The 1992 Legacy with the 2.2L EJ22 is one of Subaru's most durable powertrains, but even good engines need head gaskets eventually. These cars rust badly underneath in salt states, and transmission mounts fail predictably.
Head Gasket Failure (External Seepage)
Common · medium severityTypical onset: 120,000-180,000 mi
Symptoms: Oil or coolant weeping from cylinder head seam, visible on block, Slight oil consumption or coolant smell, rarely catastrophic overheating, Crusty deposits on lower engine block sides
Fix: External head gasket leak typical for EJ22. Both gaskets, resurface heads, timing components, fluids. 8-10 labor hours. Do cam seals, valve cover gaskets, water pump while in there.
Estimated cost: $1,200-1,800
Transmission Mount Collapse
Common · low severityTypical onset: 80,000-140,000 mi
Symptoms: Clunk on acceleration or deceleration, Excessive shifter vibration in gear, Visible tearing or separation of rubber mount body
Fix: Rear transmission mount (pitch stopper) tears and collapses. Straightforward replacement, 1-1.5 hours. OEM or aftermarket available.
Estimated cost: $150-280
Subframe and Rear Control Arm Rust
Common · high severitySymptoms: Rust perforation on rear subframe crossmember, Control arm mounting points crumbling or separating, Clunking over bumps, misalignment that won't hold
Fix: Salt-belt cars rust severely in rear subframe and control arm pickup points. Structural welding or subframe replacement required if compromised—expensive and labor-intensive, 6-12+ hours depending on damage severity.
Estimated cost: $800-2,500
Fuel Tank Strap and Filler Neck Corrosion
Occasional · medium severitySymptoms: Fuel smell near rear of car, Tank sagging or visibly corroded straps, Leaking at filler neck junction from rust-through
Fix: Straps and filler neck rust in road salt areas. Related to NHTSA recall but often seen beyond recall coverage age. Tank drop, new straps, filler neck if perforated. 2-3 hours labor.
Estimated cost: $300-600
Manual Transmission Synchro Wear (2nd Gear)
Occasional · medium severityTypical onset: 150,000-220,000 mi
Symptoms: Grinding or difficulty engaging 2nd gear when cold, Synchro crunch on aggressive 1-2 or 3-2 shifts, Progressively harder to shift into 2nd without double-clutching
Fix: Second gear synchro wears first in these 5-speeds. Requires transmission removal and rebuild. 8-10 hours labor plus internal parts and bearings.
Estimated cost: $1,200-2,000
Exhaust System Rot (Y-Pipe and Muffler)
Common · low severityTypical onset: 100,000-180,000 mi
Symptoms: Loud exhaust note, especially on startup, Visible holes or separation at Y-pipe flex section, Rattling from loose heat shields or failing hangers
Fix: Exhaust rusts from cat-back, Y-pipe flex joint fails. Replacement parts readily available. 1.5-2.5 hours for Y-pipe or cat-back section.
Estimated cost: $250-550
Buy it if rust-free and maintained; the EJ22 will outlast the body, but avoid salt-state examples unless undercarriage is inspected and solid.
