Piston: Testing and Inspection
Inspect Ring Groove Clearance

Using a feeler gauge, measure the clearance between new piston ring and the wall of the piston ring groove.
Ring groove clearance: 

No. 1: 0.0.040 - 0.080 mm (0.0016 - 0.0031 inch)
No. 2: 0.030 - 0.070 mm (0.0012 - 0.0028 inch)

If the clearance is not as specified, replace the piston.
