Cleaning and Inspection
CLEANING
Clean piston using suitable solvent.
Use a putty knife or scraper to help clean carbon off of the top of the piston.
Do not use a power wire brush to clean the piston skirt, crown, or piston ring grooves; it will remove metal.
If using a ring groove scraper, be careful not to remove metal from the piston ring lands.

^
Hole or crack in top of piston caused by preignition or foreign object damage.
^
Excess wear in ring lands indicated by visible steps worn in ring lands.
^
Scoring or gouges on piston skirt or crown.
^
Looseness between piston and piston pin.
