Problem overview

Some Subaru Impreza owners report experiencing severe engine failure due to blown engines caused by significant oil leaks. This issue often results from internal damage due to overheating or loss of oil pressure, leading to component failure. A common cause of such engine failure is running out of oil, which results in loss of lubrication. Additionally, some owners have noted that problems with the charging system can create corrosive conditions affecting components like gaskets. The damage severity may necessitate a complete engine replacement or even prompt considerations of purchasing a new vehicle. It is essential for owners to address the root cause of the oil leak to prevent similar issues with a new engine. Upgrading to OEM gaskets from turbo engines may also help mitigate problems, particularly in turbocharged models. In cases of engine failure, assessing the damage and considering options like engine replacement or disclosing the vehicle's condition if selling is crucial.
