🔌 Function

The valve seat forms the fixed sealing surface against which the oil system valve closes, allowing the valve to regulate or relieve lubricating oil pressure. A true, undamaged seat is essential for the valve to seal fully and hold the correct oil pressure.

⚠️ Common Signs of Failure

• Low or fluctuating engine oil pressure readings
• Oil pressure warning light or alarm activating under load or at idle
• Visible pitting, scoring or wear ridges on the sealing face
• Valve failing to seat fully, allowing internal oil bypass
• Oil seepage or loss of pressure after the valve assembly has been disturbed

🛠️ 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
