Just wondering if anyone would be able to help in the restoration of my 1971 1750. I've noticed in a few pictures of engines that there seems to be a hose attachment from an outlet port on the cam cover going directly into the air filter housing attached to the webers. With the limited amount of literature that I've been able to aquire, I can't seem to find any mention of said hose. I've attached a picture of my engine bay. Any help would be greatly appreciated.
Yes, those two attachments are supposed to be connected by a L-shaped rubber hose with a clamp at each end. The picture here is of a GT1300Junior (1971) but you can see the breather hose going from the camshaft cover to the air cleaner housing.
Hmmm, I don't know if anybody have the original Alfa piece. You may be able to find a rubber hose with 90 degree bend at some local parts store, or if you can source a section of a hard rubber hose (closer to plastic I would say), you can probably heat it up and bend it into the desired shape (stuffing the hose with sand would help it from collapsing when being bent). Alternatively, if you don't care about originality you can source a 90 degree metal elbow piece at a plumming store or a hardware store and connect two short sections of rubber hoses with it (this probably is the easiest way to tackle this).
