Happy new year everyone! I have been reading through your comments and it seems you all want more 651 content! Well note made, let me see what I can do! All the best to you all! Please subscribe if you havnt already as I would like a UA-cam plaque 😂😊
Now, this is content we love to see. I've got this engine in my S204. You showing us these common problems make us aware and just take an extra couple of minutes to check for leaks whilst doing the usual monthly fluid checks. Fab job Guys :)
the worst part about every SPR video is that you have to wait for the next one. Thank you so much for the information. I don't know how popular the OM626 engine is up in Britain but it would be greatly appreciated if you could get a video with that one.
Here is mine experience (car is 15 years old, C-class S204, 200CDI, OM651.913), currently at around 370.000km - Chain set + chain tensioner changed at 320.000km when i started to hear it - Inlet manifold changed at 310.000km (sooh accumulated) - Alternator refurbished at 350.000km - Brake calipers + brake caliper cylinders refurbished and steel brake lines replaced at 330.000km - Starter replaced at 350.000km (old one started to hear) - ESL steering lock - the worst part on this car - replaced for two times, at the end I put an emulator not to have problems with it any more (at 200.000km and at 360.000km) - Oil intercooler filter housing changed at 360.000km (preventive maintenance). This is the forth worst part on this car. - Oil injectors professionally refurbished at 320.000km and one replaced with OEM new Delphi on a next service (parameters were off and it kept sending a message "reprogram the injector on cylinder 2") - New Blower motor + Blower motor regulator (OEM parts) at 360.000km - Rear subframe at 320.000km (preventive maintenance, MB recall). This is the second worst part on this car, but I am protecting the whole bottom of the car with Dinitrol. - New Sachs shocks front and rear at 340.000km (front shock were also changed for the first time at 180.000km) - OEM battery died after 10 years, second one after 3 years and third will last max 4 years. Every new battery will lasts around 4 years max. Buy Varta, not OEM MB battery (Varta do this for them) because MB battery is not worth the quality - a lot of them die after 2-3 years. - Water pump - changed 2 times at 170.000km and 330.000km - this is the third worst part on this car. - All suspension arms and links are currently almost new on a car. - Engine mounts and transmission mounts are changed two times - ESP/ABS electronics was replaced once It was acceptable for me regarding the kilometers (most of the task were done after 300.000km) and my car is now ready for the next 200.000km without many worries. Maybe it is sweet spot to drive this car up to 300.000km, but if you like it with 5.000€ investment you will have another 200.000km without any big worries.
It irks me the amount of plastics used like the rocker cover I think most people would be happier to pay a little extra rather than plastic that goes brittle with age and causes leaks. Great informative vid as ever Sam.
Another very interesting and detailed video Sam. Always great content from you. Best Mercedes/AMG channel on UA-cam. Hope you get your plaque soon, you deserve it.
Hi Sam, another great and informative video. I had a E class 250Cdi as a company car new in 2013, Platinum Silver with a light gray interior, previously had two BMW 5 Series, but fancied a change. What a lovely car, smooth, quite refined and so economical trip average at 100k miles was 54.5 mpg! Had to have a new torque convertor under warranty at 84k, should have bought the car off the company really, but we had a new Jag E pace at home at the time. I totally agree with your ethos when having to strip down large parts of the car replace all you know that will for the future. Have you had to change many torque convertors on these cars, if I remember rightly it was something to do with a lock up clutch? 😀
Awesome video and one of your most informative ones! Especially for those who got a used c class like me because thats the only way they can afford to drive some kind of merc. Much appreciated!
My 651 E220 has 350,000 km on it, I've done the inlet manifold on it as it was cracked, the next job is the RC gasket and I might do the Tinning chain while it off. Great info for us mechanics and the DiY'ers alike. All the Best.
Hello. If you get 2 minutes. Can I ask how reliable are the 651. You heard alsorts. The main thing that’s stopped me buying one is the timing chain. I’ve heard there not very reliable and it’s fortune to get new chain replaced. Oh and yes please don’t stop the channel. I love it.
