Timing Chain or Timing Belt?

[innaadrian2007]

Hey all, this is my first post! Love the site...

Does anyone know if my 1999 E430 Sport has a timing belt or timing chain?

Thanks in advance!

If the car has a star somewhere, it should be a Mercedes and it would have a chain instead of a belt (I'm not sure actually if a timing belt had been used on some engines but I'm not aware of any, this one would have a chain anyway).

The chain too needs to be serviced although it would accept a lot more miles.

By the way, this one must be a W210 car.

Thanks for the info. So what kind of maintenance should I be doing on the chain?

unless you are having problems, the chain doesnt need to be replaced. only time i have seen a need for the chain to be replaced is the chain having slack causing rough idle issues and or noises.

Only if you have been using unapproved oils and indicate excessive mis-alignment of the cam to crank timing...

Timing chains should be inspected at regular intervals. The newer engines off the top of my head are checked at or around 140,000 miles (W211).

I realised I was using a misleading word. Inspection would have been right like the experts above stated. Then of course if at some point the inspection shows that service is needed, the chain and relevant parts are replaced with new.

Streetglover is experienced enough to inspect the car by listening to the engine sound.

Normally if the car is maintained as suggested by MB the chains last until engine overhaul, at which time they should be replaced.

Not so sure, like those single row chain W140 engines, but I don't see the connection to the sentence you quoted. One would still need to inspect the chain to be sure the car has been properly maintained and no service for the chain is needed?
