🔌 Function

Provides a precision replacement seating surface in a cylinder head that has been machined for the 0.20 mm oversize repair seat. Machine and install the seat to the correct interference, depth, concentricity and valve-contact width; confirm valve recession and sealing before cylinder-head assembly.

⚠️ Common Signs of Failure

• Loss of compression or uneven cylinder compression readings
• Burnt, pitted or recessed sealing face causing valve leakage
• Rough idle, misfire or hard starting on the affected cylinder
• Seat loosening or dropping into the combustion chamber, causing severe internal damage
• Excessive valve recession requiring repeated valve clearance adjustment

🛠️ Service Notes

• Seat inserts are an interference fit in the head, so the counterbore has to be clean, round, flat and square before a new seat goes in; normal practice is to chill the insert and warm the head so it drops into place rather than forcing it
• This is machine-shop work — the seat must be cut concentric with the valve guide after installation, so check or renew the guides at the same time and cut the seat angles once the insert is secure
• Inspect the head casting for cracks and for a pounded or spread counterbore before committing to a new seat; a seat that has come loose has usually damaged its pocket
• Use the interference fit, insert size and seat angles specified for your engine rather than any general figure, as they differ between heads
• Check each valve on its finished seat for an even contact band right the way round, and confirm valve position and any permitted recession against the workshop manual for your engine
