My M156 (2009 w204 C63) is approching 180 000km and it still has the factory old style headbolts, cam adjsters, cams, lifters, PCV and injectors. It runs like a champ, no rattle noise at start-up. It likes to consume oil, that's true (around 0.5L per 1000km). Frequent oil changes and filters are mandatory to keep the engine happy. I wait 20-30min until the oil is fully warmed to go over 3000rpm. I plan to do the injectors soon anyways.
😎 good job staying on top of the maintenance! We’re at about the same mileage. I have injector DIY video in case it helps ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-qBO-tMAVM08.html
Your frequent oil changes and monitored driving under 3k prior to operating temp is helping you big time! I do the same with my M157 and M278 engines. When starting cold, I like to let idle for 3min before throwing into gear.
W123 OM616 240D Does NOT need any of that stuff replaced that you mentioned. 700.000 miles. I have a 1995 Toyota Tercel with 1.5 5E-FE and at 450.000 miles still has ORIGINAL INJECTORS wheel bearings ball joints tie rod ends alternator starter fuel pump brake master cylinder Clutch master and Slave
Changed to LiquiMoly Molygen 5w-50 oil and the additive recently. Amazing how quiet and smooth my M156 is now. I was skeptical about the reviews , but I am impressed.
@@AccentOnCars Temps are never high on my engine. I have used LiquiMoly 10W-60 and Lubegard since I have owned it back in 2017. I think the Molygen has high tungsten content. One reviwer went 8500 miles cabbing in CHicago, and stated there is no smell to the oil. Still very slippery to the touch. I have an SL63AMG 2009. Great Tips!
2009 CLS 63 AMG 114,000miles....runs like a Champ....3,000 mile Oil Change every time with some Motorkote...along with a Renntech tune, secondary cats & resonator removed she growls lika panther.....!
Absolutely right! Every 3000 miles without fail. Have been doing this for years across a wide range of high performance cars. Have never had a failure. My low mileage 156 and 157 powered cars, every 3000 miles or annually , at a minimum.
Your input on the rpm rate and oil pressure is genius. Makes so much sense considering these motors suffer from top end lubrication issues. So simple yet never thought of it. Thank you!
Great video. Congrats on the milestone. Excellent advice for getting your engine 7k rpm (after proper warm up). Not only does it help keep the engine clean but it keeps you smiling😊. I never liked the comfort setting of the transmission. 90% of the time I keep it in the sport setting.
Got a 2014 C63 w204 with 90.000 km, bought it with 82.000 km. The previous owner already changed the cam adjusters and lifters, during my 8k km so far I already had one injector stick open when I gave it some properly hard driving. That lead to the engine running weird at first, then not starting at all with a terrible noise. I was lucky though, didn't get hydroblocking and after a new injector as well as spark plugs and oil, the engine was as good as before.
Glad it didn’t seize up, man 👍 The adjusters and lifters on 2014 year are the revised ones with slightly better qualities. It should not need replacement at that mileage. Follow the oil related recommendations I gave in the video.
@@AccentOnCars Yeah, they got replaced under extended warranty. Just like rest actually. Yeah, using 5W40 Ravenol and changing it at least every 5.000 km anyways, until now even more frequently in fact. Thanks for your advice and the video 👍🏻
I have a 2001 clk 55 m113 eng. 140k miles. Bulletproof eng and trans. Full synthetic Penzoil advantage every 5k miles and full synthetic trans fluid every year regardless of miles. Runs unbelievable 👌
I know that engine very well! Reliable indeed. Aside from oil leaks it’s solid (but leaks happen to all old engines). I would still recommend the same as in the video. Changing plugs is twice as expensive on yours as I believe you have two for each cylinder, right? 🤝
@AccentOnCars yes I do. I changed them at 100k miles w iridium ngk. That freak pressure plug port is definitely leaking w the copper crush washer. Difficult to get to so I didn't do it when I did the oil cooler seal job
My W204 c63 has done 122k don't have any issues touch wood. I change my engine oil every 2k miles and I let my engine warm oil till its 80c before I let the rev gose over 2000rpm I've replaced all my injection and changed the pcv valve. Look after that engine will never let you down
Awesome video Sir, subscribed! I too have a Merc with M156 engine and wish to keep it running forever as I plan on never selling it. Do you add the Ceratec AND Mos2 engine treatment together? Many thanks
Thank you for your support 🤝 I switched to MotorKote for additives. When using LM, you don’t want to use Ceratec and MoS2 at the same time. You should alternate. You can add ceratec every 2-3 oil changes, and use mos2 in between.
Nice video thanks !!! I'm 156 owner and I tend to agree with what you've said!!! But especially regarding to revving I wonder how much mechanically based this is!
