My 2016 metris has a the same issue ( code for exhaust camshaft code rattles, turns over multiple times before start but when I clear the code it starts perfectly fine) thank you I think you just diagnose my issue 😊😊

Nice I really love it

Thank you sir!

Could you please tell the tightening torque for the camshaft retainers?

[@miguelmartinez9523]

What is the part number in the intake camshaft?

[@allancustodio-yg1or]

intake camshaft need to be replace because of pules wheel drive is out of position so that why the fault code is camshaft intake.

[@matevid1986]

Nice video, thanks for sharing. I have an A class MB 180i, I am about replacing timing chain tensioner. How can I confirm my motor is M274 as the one you showed us? Could you recommend a repair workshop manual you are using? Thanks again for sharing your experience / knowledge.

[@luxurautomotive8913]

We use Mercedes Benz software and have Mercedes Benz subscription which give us access to repair manuals .

[@eagoleye]

Thank you!

Hi there, just watched your video. I’m rebuilding an M2 74 engine at home, there’s four bolts and brackets on top of the engine that hold down the camshaft would you be able to tell me what those torque settings are? I can’t find them anywhere.

[@algis3207]

Hello! Thanks for sharing your work and experience! Other craftsmen recommend welding these discs so that there is no more lag, what do you think?

[@luxurautomotive8913]

I HAVE ALSO DONE THE SAME THING. TAG WELD JUST SO IT DOESN'T MOVE. ONE TIME, I INSTALLED A BRAND NEW CAM & THE PALTE TURNED AFTER THE FIRST START. I HAD TO REOPEN EVERYTHING TO READJUST THE PLATE MANUALLY AND TAG WELD IT. LIKE A DOT, YOU DON'T HAVE TO WELD THE COMPLETE PLATE.

[@algis3207]

@@luxurautomotive8913 I really don't understand why it is not already done at the factory!

Info on the cam tool?

Hi, is this information relative for the M274 fitted in a 2013 a250? Appreciate your reply.

[@luxurautomotive8913]

Yes sir

[@VictorBas-zi4mu]

Can I work with you? I need a job and I’m an engineer specifically on Mercedes Benz

[@user-go8lr5lp9c]

Can a camadjuster throw missfire codes after replacing the camshaft intake valve on the same engine m274

[@eagoleye]

Yes. Because if the cams off timing, the valves won’t close on time so you get single or random multiple misfire faults.

[@marcis8819]

Hello. Unfortunately my English isn't that good. Would you say that the m274 is better than the m271? Or do both engines have the same problems with the timing chain?
Greetings

[@luxurautomotive8913]

There are 2 different engine. But M271 have commend issue with their runner. They are both good engine but you might find either one that would have timing issue . 🙏

[@AldoDellaValle]

would be the Valves Bent at this point? how would you check for that?

[@luxurautomotive8913]

No the valves will be ok unless the timing chain is broken completely or the tensioner got stock and chain has jump more than a few tooth.

[@Wakanda4eva6996]

With the cams 'pinned' at TDC/O|T, can you rotate the crankshaft through the full rotations necessary to feed a new timing chain through without hitting the valves?

[@luxurautomotive8913]

You have to make sure all the valves are closed. remove the camshaft completely so that way all the valves are closed and you have more room to drew the chain in and you have no issue turning the engine. Once you lock your chain is when you install the camshaft and make sure you sparked marks line up, flat with the cylinder head surf.

[@Wakanda4eva6996]

I understand. I've seen some people draw in the chain on he M270 and M271 engines and they left the camshafts in, that's why i was asking. Thanks for the info!@@luxurautomotive8913

[@Wakanda4eva6996]

Awesome. Thanks for the info man!. Would you also know when tightening the camshaft adjusters to the camshafts, do you have to put the crank at 10 Degrees or so before TDC so you dont lose timing? I've seen a couple of videos on RUclips where they put the crank at lets say 5-10 Degrees before TDC so when they tighten down the adjuster valves they don't lose timing? I don't know why they would need to do that if they have the timing tool locked in place. @@luxurautomotive8913

[@Dungshoveleux]

So how many miles on the engine and did it have a full service history?

[@luxurautomotive8913]

67k. It has e been service regularly for the oil changes.

[@bmwlane8834]

Wow that's low! I'm at 133,000 miles on my metris, same engine....it's been perfect....not one problem. But lots of highway miles.

[@Dungshoveleux]

​My M274 is on 210,000 miles and no such timing problems yet. A 2016 s205 c200se @@luxurautomotive8913

[@ikeudechukwu5018]

Honestly, the M270/274 should be trashed. The M139 engine in the CLA 45 abd its predecessor the M133 which are also both 4 cylinders did not give this much problems.

[@s4127419]

after all these years, from w203, w204 to w205, they still can’t make it right ?! Why ? I mean, I never change a Toyota or Honda camshaft even exceeding 300K miles , but damn , m271 m274 ,m276 m278, they all the same , around 100k miles , boom 💥 .

[@luxurautomotive8913]

If toyota and Honda wanted to design the same engine I promise you they would run in to a same exact issue. Toyota and Honda do not have the same engine design at all my friend. Remember it’s very hard and is not easy to design an engine. It takes years of R&D and updates. It’s easy to make a 4-6 cylinder noun turbo reliable engine. But not 4 and 6 cylinder turbo with hi horse power. 🙏
