CYLINDER HEAD GASKET 27-8041151 REC67F-11181-03
Read the review
Description
Function and technical context
The head gasket is a critical component that ensures a tight seal between the cylinder head and the engine block, preventing coolant and combustion gas leaks that could compromise the operation of the engine. This part works in the cooling and sealing system of the combustion chambers, subjected to permanent cycles of pressure and temperature. Its correct installation is essential to maintain the integrity of the internal pressure and cooling systems, preventing water from entering the cooling ducts and loss of compression in the combustion chamber.
When to replace this part?
Symptoms of wear or deterioration include visible loss of coolant with no apparent origin, overheating of the engine during navigation, or the presence of milky emulsion in the oil (a mixture of water and lubricant that indicates water infiltration into the crankcase). It is recommended to inspect this gasket at each annual maintenance check or after intensive periods of use. Preventive replacement of the head gasket prevents costly repairs at sea and ensures engine reliability on long voyages.
