Breather Pipes

Hi folks, i am trying to source some breather pipes but im.not having any luck.

They are behind the inlet manifold attached to a little metal block and are perished.

Can anyone advise where i could get these and also what that 'metal block piece' is????

Thanks.

Crazy Quiffs will sort you out with these mate ….. 

What are they called? And what is that thing they are plumbed into behind the inlet manifold?

Auxiliary air valve or AAV. It adjusts the air mixture on warm up.
