1. Set the No.1 and No.5 journals on V-blocks.

2. Measure the camshaft runout.

• If not as specified, replace the camshaft.

Maximum runout:

0.03 mm {0.0012 in}

3. Measure the cam lobe height at the two points as shown.

• If not as specified, replace the camshaft.

Standard height (mm) {in}


Camshaft	L8	LF, L3	L3 (with variable valve timing mechanism)
INT	40.79 {1.606}	42.12 {1.659}	42.44 {1.671}
EXH	41.08 {1.618}	41.08 {1.618}	41.18 {1.622}

Minimum height (mm) {in}


Camshaft	L8	LF, L3	L3 (with variable valve timing mechanism)
INT	40.692 {1.603}	42.022 {1.655}	42.342 {1.667}
EXH	40.982 {1.614}	40.982 {1.614}	41.082 {1.618}

4. Measure the journal diameters in X and Y directions at the two points (A and B) as indicated in the figure.

• If not as specified, replace the camshaft.

Standard diameter:

24.96-24.98 mm {0.9827-0.9834 in}

Minimum diameter:

24.95 mm {0.982 in}

5. Remove the tappet.

6. Position plasticgage atop the journals in the axial direction.

7. IInstall the camshaft cap. (See Camshaft Assembly Note.)

8. Remove the camshaft cap. (See Camshaft Cap Disassembly Note.)

9. Measure the oil clearance.

• If not as specified, replace the cylinder head.

Standard clearance:

0.04-0.08 mm {0.002-0.003 in}

Maximum clearance:

0.09 mm {0.0035 in}

10. Install the camshaft cap. (See Camshaft Assembly Note)

11. Measure the camshaft end play.

• If not as specified, replace the cylinder head or camshaft.

Standard end play:

0.09-0.24 mm {0.0035-0.0094 in}

Maximum end play:

0.25 mm {0.0099 in}

12. Remove the camshaft cap. (See Camshaft Cap Disassembly Note.)
