- Lubricate new valve stem - with engine oil or assembly lube
- Insert new exhaust valve - into the guide from the combustion chamber side
- Install valve spring, retainer, and keepers - compress spring and secure keepers
- Lap the valve (if necessary) - apply lapping compound and rotate valve against seat to ensure sealing
- Check installed height - measure valve spring height; adjust with shims if needed
- Reinstall cylinder head - with new head gasket. Torque head bolts to specification
- Adjust valve clearance - set exhaust valve lash to OE specification (typically 0.35-0.45mm cold for 6SD1T)
- Start engine - check for smooth operation and correct valve train noise
Quality Control
- Material Verification: Alloy composition tested via spectrometer
- Dimensional Inspection: Head diameter, stem diameter, overall length, and keeper groove position verified
