BMW M42 engine wierd noise

Can anyone tell me what the whining noise is?

Hey man . I have the same exact issue. Mine sound the same. Did you find out what it was ? Thanks

not yet.. but I am not going to give up! I have several parts and methods which I will test and hopefully I will find the reason for the whinning noise. How your noise appeared? Did you change some components of the timing chain assembly? Do you have any ideas?

In desperate but now I have my engine opened . I won’t give up and once I will find the problem I’ll come back to you
