VALVE CLEARANCE INSPECTION [WITH DIESEL PARTICULATE FILTER]

1. Remove the cylinder head cover.

2. Turn the crankshaft and align the timing marks so that the piston of the No.1 or No.4 cylinder is at TDC of compression.

3. Measure the valve clearances A with the No.1 cylinder at TDC of compression, and those of B with the No.4 cylinder at TDC of compression.

IN: 0.09-0.21 mm {0.004-0.008 in}

EX: 0.29-0.41 mm {0.012-0.016 in}

4. If the valve clearance is not within the specification, adjust the valve clearance. (See VALVE CLEARANCE ADJUSTMENT [WITH DIESEL PARTICULATE FILTER])

5. Turn the crankshaft one full turn and measure the remaining valve clearances. Adjust the valve clearance if necessary.
