What is the 1996-1999 Subaru Legacy EJ25 DOHC (Phase I) internal head gasket failure?
The first 2.5L boxer in the Legacy, the EJ25D DOHC (Phase I), used a composite head gasket that fails internally around the 100,000-mile mark. Unlike the later external-leak variant, this failure lets coolant and combustion gases mix, causing loss of compression, coolant in the o… Repairs typically run $1,500-$2,800. Severity: high.
What is the 1996-1999 Subaru Legacy Interference engine: neglected timing belt destroys valves?
The DOHC EJ25 and the 1997-and-later SOHC EJ boxers are interference designs - if the rubber timing belt breaks or jumps teeth, the pistons strike open valves and bend them, often ruining the heads. (The pre-1997 SOHC EJ22 is non-interference; the change to interference on the SO… Repairs typically run $500-$4,000. Severity: high.
What is the 1990-1999 Subaru Legacy 4EAT AWD torque bind (Duty C solenoid / transfer clutch)?
Automatic-transmission Legacys use an electronically controlled transfer clutch (governed by the Duty C solenoid) to send torque to the rear wheels. When the clutch pack sticks engaged or the Duty C solenoid gets dirty/sticky, the AWD stays locked on dry pavement and cannot relie… Repairs typically run $300-$2,500. Severity: medium.
