Subaru Legacy head gasket and engine block replacement issues with documented ongoing problems on Subaru Legacy

Some Subaru Legacy owners report experiencing head gasket issues, particularly in models from 1996 to 2004 with 2.5L engines, which can lead to external oil leaks, internal coolant leaks, and warped or cracked heads. Symptoms of a blown head gasket may include poor engine performance or complete engine failure, often attributed to factors such as low-quality gasket material, inadequate maintenance, and improper head torque procedures. The recommended repair method involves removing the engine for a thorough repair to ensure longevity. To prevent these issues, owners are advised to maintain good engine practices, follow proper torque procedures during repairs, and address coolant electrolysis concerns promptly. Vigilance regarding these potential problems can help Subaru Legacy owners mitigate risks and extend the life of their vehicles.
