M156 rattle noise beyond 2500 rpm
Hi
I've bought a 2008 CL63 about 3 month ago, the car been sitting since 2014 I've done all the basic maintance
my problem now is the car has a strange noise coming from the engine bay start at around 2500 rpm, no idle rattle and no cold start rattle also no check engine light.
I opened the valve cover to check the cams and lifter, all 4 cams has been changed with the new part number thankfully no wear on them at all
took the car to 3 different indy mercedes shop all sayed it is normal but I think not. the noise is there when the car is standing at 2500 rpm but it is more clear while driving. the car other than this noise drives perfectly.
will post a link so you can hear the noise
any help would be appreciated.
Here is a video while driving
and here is another while idle

i don't hear anything other than a VERY VERY healthy engine. maybe the audio quality of the video isn't very good?

i hear a perfect engine. there is also some injector clicking noise also in the video. maybe camshaft adjuster, but its not close to being bad yet. pretty sure its the camshaft adjuster.
