Valve Clearance: Adjustments

VALVE CLEARANCE ADJUSTMENT


Note: Valves should be adjusted cold when the cylinder head temperature is less than 100° (38°C). After adjusting, retorque the crankshaft pulley bolt to 250 N.m 125.0 kg-m, 181 lb-ft)





1. Remove the cylinder head cover.






2. Set No. 1 piston at TDC. "UP" marks on the camshaft pulleys should be at top, and TDC grooves on the camshaft pulleys should align with cylinder head surface.
3. Adjust valves on No.1 cylinder.


Valve Clearance:
Intake: 0.07-0.11 mm (0.003-0.004 in)
Exhaust: 0.15-0.19 mm (0.006-0.007 in)





4. Loosen locknut and turn adjusting screw until feeler gauge slides back and forth with slight amount of drag.





5. Tighten the locknut and check clearance again. Repeat adjustment if necessary.






6. Rotate crankshaft 180° counterclockwise (camshaft pulleys turns 90°). The "UP" marks should be at exhaust side. Adjust valves on No.3 cylinder.





7. Rotate crankshaft 180° counterclockwise to bring No.4 piston to TDC. the TDC grooves are once again aligned. Adjust valves on No.4 cylinder.





8. Rotate crankshaft 180° counterclockwise to bring No.2 piston to TDC. The "UP" marks should be at intake side. Adjust valves on No.2 cylinder.
