I proudly own the mighty but much, much older V8-grandfather, the M 100 engine! 😉😄.....in a 6.9

[@DCMotorWerks]

I have one of those too :-)

[@00700556]

I have a m273 with 238,000 miles on it and still drives like new. Definitely have replaced the oil cooler gasket (both), water pump, recently power steering pump, radiator, engine mounts, those caps at the back. I mean I don’t mind it. It’s an older car so parts are cheap and the car is easy to work on.

[@angturil]

I own one on my CL500 2009 it has about 90k miles on it and I must say everything on this engine is easy, easy to maintain easy to replace easy to fix…. Super reliable so far I am considering to replace the chain tensioner soon as I get some noise at cold start coming from the chain but quite lightly…

[@jarydjackson8531]

M113K is my favorite engine. Not sorry about it.

[@zach359]

M119 was badass. Great reliable engine. My S500. Is old reliable now, never have a issue or worry

[@DCMotorWerks]

Love the M119. I still consider that more of a vintage V8. Planning a video on that engine....

[@JohnStonerxD]

Great video again guys, loved to watch it and also great that you made an in depth technical video about a specific engine again - love this kind of content You guys somehow manage to always have a great vibe in your videos and I also really like that fact that your technicians are involved in the videos as well, keep on going and you'll become a very successful channel - I'm totally sure about that Drink a beer on me 🍺, best greetings from Germany

[@lanefeatherston3699]

If your m273 eng number is greater than 088611 you're good

[@DCMotorWerks]

Correct

[@kristingeorgiev3295]

where to look that up in the engine code? Thanks!

[@RexNathanChan]

If you have the VIN, use decoder to find engine serial. Or look on the engine itself ​@@kristingeorgiev3295

[@RexNathanChan]

​@@kristingeorgiev3295it's literally the last 6 digits of the engine serial number

[@TheBanOneA]

Thanks guys, great summary of potential issues on the M273. Only comment I´d add to the question of repairing the linkage on the intake manifold vs replacing the entire manifold: I´ve heard of cases where the plastic flaps inside the manifold got brittle with age and ended up inside the engine. That´s why I chose to replace the intake manifold after 15 years on my 2009 E550. All there is to say about the M273 really, awesome powerful engines with a sweet V8 tune and not too bad when it comes to fuel economy either.

[@DCMotorWerks]

We prefer to replace

[@basilharmony3389]

Im stuck with the m278 engine😂, yes 140k miles as well, just wish me luck please 🙏, so far running great as far as I’m concerned.

[@bicylindrico]

Intake manifolds, oil coolers, camshaft adjusters, main bearings, etc. They were good for 100k and then fell apart

[@djwarren5081]

I really enjoy these technical projects. Thanks for the great explanation.

[@romans7177]

We had an s550 with head gasket problems that we fixed with engine sealer. I know it’s ghetto but it worked fine at 258k miles the driveshaft going to the front wheels wobbled and smacked a hole in the side of the transmission. Idk if it’s better than the 113.

Mine i think is doing the same thing i have 130k miles scanner says left/right camshaft incorrect position

[@keithgreenaway2690]

So you start by opening up a M273 with only 38,000 miles on it with a worn out timing gear???? You just answered your own question. I have 2 E430’s with the M113 with over 250,000 miles, never a problem. The best V8 they ever made.

[@DCMotorWerks]

Eh. Do a bunch of 113 valve covers, rear mains, etc like we have and the small run of 273’s with the idler gear issue aren’t anything to fuss about. I’ll take the 273 anyday

[@4JaayTv]

So how do you guys think this engine will respond to boost ?

[@killertay1947]

Can I contact you to do mine in the future?

[@theo3000]

No. It is not.

[@peanutpckrupper3323]

As the owner/builder of an M273 swapped GLK I say yes it's way better than the M113

281k miles on our 2009 GL450. Oil changed every 5k miles. Sent an oil sample from the last oil change to the lab to check the health of the engine. Elevated levels of iron, possibly from the cams. Just gonna keep running it as long as it’ll go! I just want to hit 300k, then it doesn’t owe me any more than that.

[@DCMotorWerks]

We have one that comes for service with about 305k on it.

Did they say how elevated the levels were?

[@davidkrumwiede446]

@@alextorkelsonIron in the oil is elevated, average is 17 after 6600 miles, mine measures 26 after 5000 miles. They say it may be from steel-on-steel wear like cam/lifters.

What's the most reliable v6 and v8 Mercedes engine(s)? I love the Mercedes styling and performance. Lexus have the reliability but the performance is dull.

[@mpkp2011]

Best V6 is the M272 after the 09 era. No turbos and really solid engines

[@byronhagan82]

i have 2010 e500, the M273 has never pit a foot wrong.

[@wolfgangkaminski4580]

WHAT A SHIT ENGINE when you have to repair it after 38k miles!! 38000 miles IS NOTHING!! This is a VERY VERY BAD ENGINE!!!!

[@Wargasm54]

He explained why. I’ve had 3 cars with the M273 and currently have 1 (E550). Have never had a hint of a problem with the ones I’ve owned. There was a batch (pre 2006) that had bad teeth on the timing gear. They were pro rated under warranty. But the 273 in general is a solid V8 and they make great power (400hp) from a naturally aspirated engine. I’ve never had one go wonky on me. And always maintain a perfect idle.

[@mpkp2011]

In your opinion, is this engine more reliable than the M278? Looking at picking one of these up in a W212 E class and am debating on which era V8 to grab

[@DCMotorWerks]

Stay away from the 278. Watch our video about it

[@mpkp2011]

@DCMotorWerks I appreciate the response! Funny enough I just watched that and sent it to my dad who has an S class with that motor. Truly great content guys thank you! Any word on the M276 engine? The face-lift E350 is very appealing at this point

[@2002000097]

Don't M272 and M273 suffer from bore scoring and tapping noise on idle when hot?

[@DCMotorWerks]

The 278 does

[@qualityinn2516]

are the replacement parts better then the old stuff that breaks? i wish you were in Texas!

[@DCMotorWerks]

Generally yes. It is case by case though.

[@expofcam]

good video didn’t know much about these engines, shop looks like a cool environment to work in 👏

We have a great time! Thank you.

[@BurntOrangeHorn78]

Later BMW V8 are much better. The N63 of this era 14:00 had problems, too.

[@DCMotorWerks]

BMW has yet to make a V8 engine that is worth its weight. scored cylinders, timing chain problems, valve stem seals, oil leaks galore. They're awful.

[@BurntOrangeHorn78]

@@DCMotorWerks Kind of showing your lack of knowledge there. But since you do not work on then, how could you know?

[@JohnStonerxD]

I'd say the last good bmw v8 was in the e38/39 chassis with the M62/S62 engine... all the later ones are not reliable in my opinion, talk about connecting rods and other problems in the S65 M3 or the even newer ones you talked about with the N63 that have all sorts of problems I have to admit though BMW always delivers on their bread and butter motors, the inline sixes (not the diesel ones anymore unfortunately) I think overall every manufacturer has their own great designs and innovations but also horrible engineering choices on the other hand so it's basically hard to say that one brand overall is good or bad
