Fault Diagnosis: Cylinder Head

The cylinder head is another major component in the engine block.

Before we start revising the cylinder head, it is first placed in a “pressure bath”. This machine ensures that the cylinder head is submerged into a water bath at 60°C, after which it is subjected to pressure. If a cylinder head has cracks, these become apparent via air bubbles in the water bath.

By using this standard checking procedure we avoid potential leaks in the cylinder head, as well as other problems like pressure build-up and water leakage in pistons. The cylinder head is then revised and fitted with new parts.
  • Valves
  • Valve seats
  • Valve guides
  • Valve caps

After comprehensive revision, it is also important to re-level the cylinder head to realise perfect passage. By levelling the cylinder block and the engine block, we avoid risks and ensure 100% compatibility with the original specification.
