Can a Single Overheat Damage the Cylinder Head Gasket?

[Guzman]

Short-term overheating will not damage the cylinder head gasket. Prolonged engine operation: When the engine operates under heavy load for extended periods, frequent detonation combustion can occur, leading to localized high temperatures and pressure within the cylinders, which can erode the head gasket. Improper bolt installation: If cylinder head bolts are tightened without following specified procedures, uneven torque can prevent the gasket from seating properly between the cylinder block and head, resulting in gas leakage. Excessive advance angle: Excessive ignition advance or fuel injection advance angles can cause excessively high cycle pressures and temperatures. Poor gasket quality: Low-quality gaskets with uneven thickness, trapped air pockets in the sealing edges, uneven asbestos distribution, or loose wrapping edges.