Taxi driver here... My 2018 om651 has 500k kms... everything on the engine is original exept for the dpf pressure sensor I maintain the car at half what Mercedes says
Bolting bits of plastic to a chunk of metal (engine block/heads) that is undergoing some extreme temperature changes from cold to hot and back while experiencing vibration is, imo, begging for trouble. Just another instance of the money people outvoting the engineering people. Not just MB, not just German makers, ALL manufacturers world-wide. Any potential fuel saving coming from the marginally lighter weight isn't worth the excessive cost of replacing these plastic bits.
They don't make any money on the car, don't forget that. If you want it all made from metal you'll have to pay for it. People don't want to pay for it I'm afraid
It's not just for weightsaving. For the last 15 years at least, all car manufacturers have to use as much recycled crap as possible. Parts, interior fabrics etc. Each manufacturer also has an average CO2 limit across their range and if they go over...they are fined. Not to mention fines for the elec cars they can't sell.
Superb video Sam as always but this one was special to me and probably many many others too... I have been praying for you to do this exact video, thank you. Yes, yes, yes, and yes please... can you do more on the 651... I am gutted you are not taking customers as I need the exact job doing to mine. Rocker and filter housing. I had the fuel filter housing done by a so called merc specialist in MCR area and every time I take it the bill is in the 1 to 2K area and everytime there are rookie mistakes... example. left the oil filler cap off 1st time... 2nd time left a fuel line off... my confidence has gone with him and I don`t know where to take it now.... I`m stuck with a massive oil leak and I just want my beloved OM651 to be right... I have spent a fortune trying to save it ... its a lovely 2010 estate S204 and my pride and joy. I've had suspension / brakes / gearbox / diff and many other things done and still cannot use it.... so yes please. I am going to have to do it myself if I can or find someone as good as you are.... Thanks a million for this video... Cheers..from me, Chris... BTW Can anyone recommend where to go near Manchester.. Sam your the No 1 choice..but alas mate !!!
Oil changes are the most important thing to do.. AND Change The ENGINE OIL MUCH MUCH SOONER THAN WHAT THE SERVICE BOOK SAYS.. AND THE DEALERSHIP SAY. YOU WILL NOT HAVE TROUBLE WITH YOUR ENGINE AFTER YOUR WARRANTY RUNS OUT.. Don't put your self in to the situation of buying expensive parts after the warranty runs out...
Hi sam another cracking video i would like more videos on the 651 engine across all variants would also be good i had a 2014 e250d with this engine and a 2017 gla 200d with the 651 but look completely different fuel filter on the gla is a clamp on the bulkhead rather than that cooler but the e class was same as you showed. Are there other differences ect. Also the gla is the engine just a detuned 220d or mechanical changes? Keep the videos coming out yes its time but they are good and getting better cheers steve
Thanks, great video! Please share more works on om651 engine. Any tips, tricks or particular tools how to remove stuck fuel injectors on these engines? Thanks
Had them stuck on the Sprinter. I'd do this 1 by 1. I've loosen the injector bolt half or full turn and drove until injector pops, then tighten it back, drive home and pull it out, engine MUST be hot. Sometimes they pop right away, sometimes it would take days, depending how stuck they are.
Another great video thank you mate. This om651 we have in many models they alright but if you look after you have. Personally i recommend change engine oil every 5-6k miles max. That’s for the engine condition and chain tensioner 😂all the best mate 💪
Great Video! I have recently had to go in twice to replace the oil filter housing and oil cooler (two separate leaks in the space of a year). Had I known this beforehand, I would have just asked them to change it all at once! Look forward to any other common OM651 issues as I plan to keep this car for as long as possible. Currently on 150k in a C250.
👍 - Great watch - Cost feels more palatable knowing that it'll likely run cleaner with the inlet carbon deposits cleaned-up - so not just a couple of oil leaks fixed! As for the plastic cam-cover - personally I worry more about the plastic sump! 😆
Great video again. I have a 2016 GLC with the 651 engine in it. It's only done 60000 miles and has been well serviced. Really useful to see you working on them and to look at what potentially can go wrong with them.
Another honest opinion and great video... get John on more often 😂 anything in the pipeline for the C220 w204 engine or even issues or buyers guide ? Great content as always from a local business👌👍
Ok, how many of you got up thinking someone was at the door 🙋♂️ 😂 Another informative vid 👍 I’ve not had a Merc in years, but still enjoy watching the channel.
