The cylinder head, though unsung, is the powerhouse’s crown jewel. This vital engine part sits atop, sealing the combustion chambers. Its design is critical, demanding precision and expertise.

Made of iron or aluminium (for lighter weight), it withstands immense heat and pressure. Key functions include:

Sealing & Shaping: Encloses cylinders, forming the combustion chamber.

Heat Management: Absorbs 70% of engine heat, requiring thermal insulation.

Air & Fuel Flow: Houses intake/exhaust ducts, valves, and injectors.

Valve Control: Often supports camshafts and related components.

This complex masterpiece ensures smooth engine operation, making it a truly crucial component.

Preventative Maintenance:

• Regular oil changes and filter replacements: This ensures clean oil lubricates components within the cylinder head, reducing wear and tear.
• Coolant flush and refill: Maintain the proper coolant level and quality to prevent overheating and corrosion.
• Air filter cleaning/replacement: Clean or replace air filters regularly to ensure clean air enters the engine, preventing harmful particles from reaching the cylinder head.
• Fuel system cleaning: Consider periodic fuel system cleaning to remove deposits that can affect performance and potentially harm the cylinder head.

Visual inspection: Look for leaks, cracks, or other signs of damage during routine maintenance checks.
