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 EM-49, "Exploded View".
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 EM-149, "Camshaft".
NOTE: Be sure to note the following points when measuring valve clearance on the intake side.
• Before measuring, check that the position of drive shaft nose is within the angle shown in the figure.
A : Bank 1
B : Feeler gauge (commercial service tool)
D : View D
c : 45 degrees (drive shaft nose angle)
: Insertion direction of feeler gauge on the bank 1
: Insertion direction of feeler gauge on the bank 2
• 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.
• Check that exhaust cam nose on No. 1 cylinder (engine front side of bank 1) is located as shown in the figure.
• 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 “×” as shown in the table below (locations indicated in the figure).
• No. 1 cylinder at compression TDC
