• 0.014 kg
• 60 applications across TAMD, AD, D, TMD, KAMD and MD engines

🔌 Function

Provides the hardened landing the valve closes against, sealing the combustion chamber and conducting heat out of the valve head into the head casting.

⚠️ Common Signs of Failure

• Compression down on one cylinder with no improvement from an oil test
• Valve clearances closing up between services as the valve sinks
• Burnt or pitted seating band visible when the valve is lifted
• Seat recessed into the head, or a crack running from seat to port
• Hard cold starting with a misfire that clears as the engine warms

🛠️ Service Notes

• Standard seats only suit a head that has not been cut for oversize — check what is recorded for the head before ordering
• Renew the valve guides at the same time if there is stem play, or the new seat will wear as the old one did
• Reset the valve clearances once the head has been rebuilt and run
