The 1993-2001 Impreza with the 2.2L EJ22 is one of Subaru's most durable engines, but head gaskets remain the Achilles' heel. These are solid daily drivers that rust in salt states and suffer from typical AWD drivetrain wear.
Head Gasket Failure (External Coolant Leaks)
Common · medium severityTypical onset: 100,000-150,000 mi
Symptoms: Coolant seepage from bottom of engine, visible as white or green residue, Slow coolant loss without visible external leak at hoses, Sweet smell from engine bay after driving, No overheating or mixing of coolant and oil in most cases
Fix: External weep only, not the catastrophic internal failure seen on 2.5L engines. Requires pulling engine or lifting it significantly. Both gaskets, timing components, water pump, and resurfacing if warped. 10-14 hours labor for full job done right.
Estimated cost: $1,200-1,800
Automatic Transmission Failure (Phase I Models)
Occasional · high severityTypical onset: 120,000-180,000 mi
Symptoms: Delayed engagement into Drive or Reverse, Slipping between gears, especially 2nd to 3rd, Burnt transmission fluid smell, Check engine light with transmission codes
Fix: 4EAT transmission in 1993-1996 models notorious for duty solenoid C and clutch pack wear. Rebuild requires 8-12 hours, but used replacement often more cost-effective. External cooler addition highly recommended during any work.
Estimated cost: $1,800-3,200
Rear Wheel Bearing Failure
Common · medium severityTypical onset: 80,000-130,000 mi
Symptoms: Humming or growling noise that increases with speed, Noise changes pitch during turns, Vibration felt through seat at highway speeds, ABS light may illuminate if bearing collapses
Fix: Pressed-in sealed bearings that require hub assembly removal. More labor-intensive than typical bolt-on designs. 2-3 hours per side. Both sides often fail within 20k miles of each other.
Estimated cost: $300-500 per side
Front Crossmember Rust (Salt Belt States)
Common · high severitySymptoms: Visible surface rust and scaling on front subframe, Perforation or holes in crossmember near control arm mounts, Clunking from front suspension over bumps, Failed state inspection in rust-check states
Fix: Front crossmember collects salt and mud, rusts from inside out. Replacement requires complete front suspension disassembly. 8-10 hours labor. Used JDM or southern-car parts often necessary as new not available.
Estimated cost: $800-1,500
Timing Belt and Water Pump (Maintenance Item)
Common · high severityTypical onset: 60,000-105,000 mi intervals
Symptoms: Squealing from front of engine on cold starts, Coolant weeping from water pump weep hole, No symptoms until catastrophic failure
Fix: Non-interference engine means valve damage unlikely if belt breaks, but you're stranded. Replace every 105k or 10 years. Always do water pump, tensioner, and idlers simultaneously. 3-4 hours labor.
Estimated cost: $500-750
Fuel Filler Neck Rust and Separation
Occasional · medium severitySymptoms: Fuel smell near rear of vehicle, Check engine light for evaporative emission system leak, Visible rust or separation at filler neck to tank connection, Fuel gauge reading erratically
Fix: Filler neck rusts where it meets tank, especially in salt states. NHTSA recall addressed some but not all years. Requires fuel tank drop. 2-3 hours labor. OE parts discontinued, aftermarket quality variable.
Estimated cost: $300-600
Front Strut Tower Rust (Severe Cases)
Rare · high severitySymptoms: Visible rust bubbling under battery tray area, Perforation near strut mounting points, Clunking or popping from suspension, Total structural failure in extreme neglect cases
Fix: Primarily passenger side under battery. Surface rust manageable with wire wheel and rust converter. Structural perforation requires welding or replacement of entire tower section. 6-10 hours bodywork if repairable.
Estimated cost: $500-2,000+
Buy it if rust-free and manual: the EJ22 is one of Subaru's most reliable engines and will run 250k+ with basic maintenance. Walk away from rusty examples or automatic transmissions showing any slippage.
