SUBARU HEAD GASKETS AND WHY THEY FAIL
Share
Subaru head gaskets are crucial components in Subaru engines, particularly in older models that are known for head gasket failure issues. The head gasket seals the space between the engine block and the cylinder head, preventing coolant and oil from mixing while maintaining compression in the combustion chamber. When a head gasket fails, it can result in various engine problems, including coolant leaks, loss of compression, engine overheating, and even complete engine failure if not promptly addressed.
Common Causes of Head Gasket Failure:
- Overheating: Subaru engines, particularly those with the 2.5L boxer engine, are susceptible to overheating. This can warp the cylinder head and damage the gasket, making it one of the leading causes of head gasket failure.
- Design Flaws: Some Subaru engines, especially the early 2.5L SOHC and DOHC engines found in models from the late 1990s to late 2000s, have designs that make them more prone to gasket failure. The materials used in the engine block and cylinder head, as well as specific sealing issues, contribute to this vulnerability.
-
Age and Wear: Over time, gaskets can deteriorate due to the constant thermal expansion and contraction caused by engine heat, eventually leading to leaks or complete failure.
Symptoms of a Failed Head Gasket:
Signs of a failing head gasket include overheating, oil residue in the cooling system, and oil leaks between the cylinder head and the engine block.
