1979 AQ120B w/Corroded Exhaust Port
Brand new to the Forum so hope you guys can help. Replaced exhaust manifold and found a badly corroded #4 exhaust port on the head. Heard of a "steel" insert used. (Insert might be from factory to prevent problem.) Anyone heard of this or any other fix? Any info will be appreciated.
Thanks