Defo more vids on this engine. Got an old 55 plate W203 with this engine, its smooth but a little noisy when cold, still shes on 96k and almost 20 years old. Been well looked after so im a happy man.
thanks for a super vid. I am having a E 250 651 engine. When changing my filter housing --the new had 3 boltholes and the old only 2 Do you recommend to make a treaded hole for the extra bolt. ?? You had also 2 in this vid and 3 in the part. Regards Peter Denmark Happy viewer.
Manufacturers are forced to use recycled crap. Must have been like that for 15+ years unfortunately. A 30 year old W201, W124 etc etc engine will look miles different than current models with the amount of plastic being used.
The big problem in my mind is the fact these so called quality cars are becoming made of plastic and they expect people to pay big money for a new plastic fantastic Merc.. But on the positive side we have good honest mechanics like you to get people out of trouble 👍
Keep ‘em coming 👍👍 interesting Sam my 270 cdi has the same oil cooler problem makes hell of a mess from the gasket , shame your 2000 kliks away 🤣🤣 great videos
Happy New Years Sam✅ Top Job and that Carbon really clogs up the system You’ll be busier than ever with all of problems happening in Europe currently Cheers Frank👍
Very important to mention that you will get a new PCV with the rocker cover, which is a very common failure point. Especially on turbo charged vehicles.
Use to service sprinters 906/907 ect with the 651 , was pot luck if they sounded nice or rattled , even when serviced constantly , many way past 250k on the clocks, although, I can’t actually remember doing any oil filter/cooler housings 🤔 Did plenty of water pumps, fuel filter housing and rocker covers, inlet manifolds ( earlier ones ) . The occasional vacuum system when the water pump sleved half put coolant into the vac pump and filled every transducer/ change over valve with oil. Exhaust manifold studs snapping ( more on commercial than passenger OM651s mind ) Then the lovely 654 came out…..
Hi Sam What chemicals do you use for cleaning the oil and carbon from the parts? My favourite way is Mr.Muscle oven cleaner, pressure washer, brake cleaner and compressed air. This is obviously on parts that are not sensitive. One more thing: how would you compare the OM651 to OM646? Which one would you choose for reliability. Thanks for the video
I know this is not related to your latest video, but I’m thinking of buying a SLC. I know you’ve covered some stuff on SLK. Any particular thing to look out for a more interested in the 300 or the 43 SLC? Any little guidance would be very much welcomed. Keep up the videos. Absolute must watch the learn so much. 👍🏼👍🏼
Love you channel and videos. Really down to earth and informative. Do you ever work on the OM 646? I have an 08 nearly 160,000 miles and runs really well. Regularly get over 50mpg on work commute just on A roads. What’s your opinion on the engine? I look after it well, change oil every 6,000 miles which is twice a year.
@ Been from Devon to Yorkshire dales a few times and around France twice and again soon, never missed a beat. Hoping to see you working on one sometime.
Another good video Sam, I know yr a pro and the other guys, but looking at how compact engine bays are, have you ever done a job and forgot to put something back and had to strip down again
Johns a tidy mechanic 👍. Them 651s injectors can be a cunt to bleed ive airlock them before and had to get them sent off to be unlocked. Now i spend 10 mins bleeding them before i even connect the plugs😅
According to WIS injector bolts for OM651 engine on W212 should be 15 NM + 2 times 90 degrees. Tips and tricks getting out injectors easily on these engines and cleaning injector seats would get many views, I promise :) Also, do you regularly replace return line gaskets when getting injectors in and out? Nice content, thank you!
A healthy new year to all of you !!!. Yes more videos on this engine would be appreciated, I have a C250 diesel with this engine, absolutely love it, twin turbo gives performance with easy high 50’s MPG on a run, averaging 44 mpg. EGR valve etc you showed was heavily coked up, should it be regular cleaned ? Thanks.
Intakes are known for splitting on OM651s too, across their top seam / under the fuel filter housing. If you’ve got oil under the fuel filter housing there’s a good chance it’s gone. Listen for a boost leak that side. If you’ve got the EGR, throttle body and fuel filter housing off you’d be well advised to put a new intake on too (only around £150 genuine MB).
