🔌 Function

Closes the top of the cylinders and carries the valves, seats, guides and gas passages, containing combustion pressure and routing coolant around the ports.

⚠️ Common Signs of Failure

  • Coolant loss with no external leak, or bubbles and pressure in the header tank
  • White smoke or coolant in the oil after a gasket failure
  • Compression loss, hard starting and low power on one cylinder
  • Cracks between valve seats or into a coolant passage
  • Head face corroded, eroded or out of flat on measurement

🛠️ Service Notes

  • Check the head face for flatness and pressure test for cracks before deciding whether a used head can be saved
  • Renew the head gasket, head bolts where they are stretch type, and the valve stem seals, and check liner protrusion before fitting
  • Establish why the previous head failed, since a warped head is usually the result of an overheat that needs its own investigation
