Inspection and Adjustment

INFOID:0000000010715452

INSPECTION

Perform inspection as follows after removal, installation or replacement of camshaft or valve-related parts, or if
there is unusual engine conditions regarding valve clearance. 
1.

Remove rocker cover. Refer to 

EM-170, "Exploded View"

.

2.

Measure the valve clearance with the following procedure:

a.

Set No. 1 cylinder at TDC of its compression stroke.
• Rotate crankshaft pulley 

 clockwise and align TDC mark (no

paint) 

 to timing indicator 

 on front cover.

• At the same time, check that both intake and exhaust cam

noses of No. 1 cylinder face inside (

) as shown in the figure.

• If they do not face inside, rotate crankshaft pulley once more

(360 degrees) and align as shown in the figure.

b.

Using a feeler gauge, measure the clearance between valve
lifter and camshaft.

CAMSHAFT VALVE CLEARANCE

• By referring to the figure, measure the valve clearances at

locations marked “

×

” as shown in the table below [locations

indicated with black arrow (

) in the figure] with a feeler

gauge.

c.

Set No. 4 cylinder at TDC of its compression stroke.
• Rotate crankshaft pulley 

 one revolution (360 degrees) and

align TDC mark (no paint) 

 to timing indicator 

 on front

cover. 

• By referring to the figure, measure the valve clearance at loca-

tions marked “

×

” as shown in the table below [locations indi-

cated with black arrow (

) in the figure] with a feeler gauge. 

3.

If out of standard, perform adjustment. Refer to “ADJUSTMENT”.

ADJUSTMENT

• Perform adjustment depending on selected head thickness of valve lifter.

1.

Remove camshaft. Refer to 

EM-196, "Exploded View"

.

2.

Remove valve lifters at the locations that are out of the standard.
