First of all, welcome, and congratulations on your purchase!
That sounds like the variator needs replacing - if the clattering sound is audible during and just after startup.
Are you new to Alfa twin spark ownership?
Hey there & thank you

Yes i'm new to Alfa Romeo this is my first Alfa car and i absolutely have no idea about its mechanical stuff. So you guys think it's the variator ? How much would be the cost of a new part in order to replace this? If we connect the cars ECU to a PC with diagnostics will it show anything up? My friend who is a very good mechanic said that it's the head gasket and it needs replacement..with that i'll do a general service too.

As Jeremy says, Credible...
It's the camshaft variator.
Do you, er, have any other friends, who are mechanics...?
Yes i do, but i trust my close friend more and he is experienced..although he did a short "diagnosis" just by listening the engine running and he told me it's 99% the head gasket.
Also, my car has done in total about 190.000km
PS: I can upload a video with the engine running if you guys like.
Thanks in advance guys !
