What Is The Root Cause Behind The Components Failure?
The two most common reasons head gaskets are placed under stress are overheating in the engine and detonation. When your engine overheats, it causes the cylinder head and block to expand, as described earlier. The problem is, there are many potential issues that can cause the assembly to overheat. For example, the problem could be caused by a leaking water pump, clogged radiator, or a lack of oil. If your mechanic simply replaces the head gasket without resolving the root cause of the original part’s failure, the replacement will also fail. Given that labor and parts may cost several hundreds of dollars, the underlying issue must first be fixed. Detonation occurs when the air-fuel mixture in the cylinder pre-ignites (i.e. it ignites before the spark plug has a chance to fire). The early ignition causes the piston to slam against the walls of the cylinder. This causes a knocking sound and can eventually destroy the piston, leading to the head gasket’s failure. This problem can occur for
