  • 0.023 kg
  • Engine group
  • 3 applications across TD and TAD series engines

🔌 Function

Provides the hardened sealing and heat-transfer surface against which the engine valve closes.

⚠️ Common Signs of Failure

  • Compression down on one cylinder, with hard starting or a misfire
  • Seat burnt, pitted or cracked, or found loose in the head
  • Valve clearance closing up repeatedly between services as the seat recedes
  • Valve sinking into the head so the correct contact width cannot be restored by refacing
  • Seat damage found alongside valve or piston damage during a head overhaul

🛠️ Service Notes

  • Valve seat 20459854 is also listed against the same three TD and TAD fitments, so measure the counterbore in the head and order by part number
  • Cut the seat and lap the valve as a matched pair, then check valve recession before the head goes back on
