INSPECTION

1. INSPECT VALVE CLEARANCE

HINT: Inspect and adjust the valve clearance when the engine is cold.





(a) Check only the valves indicated in the illustration.
(1) Using a feeler gauge, measure the clearance between each valve lifter and camshaft.
(2) Record any valve clearance measurements that are out of the specified range. These measurements will be used later to determine the size of the adjustment shim to be installed.
Valve clearance (Cold):





(b) Turn the crankshaft clockwise 1 revolution (360°) and set the No. 4 cylinder to TDC/compression.





(c) Check only the valves indicated in the illustration.
(1) Using a feeler gauge, measure the clearance between each valve lifter and camshaft.
(2) Record any valve clearance measurements that are out of the specified range. These measurements will be used later to determine the size of the adjustment shim to be installed.
