Valve Clearance

Warm engine to normal operating temperature. Remove valve cover and spark plugs. Rotate crankshaft to bring piston No. 1 to TDC on compression stroke (lifters on cylinder No. 1 should be loose).
Measure valve clearance on intake valves for cylinders No. 1 and 2 and valve clearance on exhaust valves for cylinders No. 1 and 3. See the VALVE CLEARANCE ADJUSTMENT table.
Rotate crankshaft 360 degrees to bring piston No. 4 to TDC on compression stroke. Using a feeler gauge, measure valve clearance on intake valves for cylinders No. 3 and 4 and valve clearance on exhaust valves for cylinders No. 2 and 4. See the VALVE CLEARANCE ADJUSTMENT table. Adjust valve clearances by replacing lifter shims.