Worth keeping the injectors upright, I use a box with four holes. It can cause starting issues. Also nearly worth doing the intake manifold when doing the cooler.
@sprautos another trick that has had some success if the injectors have been out and are causing a non start is to take them out again and gently warm them up with a hot air gun, you can see bubbles of air come out in the diesel. Anyway great videos on MB vehicles👍
Great vid loving this new channel since the start, my 2006 c180k wont open doors today with either key fobs but starts once inside.....fuse 8 maybe in the boot..cheeky comment i know
It’s strange but it looks as if the accountants are back running companies finance and not the engineers. Poor material choices instead of the correct material. At least not as bad as Ford putting a timing belt in the oil pan! Many thanks.
Mercedes (and others) using plastics in engine parts subject to a heat cycle; and mixing coolant and oil through rhe same component separated by only a seal (that fails), requiring major work to repair, is several steps backwards compared to their older engines
Have you had any 654's in your garage recently? I have 160,000 miles on mine, and other than the DPF, it's been pretty reliable. I'm just wondering if I should expect any massive bills outside of regular services. PS, hit a pigeon recently, £1k for a new headlight 🤑
The parts that you are going to clean, is it possible for them to be cleaned while still in the car? For instance, using a product to clean as a preventive measure. Also, apart from the oil leak itself, are there any other signs that the gaskets/rings are on the way out? As ever keep up the good work..
Nice video, my 651 will be fixed in couple weeks for the rocker cover leak, i'm now going to ask if they replace the cover also or they just wanted to change te gasket
Happy new year everyone!
I have been reading through your comments and it seems you all want more 651 content! Well note made, let me see what I can do!
All the best to you all! Please subscribe if you havnt already as I would like a UA-cam plaque 😂😊
The plaque dont matter.. you already double platinum in these streets ❤
A series of videos on the 651 would be a great resource for owners and mechanics alike.
Populate engine so let’s see what we can do. 📺
Sounds good.
101%
Now, this is content we love to see. I've got this engine in my S204. You showing us these common problems make us aware and just take an extra couple of minutes to check for leaks whilst doing the usual monthly fluid checks. Fab job Guys :)
the worst part about every SPR video is that you have to wait for the next one.
Thank you so much for the information.
I don't know how popular the OM626 engine is up in Britain but it would be greatly appreciated if you could get a video with that one.
Here is mine experience (car is 15 years old, C-class S204, 200CDI, OM651.913), currently at around 370.000km
- Chain set + chain tensioner changed at 320.000km when i started to hear it
- Inlet manifold changed at 310.000km (sooh accumulated)
- Alternator refurbished at 350.000km
- Brake calipers + brake caliper cylinders refurbished and steel brake lines replaced at 330.000km
- Starter replaced at 350.000km (old one started to hear)
- ESL steering lock - the worst part on this car - replaced for two times, at the end I put an emulator not to have problems with it any more (at 200.000km and at 360.000km)
- Oil intercooler filter housing changed at 360.000km (preventive maintenance). This is the forth worst part on this car.
- Oil injectors professionally refurbished at 320.000km and one replaced with OEM new Delphi on a next service (parameters were off and it kept sending a message "reprogram the injector on cylinder 2")
- New Blower motor + Blower motor regulator (OEM parts) at 360.000km
- Rear subframe at 320.000km (preventive maintenance, MB recall). This is the second worst part on this car, but I am protecting the whole bottom of the car with Dinitrol.
- New Sachs shocks front and rear at 340.000km (front shock were also changed for the first time at 180.000km)
- OEM battery died after 10 years, second one after 3 years and third will last max 4 years. Every new battery will lasts around 4 years max. Buy Varta, not OEM MB battery (Varta do this for them) because MB battery is not worth the quality - a lot of them die after 2-3 years.
- Water pump - changed 2 times at 170.000km and 330.000km - this is the third worst part on this car.
- All suspension arms and links are currently almost new on a car.
- Engine mounts and transmission mounts are changed two times
- ESP/ABS electronics was replaced once
It was acceptable for me regarding the kilometers (most of the task were done after 300.000km) and my car is now ready for the next 200.000km without many worries.
Maybe it is sweet spot to drive this car up to 300.000km, but if you like it with 5.000€ investment you will have another 200.000km without any big worries.
