Hi all, very excited to talk about these engines, while these comparisons can be subjective, please feel free to add more and make correction in the comment section so others also can use your valuable experience and knowledge. Please like and share so this video can be seen by more Benz Addicts, Cheers Max ;)
Thankyou very much..just purchased one with the 112 engine..I am working on bringing back to a good state of health after being neglected by previous owner...Your channel has helped alot...again thankyou very much..
Thanks, glad it is being helpful 😊
I’ve a M112 jdm here Canada 🇨🇦 love it never let me down
Lovely engine, so smooth and torquey:)
bruh its german, not JDM 🤦♂
Great video with tons of info! Don't forget the 5.45L(5.5L) M113 that was stuck in the CLK 55's! They made 362hp-367hp(Probably more in the later years where changes were made but the power changes weren't put down on paper completely).
Thank you, Great point. We limited the topic to non-AMG variants :)
Thanks for the effort Maxi joon ❤🙏
You are welcome 😊
I went for the M112 in the W211. Because the M272 have the balance shaft/chain and inlet manifold problems that may occur. Not all have the problem but i did not want to take the risk.
The other problem i know besides the valve cover leaks on the M112 is the harmonic balancer.
The highest displacement of the M112 is a 3.7 found in the W220 S-Classe as a S350.
Thanks for the correction, Yes, 3724cc is the highest displacement for M112 and it makes 249HP.. such a shame they did not use it in W209.
M119 enters the chat, Hold My Beer.
Would be a winner in many ways, reliability, ease of maintenance...
Not really. Engine harness, chain guides, etc
You hit the nail on the head in your conclusion. Older are more reliable in general, but newer are better in most every other way. I had a m113 05’ for three yrs and M273 10’ for 1 yrs. Both of their issues are well known. I experienced these well known issues on both engines. My M113 gave me overall less issues, but at 150kmiles it had a slight tick that could be heard when the window was down and it needed a quart of oil between changes. The M273 on the other hand at 150k miles I’m tracking down a code-less misfire (current theory) requiring $$$ in parts with crossed fingers. But when she is running smooth, I’ll take the M273 any day!
Yes, generally more power, less fuel consumption = more complexity and less reliability. There should be a sweet spot. Toyota / lexus might be the only car manufacturer that gets it right these days...
Agreed. Although I’ve been hearing rumblings that even Toyota’s latest products are letting go of reliability to achieve the latest eco/power goals. Time will tell.
@KM-bv3fp who knows, only time would prove.
Great video Max. Love the M112/M113. Just wish they have a physical dipstick, otherwise the reliability is great!
Nekem van m113, és van nívó pálca
Thanks Serge, I wish it had the Dipstick too.
👍
mine has got one. M113 W220 99
Very interesting comparison. My 2006 cubanite silver CLK 280 coupe has the newer four cam shaft M272 engine with a seven speed auto behind it. Love CLK. Main issue I have had with it: is finding a mechanic that really knows older Mercedes and is actually willing to fix it in Canberra. Two ignition coils replaced in past year and I keep a spare in boot for NRMA to fit if another goes. At 139,500 Ks I do not have any cam chain, engine balance shaft issues. My car was made at Bremen, Germany. Where was your M272 engine made? If Mexico or USA that could be the source of the batch of bad balance shafts. Keep up the great content and explanations. Cheers Scott
Hi Scott, thanks for great comment, according to Wikipedia: "M272 engines that were sold between 2004 and 2008 with engine serial numbers below 2729..30 468993 often show early wear of the balance shaft gears," you can find your engine number by putting your VIN number on a website that you can google, I am also making a video on how to test these....
Essential to use a mechanical shop that has actual experience performing all difficult repairs on your engine, transmission, chassis. I’m in Sydney and the shop I use has mature ex MB dealership trained mechanics (mostly during their apprenticeships). It inspires confidence if you can ask: do you have any replaced M272 balance shafts around to show me? Good luck finding an appropriate shop. Btw, my W211 350 was made at the main Sindelfingen factory in 2005-according to the decoded VIN from the site: LastVin
@Michael.Chapman Thanks Scott, good points.
Thank you for this Very informative. I am looking to buy soon 2004 thru 2008 Chrysler crossfire they have the M112 engine. It's very good to know they are reliable engines thank you.
