So, when I started the car this morning I notice this sort of "knocking" noise, which seems louder in the passenger side of the engine bay.

After the car warms up it disappears, I spoke with a friend that is more mechanically inclined than I and he said it seems to be the clutch bearing.

The noise disappears when you rev the engine (or the engine noise overcome this noise) which (I guess) show is not related to the pistons or valves.

Can anyone recognize what is it ?

I think I found my issue:

Even though my noise is not that loud, it seems to be it.

Does anyone knows how soon it has to be fixed ? Any recommendation of a nice shop to do it ?

Thanks Rev !

Holy crap, it seems to be way more common than I thought

I'm reading the 99 pages, I just can seem to find out if there is a long term damage if that doesn't get fixed... I've seem people saying that they drove for a long time with no problems (other than the bothering noise)...

Should I get that fixed ?