Great Vid… I own a 2012 C Class with the 651. I do all the maintenance so more vids on this engine would be great. Thanks for the work
+1
It irks me the amount of plastics used like the rocker cover I think most people would be happier to pay a little extra rather than plastic that goes brittle with age and causes leaks. Great informative vid as ever Sam.

Please make a video of OM651 timing chain replacement.
Thanks!
My 651 E220 has 350,000 km on it, I've done the inlet manifold on it as it was cracked, the next job is the RC gasket and I might do the Tinning chain while it off. Great info for us mechanics and the DiY'ers alike. All the Best.

There not bad, chains can wear anywhere from 100,000 miles - 200,000 miles depends if the car has been serviced correctly using proper oil and filter.
@ hi. Thank you for taking the time to get back to me. I really appreciate it.
Taxi driver here... My 2018 om651 has 500k kms... everything on the engine is original exept for the dpf pressure sensor
I maintain the car at half what Mercedes says

Lovely propper clock on dashboard
Bolting bits of plastic to a chunk of metal (engine block/heads) that is undergoing some extreme temperature changes from cold to hot and back while experiencing vibration is, imo, begging for trouble. Just another instance of the money people outvoting the engineering people. Not just MB, not just German makers, ALL manufacturers world-wide. Any potential fuel saving coming from the marginally lighter weight isn't worth the excessive cost of replacing these plastic bits.
They don't make any money on the car, don't forget that. If you want it all made from metal you'll have to pay for it. People don't want to pay for it I'm afraid
It's not just for weightsaving. For the last 15 years at least, all car manufacturers have to use as much recycled crap as possible.

I find watching you trying to do the intros very entertaining & good on you for leaving it in .
Cheers Tom, yea it’s worth leaving as is makes it’s more human as you can all relate
@ yeah definitely, there’s lots of nice little touches throughout your videos.
Brilliant video and information, for sure this format is a winner, thank you and your team at SPR, looking forward to a brilliant 2025 watching you.
Another great video thank you mate. This om651 we have in many models they alright but if you look after you have. Personally i recommend change engine oil every 5-6k miles max. That’s for the engine condition and chain tensioner 😂all the best mate 💪
Totally agree
Mate, costing - one of the most exciting parts of your video. But I'm fully satisfied with your professional approach
Sam, hope you had a good holiday with your family. Fantastic video as always.
Thank you 🙏
Another great and informative video Sam and crew keep up the great work 👍🏻

Great work AGAIN boys keep up the good work your videos are brill 🇬🇧👍🇬🇧👍🇬🇧
Owners must remark about the before and after difference on this job. I would imagine it is night and day.
Great video again. I have a 2016 GLC with the 651 engine in it. It's only done 60000 miles and has been well serviced. Really useful to see you working on them and to look at what potentially can go wrong with them.
Another honest opinion and great video... get John on more often 😂 anything in the pipeline for the C220 w204 engine or even issues or buyers guide ? Great content as always from a local business👌👍
Sam, your should add a "While you're in there..." tee shirt to your merch shop 🙂
Yea I think I should, need someone to design it for me
Great job 👏 John
Ok, how many of you got up thinking someone was at the door 🙋♂️ 😂 Another informative vid 👍 I’ve not had a Merc in years, but still enjoy watching the channel.
Glad you enjoyed it
Defo more vids on this engine. Got an old 55 plate W203 with this engine, its smooth but a little noisy when cold, still shes on 96k and almost 20 years old. Been well looked after so im a happy man.
thanks for a super vid. I am having a E 250 651 engine. When changing my filter housing --the new had 3 boltholes and the old only 2
Do you recommend to make a treaded hole for the extra bolt. ?? You had also 2 in this vid and 3 in the part.
Regards Peter Denmark Happy viewer.
1800£ for what you done and changed it's not a lot at all,great video as always ❤
Making oil retaining engine parts from plastic is extremely daft. Neearly as daft as 'deleting' dip sticks.
Manufacturers are forced to use recycled crap. Must have been like that for 15+ years unfortunately. A 30 year old W201, W124 etc etc engine will look miles different than current models with the amount of plastic being used.
Agreed 👍
Thanks for saying that, I commented the same thing, they are just being cheap, and it's costing
you owners tons of money.
