Inspect the Piston and the Piston Rings

  1. Check the piston for wear and other damage.

  2. Check that the piston rings are free to move in the grooves and that the rings are not broken.

Inspect the Clearance of the Piston Ring

  1. Remove the piston rings and clean the grooves and the piston rings.

    (1) Feeler gauge
    (2) Piston ring
    (3) Piston grooves

  2. Fit new piston rings (2) in the piston grooves (3).

  3. Check the clearance for the piston ring by placing the 8H-8581 Feeler Gauge (1) between piston groove (3) and the top of piston ring (2). Refer to Specifications, "Piston and Rings" for the dimensions.

    Note: On the “C2.2/3024C” Turbocharged engines, the pistons have a tapered top groove and the piston ring is wedged. The clearance for the top piston ring cannot be checked by the above method when this occurs.

Inspect the Piston Ring End Gap

    (1) Feeler gauge
    (2) Piston ring

  1. Clean all carbon from the top of the cylinder bores.

  2. Place each piston ring (2) in the cylinder bores.

  3. Use the 8H-8581 Feeler Gauge (3) to measure piston ring end gap. Refer to Specifications, "Piston and Rings" for the dimensions.

    Note: The coil spring must be removed from the oil control ring before the gap of the oil control ring is measured.
