Valve Clearance Adjustment
NOTE:
Valves should be adjusted only when the cylinder head temperature is less than 100°F (38°C) .
After adjusting, retorque the crankshaft pulley bolt to 245 N.m (25.0 kgf.m, 181 lbf.ft) .
Remove the cylinder head cover.
Set No.1 piston at TDC . "UP" mark on the camshaft pulley should be at top, and TDC grooves on the camshaft pulley should align with cylinder head surface.
Adjust valves on No.1 cylinder.
Intake:
0.26 mm ±0.02 mm (0.010 in) ±(0.0008 in)
Exhaust:
0.30 mm ±0.02 mm (0.012 in) ±(0.0008 in)
Loosen the locknut, and turn the adjusting screw until the feeler gauge slides back and forth with a slight amount of drag.
Tighten the locknut and check clearance again. Repeat adjustment if necessary.
Rotate crankshaft 180° counterclockwise (Camshaft pulley turns 90°) . The "UP" mark should be on the exhaust side. Adjust valves on No.3 cylinder.
Rotate crankshaft 180° counterclockwise to bring No.4 piston to TDC . Both TDC grooves are once again visible. Adjust valves on No.4 cylinder.
Rotate crankshaft 180° counterclockwise to bring No.2 piston to TDC . The "UP" mark should be on the intake side. Adjust valves on No.2 cylinder.
