Common Issues with Subaru Engines
Like any engine type, Subaru engines are prone to some issues. Knowing these problems can help you in maintaining your engine’s performance and detecting any issues early enough. Some of the common issues include:
- Head gasket issues: This problem is common in the EJ engine series, and it’s caused by the gasket’s inability to withstand engine pressure, leading to oil and coolant leaks.
- Timing belt issues: The timing belt is essential in engine operation, and any issues with it could lead to engine failure. Subaru recommends a change of timing belt every 105,000 miles.
- Piston ring failure: This problem is more prevalent in turbocharged Subaru engines and could lead to engine knock, oil consumption, and power loss.
