WARNING: This page is about a different car, the 2011 Lincoln MKZ and 2011 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: If the engine is repaired or replaced because of upper engine failure, typically including valve or piston damage, check the intake manifold for metal debris. If metal debris is found, install a new intake manifold. Failure to follow these instructions can result in engine damage.
