So I hope somebody can answer this before I rip the head of my mechanic. My egine has always sounded perfectly, no noises no ticks no nothing but was always purring like a cat. I go and get service done he claim he ordered special oil for my car w10-40 and there I got nervous apparently with good reason because I start the car and when put into gear and start rolling the engine gives a strange ticking noise. Not tick tick but more har metalic noise and im crying what the hell. So driving for a

It sounds like he didn't put something back right... but what?

Does he do the drain or suction method of engine oil removal? What you must try to do is locate where this noise is coming from. If he put the car on a hoist, maybe he knocked the exhaust pipe somehow and it is now touching the body. Or ask the shop for an explanation....:)

Back like promised ooh man....
Well to answer he use draining and he put on Luquid Moly 5-40
as I can see a rather good oil type 229.3
LIQUI MOLY - Motorenöle, Additive, Autopflege - Ölwegweiser

We reproduced the noise by putting car into D held food on brake and up to 1000RPM we could hear the cam chain I just wonder how the hell can that happen after a oil change makes no sense to me but he said seem like that thing now I forgot the name lol but that keeps the pressure on the cam-chain for keeping it tight has failed or the cam-chain itself so is what we can hear ...

Does this makes sense ? I am little I don't got the time nor the tools to do this myself! But I said to him are you sure he was like yes..
He tried to call a MB specialist to get it confirmed and with a price so nice one getting service now need replace cam chain damn...
Only just rounded 200.000 km is little to soon I think for that..

I like hear your opinion keyhole if yes is that I go for it?

If the timing chain is rattling it definitely could be the chain tensioner. This is a little bolt/spring assembly that screws into the timing case. Maybe the spring has suddenly broken & it is a coincidence about the oilchange.

To get access, WIS advises to remove a) fan shroud, b) alternator - so there will be a few hours of workshop labor here.

Your M112 engine is pretty bullet-proof - but you have a high mileage now with 200k km, so your tensioner could be toast. If the chain is allowed to run slack it will wear both the chain and the chain guides. If the timing chain breaks, you will blow up the engine - so that's the situation you are now faced with. You really have to go for it. Make sure that the shop knows the torque of the re-fitting the tensioner (80Nm)

Big big big thank you

Thanks keyhole for the advice I will diffidently go for it!
Is also what I have heard and know about the m112 engine so I will go for it.
I now await callback for a time for the repair!
I also think I just park the car until it is done because as you said it can blow up the engine.. My god yes a loose timing chain inside the engine I can only see what damage that can cause holy-moly....

:thumbsup::thumbsup::thumbsup::thumbsup:

To keyhole:bowdown::bowdown::bowdown:

thanks mate, is why I love this place.. Benzworld with keyhole in it makes it complete. And of course everybody else.

Damn was expecting repair today! I just cant figoure out I had my car at MB they told me yes is the Timing Chain I just wonder will that show up as an error code? I see more people saying timing chaing tensioner, MB didnt even mention it but I trust them just I dont know my car anymore god damn even the driving behavior of it has totally changed! Like that NOT Mb dealer replaced my engine lol... Loss of power, gear changes so weird I know have to floor the pedal totally all the way down before getting it down in gear else it feels like 2 gear all the time when accelrate I dont get it when in S it use to do it by itself!

Can the the timing chain has something to do with this? I mean if engine produce an error code perhaps to protect it from damange I dont know I just dont got the patients I want my car back lol..
The MB dealer asked me if we could take next week instead of today as they got some sicknesss and he told me because he want the right dude on my car...

Or perhaps I should just stop worry and wait to do that untill the chain has been replaced and then check if ok is ok if not take it from there..

I cannot understand why the chain needs replacing if it is only the tensioner that has (recently) failed. MB have provided a double-chain for reliability, and my local dealership tells me that they have never had one break on a M112 engine.

If the chain tensioner has failed, the chain will certainly rattle against the guides and the alloy cover. And the engine will run badly with the timing bad.

To replace the chain will double the work time - are they inflating this job?

Thanks for the quick reply Keyhole!

Me to I have heard the same thing from my old dealer in Denmark I made a call since I live in Sweden and the launguage difference sometimes creates confusion lol..
I will try contact MB again on Monday to check up on this I also think it sounds weird!!