Plenty of service parts sales
Great job! Thanks Sam, another good video 🙏
A great channel to watch, your effort and knowledge is much appreciated, just wanted to say that i really enjoy watching and learning. Many thank.
Brilliant vid thank you and yes please definitely more on this engine.
I am so admirative of you expert mecanics able to handle those important engine jobs.
Top video would love to see more work done on this engine and always Good to see you breaking down the cost 👍
Another very informative video, thank you again. I really liked my W204 C220 - nice and torquey.
I have a 2013 W204 with the 651, so would like to see more videos on it. No oil leaks on my car so far, so thanks for the info on parts
Cheers, mate, great video once again, my knowledge of Mercedes cars is defo getting better
Good to see you again Sam. Happy New Year.
Brilliant video yet again, Sam.
The big problem in my mind is the fact these so called quality cars are becoming made of plastic and they expect people to pay big money for a new plastic fantastic Merc..
But on the positive side we have good honest mechanics like you to get people out of trouble 👍
OM651 timing chain tensioner, timing chain, sprockets, guides and guide pins plus oil pump replacement video please
That would be a good one
Giving me nightmares after changing OM651 engine in my sprinter last week. Seems a decent engine if maintained properly.
More om651 videos :D!
Keep ‘em coming 👍👍 interesting Sam my 270 cdi has the same oil cooler problem makes hell of a mess from the gasket , shame your 2000 kliks away 🤣🤣 great videos
Can you do a video on oil dilution on this engine please
How would you recommend cleaning off the carbon? Thanks. ❤
Happy New Years Sam✅ Top Job and that Carbon really clogs up the system
You’ll be busier than ever with all of problems happening in Europe currently
Cheers Frank👍
Very important to mention that you will get a new PCV with the rocker cover, which is a very common failure point. Especially on turbo charged vehicles.
Very good point 🙏
Use to service sprinters 906/907 ect with the 651 , was pot luck if they sounded nice or rattled , even when serviced constantly , many way past 250k on the clocks, although,
I can’t actually remember doing any oil filter/cooler housings 🤔
Did plenty of water pumps, fuel filter housing and rocker covers, inlet manifolds ( earlier ones ) .
The occasional vacuum system when the water pump sleved half put coolant into the vac pump and filled every transducer/ change over valve with oil. Exhaust manifold studs snapping ( more on commercial than passenger OM651s mind )
Then the lovely 654 came out…..
Your right you get some that sound sweet and other that sounds like a black cab taxi
Thanks Sam keep the videos coming please.
Great information! I've heard so many mixed things about this engine, I'm not a big fan of this era's mechanicals. Too much plastic.
These vlogs are really helpful. 👌
Nice video
Keep them coming
Happy new year
Anything om651 car or engine will be great i own a c250 w204 cdi on a 14 so will definitely be interested to see any work on these.
Hi Sam
What chemicals do you use for cleaning the oil and carbon from the parts? My favourite way is Mr.Muscle oven cleaner, pressure washer, brake cleaner and compressed air. This is obviously on parts that are not sensitive.
One more thing: how would you compare the OM651 to OM646? Which one would you choose for reliability. Thanks for the video
Good work 👍🏾
Cleaning an egr valve is always a satisfying experience 😊
Your right
I know this is not related to your latest video, but I’m thinking of buying a SLC. I know you’ve covered some stuff on SLK. Any particular thing to look out for a more interested in the 300 or the 43 SLC? Any little guidance would be very much welcomed. Keep up the videos. Absolute must watch the learn so much. 👍🏼👍🏼
Just the one i was waiting for . great video!
Love you channel and videos. Really down to earth and informative. Do you ever work on the OM 646? I have an 08 nearly 160,000 miles and runs really well. Regularly get over 50mpg on work commute just on A roads. What’s your opinion on the engine? I look after it well, change oil every 6,000 miles which is twice a year.
646 was a cracking engine better than 651!
I have one in my Vito .
@ Been from Devon to Yorkshire dales a few times and around France twice and again soon, never missed a beat. Hoping to see you working on one sometime.
