Hi all,
My SC220CDI engine is making a strange noise, it sounds like a chain or something metallic, that gradually increase as rpm rise!
Doing this noise for 40000km, and being noticeably loud with time. The noise is nothing exaggerated but its not normal, and I have afraid of damaging something, but the problem is finding the problem with major expenses!
-The noise is not present when the engine is cold, after warming up it starts to make the noise.
-The noise is very hard to look from where its from, but looks like at the passenger side, front top of the engine.
-With the belt off the noise is still there.
-I tried new vacuum pump, high pressure pump, and not tried yet the diesel pump, all the parts where the noise looks to came from!
Went to MB dealer, and they changed my chain tensioner, but the noise is still there!
Than the tech said that they have to open the valves cover to look inside, the noise looks like the chain inside the engine and they have to look, or... it could be the chain of the oil pump, and for that have to remove the engine off!!!!!!!!!!
It had to be hydraulic relationed, since when cold there is no noise!
Any opinions what to do, or suggestions?
I don't know what to do!
