"Removed catalytic converter heat shield and found crack running down the exhaust manifold causing more air to be processed by oxygen sensors, making car run leaner and hotter, recommend replacing catalytic converter and exhaust manifold assembly for car to pass."
My question: Can I have crack on the exhaust manifold welded? Will that allow me to pass the smog check?
The mechanic said that the catalytic converter was fine
have the same problem?
