Mechanical maintenance manual for the 16V 1.4L/1.6L engine (in English). You can download this completely free service manual. This engine is used for example in the Daewoo Lanos.
Thanks friends for this material, see if it serves me. I actually look for the Isuzu 1.3 Dohc Diesel 16 valves, which is installed in the Chevrolet Combo Truck Year 2006.
