INSPECT VALVE CLEARANCE (a) Check only those valves indicated in the illustration. • Using a feeler gauge, measure the clearance be- tween the valve lifter and camshaft. • Record the valve clearance measurements of those that are out of specification. They will be used later to determine the required replacement adjusting shim. Valve clearance (Cold): Intake 0.15 - 0.25 mm (0.006 - 0.010 in.) Exhaust 0.25 - 0.35 mm (0.010 - 0.014 in.) (b) Turn the crankshaft pulley 1 revolution (360°), and align the groove with timing mark "0" of the No.1 timing belt cov- er. (c) Check only the valves indicated as shown. Measure the valve clearance. (See procedure in step (a)) P10711 2 2 4 4 6 6 EX IN 3 3 5 5 6 6 1997 SUPRA (RM502U) Author : Date : 1110