I am no mechanic at all, lol 😂 Just an m156 enthusiast with healthy engine (thanks God). I can only do occasional repairs like head bolts, injectors, brakes, steering and suspension links, etc. My DIY playlist lists them. 🤝
My 07 E63 is at almost 130k miles, I have only owned it for around 10k. It has been great, all I have had to do is motor mounts. I really hope I wont have to do cams and lifters anytime soon. The previous owner said he had the valve covers changed and everything looked good at some point fingers crossed. The head bolts also haven't been changed to my knowledge.
Very good video. Thank you for sharing. Unfortunately my headbolts failed at 50k miles. Other than that everything has been flawless. Ill need to inspect cams soon though
Thanks! I switched between LM Ceratec and MotorKote and saw lower temps with MotorKote. I still use MoS2 sometimes although I get higher temps. I will stick with MotorKote. A friend recommended it to me. I was sold finally sold on it after watching this video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-88vwUwa3igQ.htmlsi=rKaMzrU0NqC6AZXy
no brother i have 2010 s63 83000 miles i agree with you make clear sense simpl i used to do my s500 s550 oil changes every 5k transmission every 40k but ima do every 3000 miles and what about transmission how often you recommend doing it? i dont care about the cost my guy is cheap and all genuine and this cars if u r cheap then dont even buy it even if you have the money to buy it dont buy it! lol
Wanna make it bulletproof? Find a solution to run lower oil temperature. Continuous 110-120 °C is eating the engine slowly. Not to mention that you cannot hillclimb more than 5 minutes full throttle before it reaches 140°C. I am still looking to find a solution to that, so if you know one pls let me know. The rest is BS.
great info.. any tips for my 2010 ml m273 5.4 liter ? noticing oil smell inside the cab from time to time .. wondering if the catch can would help with this
Yes, transmission service is due every 40k miles or 60k km. But even doing that didn’t save me from the speed sensor failure built into the conductor plate. I replaced the conductor plate + valve body 😀 I have stock pan.
I assume you talk about m156? Slightly improved design for the adjusters and better coating for the lifters (you should consider buying black series lifters with black coating on top). You can buy adjuster plates and rebuild your adjusters to save money.
Yes, definitely. Some additives can lower temps by a few degrees celcius by reducing friction slightly, but the engine will reach normal temperature. M156 especially runs hot.
Interesting remark you made about the oil pressure. Did you actually measure the pressure? When driving here in the netherlands it is often around 1200rpm. I have an E63, as well as an E500 M113. Can’t ready the oil pressure while driving
My 722.9 shifted into 7th unexpectedly after rolling up to 120 from 40 in 2nd. Could that be due to oil starvation? 2016 E63S M157 with 55k mi.. I also got a check oil level - add 1 qt when driving in 1st and 2nd only in a 25 mph zone. I just changed my trans even though the dealer did at 45k as well as the rear diff. I'll do my front diff during my next oil change with the trans fill adapter. Also, I think I spotted a front diff and/or coolant leak. My coolant resevoir is definetely not holding up. I'll know if I'm screwed once my oil comes out all milky but I'l keep topping it off until then
Funny I am working on 722.9 maintenance video at the moment 😎 You should have a 7 speed MCT transmission in your 2016 E63S. I don’t believe it would go all the way up to 120 mph in the second gear. It will be in 3rd or 4th gear during hard takeoff. But if you lift off and coast for a bit it will go into 7th. If it acts up again, I’d say get it diagnosed for any codes, fluids, etc. It’s always a good idea to service it regularly per manufacturer specs. Check your engine oil level and keep it at the max mark. M157 burns oil. The best thing you can do for m157 is to disconnect the oil pump solenoid. Watch this video ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-MuZJSGN8qZ4.htmlsi=p8Ipgaziuby8m9Jc
Yes I was in manual and most likely in 4th AWD sport config. at that speed but it was as if the car just went into limp mode at above 100 mph like a safety feature. As for codes, it read P2610 (Engine ECM/PCM Engine off timer performance), P0120 (Throttle/Pedal Position Sensor Circuit A), and P2377 (Turbocharger Pressure Inlet Sensor)
You can use car sales websites such as cargurus, autotrader etc. to see what they sell for in your State and nationwide. Someone I know recently sold their E63 with less than 50k miles for $30K. I think yours should be around 20 or so but again, check the market. Also depends on the car and how much you are ready to pay for it
I usually wait until the oil temp reaches 40C at least and then start driving slowly. I crawl slowly at first and then drive it normally but very smoothly. The 7g rushes to higher gears so you don’t go over 2k anyway. I don’t drive it spiritedly until the oil is at least 90c.
