Subaru Impreza suspected head gasket issue, engine replacement recommended on Subaru Impreza

Some Subaru Impreza owners report experiencing head gasket issues, particularly with the 2.5 Liter SOHC engine in model years from late 1999 to 2004, which can lead to symptoms such as engine overheating and unusual performance. These problems necessitate prompt attention to avoid costly repairs or the need for engine replacement. While head gasket replacement is often a viable solution, some owners find that extensive damage may require a complete engine replacement. The duration of head gasket replacement can vary based on the model and technician's experience. Regular maintenance and immediate response to head gasket symptoms are crucial in preventing severe issues that could lead to engine replacement. Owners are advised to consult a qualified technician for a thorough assessment and to carefully consider the costs and benefits of repair versus replacement based on the damage extent and vehicle condition.
