BASIC INSPECTION

CAMSHAFT VALVE CLEARANCE

Inspection and Adjustment

INSPECTION

Check valve clearance if applicable to the following cases:

Intake side:

At the removal and installation of VVEL ladder assembly or valve-related parts, or at the occurrence of malfunction (poor starting, idle malfunction, unusual noise) due to aged deterioration in valve clearance.

CAUTION: Valve clearance check on the intake side is not required after replacing the VVEL ladder assembly and cylinder head assembly with a new one. (Install new VVEL ladder assembly and cylinder head assembly in factory-shipped condition because it is factory-adjusted and inspected.)

NOTE: VVEL ladder assembly cannot be replaced as a single part, because it is machined together with cylinder head assembly.

Exhaust side:

At the removal, installation, and replacement of camshaft (EXH) or valve-related parts, or at the occurrence of malfunction (poor starting, idle malfunction, unusual noise) due to aged deterioration in valve clearance.

1. Remove rocker covers (bank 1 and bank 2). Refer to "REMOVAL AND INSTALLATION".

2. Measure the valve clearance as follows:

Use the feeler gauge (commercial service tool) of curved-tip. This allows the feeler gauge to access the clearance between camshaft and valve lifter with ease.

Valve clearance: Refer to "CAMSHAFT".

Before measuring, check that the position of drive shaft nose is within the angle shown in the figure.

Fig. 7: Measuring Valve Clearance

Refer to the illustration for the insertion direction of the feeler gauge since the direction depends on the bank.

a. Set No. 1 cylinder at TDC of its compression stroke.

Rotate crankshaft pulley clockwise to align timing mark (grooved line without color) with timing indicator.

Fig. 8: Locating Timing Mark (Grooved Line Without Color)

Check that exhaust cam nose on No. 1 cylinder (engine front side of bank 1) is located as shown in the figure.

Fig. 9: Identifying Exhaust Cam Nose On No. 1 Cylinder (Engine Front Side Of Bank 1)

If not, turn crankshaft one revolution (360 degrees) and align as shown in the figure.

By referring to the figure, measure the valve clearances at locations marked "x" as shown in the table below (locations indicated in the figure).
