is in my opinion a fresh air intake see bonnet.
I once had spare parts from this vehicle owner bought gearbox, steering column suspensions and many small parts, as well as counters. All with Tipo 256 specifications. If you can say that! According to transmission translation. Unfortunately sold for a long time to Russia.
