INSPECTION OF ENGINE
COMPONENTS
NOTE:
During and immediately after disassembly, inspect cylinder
block and head for evidence of water leakage or damage
and, after washing them clean, inspect more closely.
Wash all disassembled parts clean, removing grease,
slime, carbon and scales, before inspecting them to deter-
mine whether repair is necessary or not.
Be sure to de-scale the water jackets.
Use compressed air to clear internal oil holes and pas-
sages.
Do not disturb the set combinations of valves, bearings and
bearing caps, etc.
Have the sets segregated and identified.
Cylinder head
De-carbon cylinder head:
Deposits of carbon will be found on its combustion chamber sur-
faces and exhaust ports. Remember, overheating tendency and
loss of output are often due to excessive carbon accumulation.
De-carbon valves, too.
NOTE:
Do not use any sharp-edged tool to scrape off carbon. Be
careful not to scuff or nick metal surfaces when de-carbon-
ing. This applies to valves and valve seats, too.
