So you think your timing chain rattles?

Vehicle : W202, Engine : 605 5cyl diesel 190,000 mls
only owned this car for 2 months. when starting from cold it sounded very rattly like timing chain worn. As it warmed up, it quietened down. After 2minutes it was OK. I finally tracked down the noise to the aux belt tensioner damper, the small hydraulic strut about 6ins long. Strange that it went quiet after 2mins & it did really sound like chain. In fact the hydraulic part was OK, it was the metal eye bonded into rubber that had worn and was loose in the rubber. I suppose I could have made a new bush for it but the complete part only cost 15 from Eurocarparts, in Glasgow. The Moral of this story, dont jump to conclusions about timing chain problems
