  • The engine head is usually referred to as “cylinder head";
  • Always check the oil and water levels;
  • Always follow the motherhouse maintenance requirements


The engine head, also called cylinder head, plays an essential role in the exploitation of the engine gas in the combustion chamber, most of all for the two-stroke engines. Made of cast iron or aluminium, it basically consists of a lid fixed on the short-block by means of screws. The head covers the cylinders in the upper part, thus ensuring the right compression ratio, preventing the internal gas from escaping.

Symptoms of the cylinder head failure. There are many signs of imminent failure of the engine head: water in the engine oil, high consumption of engine coolant, oil in the cooling system expansion tank, difficulty in starting the cylinders during the engine ignition phase, white smoke coming from the exhaust of the engine at startup. Causes for wear and damage to the cylinder head. Malfunction of the cooling system leading to the burning of the gasket between the cylinder head and the block; cracks and deformation also caused by high-temperatures; burned valves or their seats not properly lined-up. Steps to avoid damage to the cylinder head. Maintenance shall be performed in accordance with the manufacturer’s manual for service and maintenance, especially when dealing with engines powered by CNG or LPG. Always check the engine’s water and oil levels.
