Measurement method.  



Using a thickness gauge, measure the clearance between the tappet and the base circle of 
camshaft.  



Record the out-of-specification valve clearance measurements. They will be used later to 
determine the required replacement adjusting tappet.  

Valve clearance 

Specification 

Engine coolant temperature: 20°C [68°F] 

Limit 

Intake: 0.10-0.30 mm (0.0039-0.0118 in.) 

Exhaust: 0.20-0.40 mm (0.0079-0.0157 in.) 

2. Turn the crankshaft pulley one revolution (360°) and align the groove with timing mark "T" 

of the lower timing chain cover. 

3. Check only valves indicated as shown in Fig. 7. [No. 4 cylinder: TDC/compression]. Measure the