Good to know that Chrysler had used M112 :)
The Xfire (M112) used a dipstick in every model year (2004-2008). I was not even aware that some M112-engined cars lacked them. *Does anyone have a list of the M112 cars which didn't have a dipstick?*
Thank you for a great video. I own a W211 M272 built 2005. It has done 108,000 km. I’ve had check engine lights three times: to replace catalytic converters, thermostat and the entire intake manifold (tumble flap). Re the defective tempering of the balance shaft’s toothed drive cog; is it your understanding that not all M272 engines in the affected VIN range actually end up failing? My understanding is that about 12 to 20% of “affected” M272 engines actually have their cog fail (the teeth wear smooth causing chain slip and cam timing codes) and require engine-out expensive repair.
Hi thanks for the feedback, by this time most of the M272 either probably have had the issue sorted by replacing the balance shaft or the car or engine is already in the scrap yard. I know this is a very common issue.
Great comparison between 112/3 & 272/3
Covered all points
I found e320 m112 rwd felt faster/more powerful then an e350 m272 4matic….?
Try resetting the Transmission, it will be very different.
Hi
What a lovely info about these engines
I would love to know the gearbox for 112 engine for w211 its part no
Thank you.
Perdonen que escriba en español suscriptores. Tiene toda la razón por donde sale aceite en los sitios descritos. Específicamente en la SUV . Tengo una LM 350 y tuve que arreglar el respiradero que mencionó a la parte de atrás de el motor. También por el filtro de aceite y la reserva de aceite de el power stiring . De lo demás es una SUV fuerte. Pero como todo auto. Pasada las 100 mil millas hay que cambiarle suspensión, cambio aceite d transmisión. Y de seguro al pasar estas millas se dañará también el condensador del aire acondicionado. Y también el selector de cambios de la transmisión padecen de ese mal. 🇵🇷
👍
M112 is probably one of the best, most reliable v6 engines ever produced. Ive never had any issues on them other than my own stupidity (i am a curb magnet lol)
Very true. Love M113 - M112.
Same goes for m113. Virtually same engine just 2 more cyl.
I have a question, maybe someone could help me. I have a M272 engine on an R class, and I would like to install the supercharger of the C32 AMG, that block is a M112, would it be possible? Tanks :)
I dont think so. These engines have completely different cylinder heads, the compressor will not fit.
👍
The whole point of the M272 is a high-capacity naturally aspirated engine with every sophistication (eg: twin-camshaft both banks, multiple valves/ cylinder), optimised fuel injection, aluminum block and NO nasty hot turbos or Kompressors. The joy of the M272 is in the large horsepower (about 275 bhp), capable of extended redline if ever needed, but making for a torquey, supremely UNDER-stressed engine and therefore a trouble-free long-life. They sadly no longer make such engines… now we are force-fed unpleasant tiny stressed-out turbos with an electric motor strapped on from MB, even in AMG guise!
Can you do 2006 Ml 350 engine vs ML 500 engine ?
What do you want to know, happy to help you.
Acceleration comparison is a bit unfair? Why not compare the 5.5 NA M113 to the 5.5 M273?
Yes you are right, but we are trying not to bring the AMG into the equation.
@@BenzAddictionbut you should as 5.4L M113 N/A is the closest to 5.5L M273. In fact M273 has about 20hp more and 7-speed gearbox so you need the AMG version for somewhat fair comparison
Frankly though amg m113 is barely different from the 5L or 4.3L.
Also the final SLK 55 used q version of the M273 engine with about 420hp :) M113 5.4 with long tube header and airbox can get close to that and more robust.
I have this engine in C55 estate. 70mph cruise it gets 32mpg 👍👍
@KingofInterns very good points, thanks mate.
the sl350 had a 3.5 m272 making 316hp so they make over 100hp than the m112
Thank you, correct, that's 2008, they raised the rpm to 7200 and compression ratio. I will need to update these later in another video.
Except for the m112k which made 350 horsepower. They didn't have a performance version of the m272 unfortunately :/
@@tati-anaroseee4316 True, but I think NA engines are more durable and still powerful.
@@tati-anaroseee4316 i agree they could of made a lot of power out of the m272-m273 line of engines they where great engines and still are today, i personally have a 3.5 m272 and its kinda slow but the 7 speed makes up for it
In my experience the m113 amg and regular is better . The m112 is too noisy because it’s under power .