Another good video Sam, I know yr a pro and the other guys, but looking at how compact engine bays are, have you ever done a job and forgot to put something back and had to strip down again
Oo yes of course, one little distraction is all it takes
Happy new year , let’s get to 100k subs this year🔥💪🏻
Yes please! 🤞🏻
Johns a tidy mechanic 👍. Them 651s injectors can be a cunt to bleed ive airlock them before and had to get them sent off to be unlocked. Now i spend 10 mins bleeding them before i even connect the plugs😅
Can’t they just!
According to WIS injector bolts for OM651 engine on W212 should be 15 NM + 2 times 90 degrees. Tips and tricks getting out injectors easily on these engines and cleaning injector seats would get many views, I promise :) Also, do you regularly replace return line gaskets when getting injectors in and out? Nice content, thank you!
A healthy new year to all of you !!!. Yes more videos on this engine would be appreciated, I have a C250 diesel with this engine, absolutely love it, twin turbo gives performance with easy high 50’s MPG on a run, averaging 44 mpg. EGR valve etc you showed was heavily coked up, should it be regular cleaned ? Thanks.
Your videos are always interesting. Would love more M271 content. 🙂
Intakes are known for splitting on OM651s too, across their top seam / under the fuel filter housing. If you’ve got oil under the fuel filter housing there’s a good chance it’s gone. Listen for a boost leak that side. If you’ve got the EGR, throttle body and fuel filter housing off you’d be well advised to put a new intake on too (only around £150 genuine MB).
Your right
I like this video but it didn't make me wanting to replace my OM648 car with OM 651. 😀
Please continue with om651 service work.
Those 651 engines are always a pain to start up, I got scared my first time doing a major job because it struggled to start and would die out
Great content btw, have an older version of that engine
3lt v6 CDI please? and or 3.5 lt v6 petrol please!!🙏
Worth keeping the injectors upright, I use a box with four holes.
It can cause starting issues.
Also nearly worth doing the intake manifold when doing the cooler.
I’ve heard to stand them up a few times going to donit next time round
@sprautos another trick that has had some success if the injectors have been out and are causing a non start is to take them out again and gently warm them up with a hot air gun, you can see bubbles of air come out in the diesel.
Anyway great videos on MB vehicles👍
Great vid loving this new channel since the start, my 2006 c180k wont open doors today with either key fobs but starts once inside.....fuse 8 maybe in the boot..cheeky comment i know
Worth a try pull it out check it out it back In
It’s strange but it looks as if the accountants are back running companies finance and not the engineers. Poor material choices instead of the correct material. At least not as bad as Ford putting a timing belt in the oil pan! Many thanks.
What was ford thinking !?
Ford Peugeot Honda they all deserve a 💩@@sprautos
Mercedes (and others) using plastics in engine parts subject to a heat cycle; and mixing coolant and oil through rhe same component separated by only a seal (that fails), requiring major work to repair, is several steps backwards compared to their older engines
Yup, and I thought my W124 was complex. Not compared to this plastic thing.
excellent, i wait for other videos on the OM651
Carbon is brutal on tha thin!!!😮
Would enjoy a series for 651, got me a w205 with it. :)
Have you had any 654's in your garage recently?
I have 160,000 miles on mine, and other than the DPF, it's been pretty reliable. I'm just wondering if I should expect any massive bills outside of regular services.
PS, hit a pigeon recently, £1k for a new headlight 🤑
Hi Sam! Nice video! Could tell what kind of grease is that you use on the injectors? Thanks!
The parts that you are going to clean, is it possible for them to be cleaned while still in the car? For instance, using a product to clean as a preventive measure. Also, apart from the oil leak itself, are there any other signs that the gaskets/rings are on the way out?
As ever keep up the good work..
As for the cost.....with age and mileage It'll probably only have it done once in its lifetime so that's a fair price with the add ons it receives.
Nice video, my 651 will be fixed in couple weeks for the rocker cover leak, i'm now going to ask if they replace the cover also or they just wanted to change te gasket
Just a preference of ours, if they don’t there not doing it wrong 😃 we give the option
Another brilliant video, but 651 doesn't mean anything to some people. Typically what car would this engine go in?
A , CLA, B, C, E GLA, GLC , GLE Vito, sprinter, most Mercedes
Don't knock the old Transit. They went on and on and on. Until the body fell to bits😅😅
