear to be gradually diminishing, as you say having a fresh oil change before use would of likely helped , I`ll give it a fair bit lot longer before I give some updates in the comments area to give it a fair chance, anyway thanks for the comment, mrix
By the way oil cooler leak are passenger side bellhousing.Having a om642 engine for 10 years i think ive got a self degree in the fuck ups merc made building it!
Hello, still no leaks to date fortunately, I am from the UK and this stuff was not the easiest to find, when I purchased mine the dealer only had a couple of bottles left, I purchased mine from Amazon uk..... mrix
6 Week Update - Hello all, its been about 6 weeks since I added the BlueDevil Oil stop leak and as of todays date the oil leak has actually stopped! it was such a really slow process as it took much longer than expected and far more miles before it did stop, maybe the oil cooler seal is much thicker than many seals so needed more time for the solution to react on it ? have no idea but it has actually stopped! this repair would of cost me anywhere from £1000 and £2000 so I am obviously extremely happy with the outcome, I will keep updating over the next months as it could start leaking again but all in all so far its happy days!, mrix
I tried this on my 2012 bluetec with the current rev. purple oil cooler seals. Didn't work at all. When I pulled them out the seals were split and ruptured. No sealant would work.
Hi, yes as you say if the seal are ruptured or split there will be no chance at all, if they are obviously warped, tried out there maybe a chance, my oil leak fortunately has stopped completely so for the price its worth a shot, did you manage to do the repair yourself or was it a pricey garage bill ? .... mrix
I have a 2007 sprinter and it started leaking A mechanic in Houston Texas counted me $3450 to change the oil cooler I think I'm going to give this a try first 🤷🏽♂️
Most definitely at least give it a try, it worked for me, well it has so far, once it worked its meant to be a permanent fix but we shall see I suppose, for the price nothing much to lose... it did take a couple of weeks for it to start working for me, those oil cooler caskets are quite think so this is why I think it takes longer.... all the very best of luck your end and hopefully it will help stop a very large garage bill as it did for me......mrix
Im commenting here again on my update. This really works. I used atp at-205 and now after a little over a month i have ZERO leaks, nada! Went from leaving fist sized puddle slowly to being no leaks at all. Oh and I poured 1,5 bottles into oil that had about 7000kms because I didnt think it would work.
Hi, so far so good but to be honest I am not really one for racing the car around, 70 mph up the dual carriageway is about it for me, I am just relieved it stopped a potentially expensive oil leak.
sorry i mean have you pushed the engine at times and still the same no leak? i dont mean you constantly race up and down just wanted to see how it performs under strains on real life driving
Im actually changing my seals this week,ive tried lucas oil leak stop and others but no good,do not put oil flush in oil change like i did to start this stupid oil leak.its removed gunk to cause the leak.also turbo needs changing so im going to be busy for 2 or 3 days as im a diy mechy not a pro because most pro mech ive asked to fix it have shit themselves and said no take it to a specialist! But your mechanics lads?? I couldnt palm my job off!. So il do it all myself and save a couple of grand.Mechanics these days are shithouses who all they want to do is change break pads or engine services!
Are you going to change the Oil Cooler seals ? if so its not something I would attempt but my hat goes off to you, I have just created another video on glow plug removal which can be a horror story if they snap off but I had luck on my side and plenty of penetrating oil.... mrix
Hello, its always worth a try I guess... however the first thing I would check is the turbo seal where the maff sensor joins to the turbo, its a very common leak where the oil leaks out and drain down the engine.. it can make it look like a oil cooler leak when its not etc.... all the best of luck...mrix
Hello. Thanks for your video. I have a question regarding my ml 350 bluetec 2013 which has a engine cooler oil leak. I was wondering if I can use this product for that purpose. If so do I pour Blue devil into the engine oil? Thank you in advance
Hello the question you have asked is the same reason why I used this product, I was told by the garage I had a engine oil cooler leak, the price to fix this on a V6 engine is very pricy, the cheapest I could find was £1200, likely f ar more expensive at the Mercedes dealer. I then obviously looked around for a cheaper fix hence trying this BlueDevil product, I had lost hope after a few days as it did not appear to work but its been a few months now and I no longer have a oil cooler leak, I never held out much hope for these products as I have tried them over the years and never had any success, so far so good, fingers crossed for a long term fix! but yes this product which looks like water you add it straight to the oil through the normal way you add oil by locating the oil filler on the top of your engine. You will need to use you vehicle for a few weeks to get a good idea if its been successful, best of luck mrix
Hello, do you still have the car? How is the oil leak? How is the helath of the engine? Have you noticed any bad signs after the use of the product? Thanks!
