there’s really no way to make the service department replace anything Ford’s warranty folks don’t approve. If they prescribe a new engine, that’s all you’ll get. Ford won’t give service departments a blank check to go inspect other components.As part of the replacement, I would ask them to inspect the oxygen sensors and the face of the catalytic converter. It there is damage to either this will cause more problems down the road. We should put together a list of things that shall be replaced and things that should be looked at. Imagine a chunk of valve or massive oil deposits on your converter.
