It's a job for a pro really. It's bolted to the end of the inlet cam. It's quite expensive iirc£ £400 for the part.

Do you have the M111 or M271 engine?

 

[nickid]

I have the m111 engine

oh fantastic. that's what I didn't want to hear

The M111 engine has an adjustable inlet camshaft. If its the older design as fitted to the M104 engine then there's a little internal spring that sometimes breaks. If its that-- it can be replaced provided there is no more internal damage to seals etc. However its not a job to be taken lightly as Olly says-- as it means disturbing the engine timing gear. Here's a pdf which you might find useful? http://www.startekinfo.com/StarTek/outside/12264/Program/Engine/104/05-2160.pdf

How do I know what engine m104 or m111

 

[BlackC55]

Its a 111. A 104 is a 6cyl

 

[nickid]

thought it would be.
now do I need to buy the whole camshaft adjuster? and do I need to buy anything else to stop the brrrr sound ?

 

[BlackC55]

Yes the whole adjuster. You will also need a rocker cover gasket. It is not that easy to do.

The tensioner has to be removed and re-set and the timing has to be spot on.

so I am looking at a bill I cant really afford

 

[nickid]

I get no noise on start up of rattling chain or any other noise only the brrrr for split second as I rev and let it fall again. could it be a worn cog or magnet instead ?

 

[BlackC55]

It WILL be the adjuster. I am pretty sure of it.

I expect £800 would cover the repair so not the end of the world for a Mercedes. It can rattle for along time before it needs to be replaced.

 

[nickid]

mine dosent rattle but the noise as described

is that from Mercedes?

 

[grober]

Sorry you misunderstood--- the camshaft adjuster found on the M111 engine is likely to be exactly the same as the one found on the M104.[ both same generation/design of engines one 4 cylinders one 6 cylinders as has been said] So the pdf link I posted will likely apply to your engine also. I only posted the M104 reference because its available online and there's not one for the M111.

 

[BlackC55]

is that from Mercedes?

The part? Yes you will have to get it from a mb
dealer.

 

[nickid]

that's great mate. I just need to find the part I need and then try and replace it myself. cant afford the cost of having it done.

saw a second hand one on ebay in america

Follow the instructions. Re-loading the chain tensioner and the timing up is the part you must get right. If not you will be looking for a new engine!!!