Hello, yes I still own the car, the car still runs fine but what I will tell you is to watch some of my other videos that relate to the turbo seal, I cannot be sure but many garages jump to the conclusion the leak is from the oil cooler which is a hugely expensive job to replace the seals, however I noticed that a lot of oil leaks from the turbo seal and leaks down the engine, this seal is a reletively easy fix so should be your first port of call first before going down the oil cooler leak. My garage told me I had a oil cooler leak but I believe it was the turbo oil seal where it connects to the mass air flow sensor.... all the very best of luck your end for a positive outcome... mrix
@@mrix just checked the turbo seal from your last video and at firt glance there is quite a bit of oil under there. I don't know if its enough to be dripping under the car, but its a good idea to change it anyway.
6 Months on - Hello all I am pleased to say after all this time the Blue Devil stop leak has cured my leak, nothing is leaking at all, no drips etc, I actually have proof as in my last two MOT prior advisories it shows I have a leak but after my latest MOT just a few days ago there is no longer a advisory, if you wish to check this out go over to the .Gov website and put in the reg LN13NKW and you can clearly see my car went through its MOT with flying colours... mrix
Hi Bri B, I am going to give it a little longer as I dont do much mileage and I want to give it a fair crack of the whip etc, its looking promising but the leak has not stopped completely, will get it worst again or improve ? I will give it another couple of weeks and create a update video of my findings as you say, thanks Bri, mrix
I have the same problem with my Alfa 159. Although the oil cooler is easy to access, seems to be a messy job to fix it on my drive way. Unfortunately I can't find BlueDevil. Is it so much different than other brands, like Wyn's for example? Worth a try?
Hi, I have no idea regarding other brand products as this was the first one I tried and it worked, it obviously worked for me but the seals on my oil cooler are rubber, it may also work for you also depending what seals you have, best of luck anyway ....mrix
To be completely honest I am not sure, it did work initially but after so many months I got a small leak back, after checking everything I noticed I had the usual turbo seal leak so this solution may of simply expanded the turbo seal ? I am sure now my leak was more the orange turbo seal.... check out a couple of my other videos as I dont believe now its actually the oil cooler seals, well in some cases its not... I highly recommend if anyone has a small leak to check that turbo seal which is a relatively easy to check and replace...... mrix
I have changed out the pcv and turbo inlet seal, they were both shot. I really dont feel like spending 1,5k-2k€ on oil cooler seals right now, just did abs unit fix, all 4 brakes, dpf, o2 sensor... the list goes on and on. @@mrix
Lets hope now knowing the turbo seal is shot it was that which was leaking / draining oil down through your engine...... I think you secretly enjoy these various fixes ?.... all the best mrix
I was told by the Garage it was the oil cooler which was leaking but if you check the turbo oil seal it was coming from there... its a very common oil leak on these cars but a easy fix, sometimes I dont think some of the garages are aware that its actually coming from the turbo oil seal and not the oil cooler.
