Piston Ring Inspection
- Using the piston, press the piston ring parallel into the cylinder to 43.9 mm {1.73 in} from the upper end of the cylinder block.
- Measure the piston ring end gap using a feeler gauge.
- If it exceeds the maximum specification, replace the piston ring.

Second: 0.18-0.28 mm {0.008-0.011 in}
Oil (Rail): 0.10-0.35 mm {0.004-0.013 in}
Maximum piston ring end gap
Top: 0.35 mm {0.014 in}
Second: 0.45 mm {0.018 in}
Oil (Rail): 0.52 mm {0.020 in}
