Head Gaskets:
Premature head gasket failure is a common issue on EJ series engines, especially those without updated designs. The manual will detail inspection and replacement procedures.
Timing Belt Tensioner:
Failure of the timing belt tensioner can lead to belt slippage or breakage, causing severe engine damage. Replacement with the belt is crucial.
Oil Leaks:
Rear main seal, oil pan gasket, and valve cover gaskets are prone to leaks.
Automatic Transmission:
Some models may experience torque converter shudder or shifting issues, often related to fluid degradation or solenoid issues.
ABS Sensors:
Wheel speed sensors for the ABS system can fail, triggering ABS warning lights.