Hi, for my engine it certainly took much longer than the time suggested, I initially did not think it would improve from when I made the video so never had much thought on it, however it seemed to gradually get better as the weeks moved forward, what the mileage was before it completely stopped I honestly don't know but many hundreds of miles for sure, as a update its still holding out, in fact I don't really think about it much anymore and seems to of stopped for good....... hopefully mrix
Initially I was not impressed but as the weeks moved on it did improve, this was a leak I had for 2 years so I am glad to say its now completely vanished, I also have proof if you check my reg on the .Gov site LN13NKW and the prior MOT`s show I have had advisories for a oil leak and this latest MOT just a week ago no longer advises there is a leak!, very happy as it would of cost me a small fortune to get fixed, so all in all its been brilliant for me, if its your oil cooler seal leaking its likely going to take a few weeks to work and not the few hundred miles they explain, mind you it depends on what mileage you do.... all the best mrix
Thanks for the video. How do you know its an oil cooler leak in the first place? I've got a 204 with an om651 engine that has been leaking for months, developing a patch like yours in the vid. Btw I couldn't find the BlueDev product you used, I think I might try Waynn's Engine Stop Leak.
Hi, in my case the garage told me it was a oil cooler leak which is apparently fairly common on these engines, I think this is the case as the oil cannot really leak from anywhere else, well so they think.... however even though my oil leak is cured I and not 100% sure if its from the oil cooler or the turbo inlet.... let me explained..... basically the PCV valve removes gasses from the engine which sent back into the turbo but there seems to be a design fault whereby it also pulls too much oil, I recently removed my Mas airflow unit which connects to each of the air filters and found a lot of oil leakage where it enters the turbo, this oil was also leaking down onto the engine and there was a fair bit of it, this is so common many owners tend to install a catch can which removes this excess oil. I cannot stress highly enough to check this first, its a easy job, just a few clips and a jubilee clip to loosen etc. If you do go through this process I would be very grateful to know if you also have this excess oil caused by the PCV Valve, just to note I purchased a brand new PCV valve which made no difference so for me a catch can is the only way to go with that side of things. When I say I was not sure if it was the oil cooler or the PCV Valve this is because I have removed the excess oil from the turbo area a fair few times now which could of also solved my problem but as I say I am unsure, anyway check that turbo inlet your end and see if you have oil leakage at that point.... all the best of luck.... mrix
@@mrix Thanks for the detailed reply. I actually had my rocker gasket replaced not long ago as they were wearing thin and leaking. As part of the job, my mechanic checked the oil seperator and it doesn't seem to be leaking. So I guess, like you said, it has to be the oil cooler. Its probably easier to replace that on my 651 compared to your v6 but I still wanna give that oil leak additive a try :)
Hi Ben, I suppose its not only about removing the parts but replacing them correctly with the correct torques and seals, I dont think its a job many would want to attempt, I suppose I would if I had my own work shop and all the necessary tools.... mrix

If you had the New style caskets installed I am wondering if your oil cooler is leaking or the turbo inlet is leaking ? please checkout my other video as it maybe not a oil cooler leak especially if you already have the New caskets fitted.
The turbo inlet with the orange seal leaks all the time its a hugely common issue with these engines, it leaks through and past the orange seal down through the engine, its very easy to remove and its certainly worth at least taking a look, I have made a couple of videos on this issue, the garage actually told me I had a oil cooler leak when I did not... if it is a oil cooler leak on yours its very strange as you have the New style seals already fitted... all the very best getting it fixed....mrix

The turbo inlet with the orange seal leaks all the time its a hugely common issue with these engines, it leaks through and past the orange seal down through the engine, its very easy to remove and its certainly worth at least taking a look, I have made a couple of videos on this issue, the garage actually told me I had a oil cooler leak when I did not... if it is a oil cooler leak on yours its very strange as you have the New style seals already fitted... all the very best getting it fixed....mrix
@@mrix I know I had this engine 3 times. The turbo inlet seal can leak but not so much that it drips under the car.
Hi Mate, you’ve got a abnormally long crank on cold starting. You might wanna check your glow plugs or glow plug controller. Cheers Drew
Hi Drew, yes it does tend to take around 5 turns first thing early morning but there is no warning on the dash or within the diagnostic tool ? do you think this could still be the case and its just a case its not got to a error stage ? , thanks ......mrix
It’s the non return valve in the high pressure fuel pump , cycle your ignition twice before starting bet it starts instantly
@@benjones1180 I was thinking the same, didn't even give the glow plugs time to warm up. It's at least 3 to 4 seconds where he started straight away.
