COMMON MERCEDES OM651 CDI OIL LEAKS! + EXTRAS WHILE WERE IN THERE! HOW MUCH!?

[@sprautos]

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 KZbin plaque 😂😊

Today we're performing a resection of the upper right quadrant of this patients liver. While we're in there the pancreas is also going to be looked at, and the Whipple procedure either full or partial considered.

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

[@arismidos4326]

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.

[@Wrenny-c2j]

Another great video , and detailed description of all jobs undertaken. The best/worst bit is when you tell us the cost to the customer. I am fortunate enough that I can do all my own maintenance work and repairs so although the prices always seem high , I always enjoy the fact that I can tell the missus how much I’ve saved . And then spend my savings on more tools that I don’t need 😂😂

[@darrenmartin4014]

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.

[@comaradelee]

in taiwan, they make aftermarket covers and other common plastic parts into steel/aluminum parts.

[@clear-vision]

For the last 5 years, I've owned a 2014 AMG Sport e 220 with the 651 engine. I've had it serviced regularly. It's very quiet with plenty of torque for overtaking, a real joy to drive. The only issue has been an intermittent fault with an LED rear light which meant replacing the whole unit. What was wrong with the old lights, you could just replace a bulb? I would definitely recommend owning one that's been looked after. Well done SPR, please keep the 651 videos coming.

[@nigelgreer5400]

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 :)

[@DonKrik-n9y]

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

[@eurodude79]

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.

[@karlmabe1649]

Lovely propper clock on dashboard

[@TheGT73]

My 2010 E220 is on 163k miles and needs these jobs doing. I want to keep the car at least another 5 years so will be investing in the required maintenance in the coming months. Apart from regular maintenance my only other repair has been a coolant pipe replacement. Not bad for 3 years and 40,000 miles in my ownership. More OM651 content please!

[@Dave-Huston-Dublin]

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.

[@sprautos]

Good going

[@RetroClinic]

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.

[@sprautos]

Glad you enjoyed it

Great video! We’d love to see more content on the OM651.❤

[@overthehill1986]

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

[@OK247OK]

If I ever by a Merc ,I would use SPR Professionals at work

Have you ever had the valve cover bolts come loose on these engines?

[@patrykcholewinski7164]

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 💪

[@sprautos]

Totally agree

[@RaymondParkin-f3z]

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.

[@HarveyDhillon-o2o]

More videos on the om651 engine please

[@mmaiolo]

Great video. So clearly explained and I’ll need to do this same job on my car. Did you need to replace any vacuum hoses/fittings or the like?

[@IfanSJones]

👍 - 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! 😆

[@davidevans1266]

More videos on the 651 please, do you recommend changing the water pump and its housing, whilst you're draining the coolant on cars over 100000 miles? Thanks

[@andrewtodd126]

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

[@JasonPen926]

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.

[@Brisbane-h9h]

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...

[@shafqatahrarjaigirdar9562]

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.

[@ChrisPatrick-q6k]

Oil filter housing leak is a bit BMW. I like Grieg, seems genuine.

[@MarkG-m4p]

[@shiveshgupta3333]

Please make a video of OM651 timing chain replacement. Thanks!

[@georgedaville4662]

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? 😀

[@y0jimbb0ttrouble98]

Happy New Year SPR. Great video and perfect opener for 2025. Sam, I have the exact same issues with my 2010 S204 M271 CGI. Can I assume that both the rocker cover and fuel filter housing need replacing as in the vid ?

[@wolfgangezeh5021]

Sam, hope you had a good holiday with your family. Fantastic video as always.

[@sprautos]

Thank you 🙏

[@blueangelstudios]

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 !!!

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.

[@sprautos]

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.

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.

[@SH-vb5ph]

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).

[@sprautos]

Your right

[@user-vc5qc5lc8u]

I am so admirative of you expert mecanics able to handle those important engine jobs.

[@unclepeanut15]

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

[@harveysmith100]

Just subbed. have you done a video on the OM651 timing chain. Is it an engine out job?

[@sprautos]

Thank you 🙏 Not yet, but if guide arnt knackered can leave engine in and just do chain and tentioner if not engine out

[@harveysmith100]

@@sprautos Many thanks for getting back to me.

[@catalinvoiculescu5327]

In the end, you blocked the injectors. In the OM 651 version with Delphi injection, there is a typical procedure for venting the ramp and injectors. You do it with the "Star". at 2000 rpm for 1 min. Never let it idle immediately after it starts. You block the injectors with air. This happens at Delphi. You only unlock them on the test bench injectors, stupid work. The biggest mistake at Delphi is to use the automatic until it starts, like you did. If you aired it properly, it would start at a quarter. Keep in mind for the future!!

[@roderickjones7479]

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..

[@Blondie5791]

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]

I’ve heard to stand them up a few times going to donit next time round

[@Blondie5791]

@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👍

[@ryancunningham2850]

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…..
