Description And Operation: Engine: Notes
WARNING: This page is about a different car, the 2010 Lincoln MKZ and 2010 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Early build engines have 11 fastener valve covers, late built engines have 9 fastener valve covers. Do not attempt to install bolts in the 2 empty late build valve cover holes or damage to the valve cover will occur.
NOTE:
On early build engines, the timing chain rides on the inner side of the RH timing chain guide. Late build engines are equipped with a different design RH timing chain guide that requires the timing chain to ride on the outer side of the RH timing chain guide. For service, all replacement RH timing chain guides will be the late build design.
