Timing Drive Components: Installation

All engines 

NOTE: The engine comes equipped with either a roller primary timing chain or an inverted tooth primary timing chain. The roller timing chain engine comes equipped with either a composite RH timing chain guide requiring the timing chain to ride on the outer side of the guide or a stamped steel RH timing chain guide requiring the timing chain to ride on the inner side of the guide. All roller timing chain engine replacement RH timing chain guides will be the stamped steel design.
