After removal of cylinder head, suction and exhaust valve must inspected thoroughly.
Checks/ Inspection of suction valve and exhaust valve
Following things must be checked:
- Both the valves must be checked for sulphuric acid corrosion and bend of the suction/ exhaust valve stem, and measure the dimensions.
- Check for high temperature corrosion of the valve poppet.
Why valve poppet tip or exhaust valve top should be checked/ measured?
Correct the valve poppet tip part upon carefully checking it because if it becomes too thin, it may be chipped and the pieces may enter the combustion chamber and turbocharger causing damage.
