NOTICE: During engine repair procedures, cleanliness is extremely important. All parts must be thoroughly cleaned and any foreign material, including any material created while cleaning gasket surfaces, that enters the oil passages, coolant passages or the oil pan, can cause engine failure.
NOTE: Assembly of the engine requires various inspections/measurements of the engine components (engine block, crankshaft, connecting rods, pistons and piston rings). These inspections/measurements will aid in determining if the engine components will require replacement. For additional information, refer to Engine System - General Information Procedures.
NOTE: The 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 replacement RH timing chain guides will be the stamped steel design.

Using a feeler gauge, confirm that the valve tappet clearances are within specification. If valve tappet clearances are not within specification, the clearance must be adjusted by installing new valve tappet(s) of the correct size. For additional information, refer to Valve Clearance Check Adjustments.
