Timing chain noises

This would be a major task for any mechanic. Are you sure its the timing chain and not a defective water pump / alternator / aircon pump rattling? Generally Benz timing chains would do 200k if properly maintained which is why I question your request?
Have you done this mileage and have you had a good look at the serpentine aux drive belt?

RE: 1991 Mercedes Benz 500SL... when I put gas in the tank it doesnt leak until I start the car & then it leaks profusely underneath the rear passenger side.

Hi there. The reason it only leaks when you turn the car on is because the gas tank is pressurized, but only after the car has had a chance to pressurize the tank (when the car is turned on). To fix this, you need a new gas tank! Alex

2002 mercedes e 320 ,with 114,000 miles ,should timing chain/belt be replaced

That V-6 has a timing chain.There should be no reason to replace it at that mileage,assuming normal maintenance and no extenuating circumstances.These don't have problems like the old V-8s that would break the upper timing chain guides.I like these engines.We do replace a lot of the ignition coils and chase around electrical problems on a regular basis.

When to change cam belt on 2006 c180 with 95000kM

Mercedes engines use timing chains not belts. The timing chain should last the life of the engine and no service is needed, unless something out of the ordinary happens, worn guide or sprocket.

Merces benz c230 timing chain replacement procedure

so it takes some Pin pullers, or a litlte bit of messing around witth proper sized (heavy duty) bolt to pull the pins, i cannot seem to find the timing marks on mine once i got it offand want to put back on, i have a chilton and it doesnt help. if you buy the 100 -200 dolar shop manual from bentley it would probably be quite simple :)

pull, pins, timing cover, water pump, solenoid, etc. to get to timing cover, uppe and lower,pull valve cover, and loosen cam (exhaust side) to get chain off. :)