Another thing the engine gets aprox 4 degrees warmer than it use to.
Before always 100% steady the needle has always been precisely on 80 Degrees tough I always taught normal operating temp is 90 Degrees?

Anyway since gonna pop open the engine I make them replace the thermostat, winter is on its doorsteep in Sweden here we get down to - 30 hehe and trust me the MB last winter ran like a dream, with winter spike tyres on it is fun,, but thinking about parking in garage this winte (maybe :)

Yes Keyhole I check up on this with them Monday then will answer what they say.
Thank you so much I truly appriciate it..

Wird thing is I can only reproduce the engine noise if I have it in Gear D or R then hold the brake and accelrate to 1000rpm then can hear it very clear, or if I drive of course, in N there is nothing...

My little baby:crybaby2::crybaby2::crybaby2:

Keyholde could you explain what
"are they inflating this job" means?
I am sorrry I never see that word like this lol..
My broken english forgive me, but I am surely pissed but I give MB the bennefit on doubt since I am not sure but is what I understand they told me timing chain not tensioner...

Spoke with MB dealer

So I got contact with MB they do my car tomorrow..

The ifnormation I got was yes the timing chain is double
but MB always recommend and I forgot to mention I just passed 200.000km
and found out was rather important sorry Keyhole my mistake..
But they say yes the chain is double but still no matter what we always recomment to change the timing chain and chain tensioner when passing 200.000 and the plan was tensioner but since you passed 200.000 and the problem I got is what it is we want change it as recommened because also like you mentioned yourself the M112 engine is strong but the timing chain if it brakes the engine is a goner...

So makes sence and is enough for me so please cross your fingers save a little prayer for me for a smooth repair tomorrow..

Sorry - I was using English slang there... It means 'building up' the job to make it seem bigger, at your expense, when not neccesary. It's always a risk if you are not familiar with the workshop.

In this case, as I have now realised, they are probably doing the right thing with this new chain, considering your mileage. (We do not have a word in English for 'distance in km on the clock') :)

See if you can get the old chain to examine the wear. Good luck with the workshop. It should run sweet after this!

timing chain replaced, timing chain tensioner replaced, thermostat replaced
all rocks picking my car tomorrow earling morning.
the old chain was 5 cm longer than the new one this says little about how much a timing chain can be streetched after 200.000km now I understand why and happy got it done! Thanks keyhole looking forward to pick it up and now also invested in the MB Carsoft 7.4 Interface Multiplexed installed on my old xp laptop works for my 38 pin conneter engine bay so no fuss now reading error codes. got the WIS program to same laptop so am happy... Thanks to Benzworld and people like Keyhole and others ty you all..

on the positive side,if it were a belt instead of a chain,it may have slipped or chewed-up a couple of tooth or even snapped the belt(especially since you kept running the engine) plus it wouldn't have rattled like a chain to warn you. in this case,valves touch pistons and you have a major($$) engine repair on your hands.

this is just one of the reasons i'm thinking of picking up a used CLK instead of a lexus SC300/400,even though lexus was trying to compete with the S-class with this model.

Of course bro thats what we are here for right ;-)
I got it made in Sweden AMG Mercedes Center Hedin Bilar 2,620.20 USD.
I added the faktura so you can see what you should expect.

By the way I do also know price in Denmark since im org from Denmark I checked Mercedes Copenhagen just in case, and they charge 1,804.55 USD

Anything else just ask man, oh by the way engine runs like a charm no noise what so ever happy I had it done...

The only reason the timing chain should wear so quickly (200 000kms is low mileage/distance) is if the oil changes were not done on a regular basis and the wrong oil was used.

These engines have been known to do 500 000kms without problems!

Chains don't stretch, they wear, causing it to elongate, but the links stay the same size, the pins wear. This is caused by heat and friction, generally caused by poor maintenance habits. This is not normal for 200K.. There may be some wear at that point, but well within the specs of the tensioner to take care of. I'm wondering if the chain, guides, and tensioner are getting the proper amount of oil, or what other parts may be warn causing excessive, premature failure.
