The 1992 Eclipse, especially the 4G63-powered turbo models, is a tuner favorite but suffers from catastrophic crankwalk on abused examples, fragile automatic transmissions, and typical 30-year-old rubber/plastic decay. Non-turbo 1.8L and 2.0L models are more durable but still share transmission and age-related gremlins.
Crankshaft Thrust Bearing Failure (Crankwalk) — Turbo 2.0L 4G63
Common · high severityTypical onset: 80,000-150,000 mi
Symptoms: Excessive clutch pedal free-play that changes with engine temp, Hard shifting into reverse or first gear when warm, Metallic grinding or knocking from lower engine block, Clutch engagement point drifts outward over time
Fix: Engine-out teardown, crankshaft replacement or machining, new thrust bearings, full gasket set. Typically 18-24 hours labor plus machine work. Often triggers a full rebuild if oil starvation or detonation damage is present.
Estimated cost: $3,500-6,500
Automatic Transmission Failure (F4A33)
Common · high severityTypical onset: 60,000-120,000 mi
Symptoms: Slipping on 2-3 upshift or no third gear engagement, Delayed or harsh engagement from Park or Neutral, Burnt ATF smell, dark fluid color, Check engine light with shift solenoid codes
Fix: Chrysler-sourced F4A33 is notoriously weak, especially behind the turbo. Rebuild kits help temporarily, but used or remanufactured units are typical fix. Remove/install is 8-10 hours; rebuilds add another 12-16 hours. Many owners swap to manual.
Estimated cost: $1,800-3,200
Head Gasket Failure — Turbo 2.0L
Occasional · high severityTypical onset: 70,000-130,000 mi
Symptoms: White smoke from exhaust on cold start, Coolant loss with no visible leaks, Oil in coolant reservoir or milky dipstick, Overheating under boost or sustained highway driving
Fix: Factory MLS gasket and ARP studs are the permanent fix; OEM multi-layer style fails repeatedly if boost is raised. Head must be checked for warpage. 12-16 hours labor with timing belt, water pump, and seals done simultaneously.
Estimated cost: $1,500-2,800
Transmission and Engine Mounts
Common · medium severityTypical onset: 60,000-100,000 mi
Symptoms: Clunking when shifting or lifting off throttle, Excessive engine movement visible from engine bay during acceleration, Vibration at idle that worsens with A/C on, Shifter slop or difficulty finding gears on manual trans
Fix: Hydraulic mounts collapse over time; solid aftermarket options available but increase NVH. Front, rear, and transmission mount replacement is 3-5 hours combined. Original rubber designs don't last in turbo cars.
Estimated cost: $400-750
Fuel System Decay — Lines, Filter, Pump
Occasional · medium severityTypical onset: Not mileage-driven — age and ethanol exposure
Symptoms: Fuel smell in cabin or garage, especially when hot, Hard starting after sitting, long crank times, Lean stumble or hesitation under boost (turbo models), Visible corrosion or seepage on steel fuel lines under chassis
Fix: Rubber hoses crack, steel lines rust through in salt states, and in-tank pump socks clog. Full fuel system refresh (pump, filter, lines, damper) runs 6-10 hours depending on line routing. Pump alone is 2-3 hours (tank drop).
Estimated cost: $600-1,400
Electrical Gremlins — Alternator, Ignition, Grounds
Occasional · low severitySymptoms: Intermittent no-start, dome light dims while cranking, Gauge cluster flickers or tach bounces at idle, Random stalling when hot, restarts after cooling, Battery dies overnight despite new battery
Fix: Corroded chassis grounds behind headlights and under intake manifold are common culprits. Alternator brushes wear out; ignition switches crack internally. Diagnosis is 1-2 hours; fixes vary from $50 ground cleaning to $300-500 alternator or switch replacement.
Estimated cost: $150-650
Rust — Rear Quarter Panels and Strut Towers
Common · medium severitySymptoms: Bubbling paint behind rear wheel arches, Visible perforation at bottom of quarter panels, Crunchy metal or rust scale when pressing on strut tower edges, Water intrusion into trunk from quarter panel seams
Fix: Sheet metal rust-through requires welding and panel replacement for proper repair. Strut tower damage compromises suspension mounting integrity. Rust repair is bodywork-intensive; expect 20+ hours for both quarters or tower patches. Many examples are too far gone.
Estimated cost: $2,000-5,000
Buy a non-turbo manual for a reliable daily; turbo models are project cars requiring deep pockets or DIY skills, especially if the crankshaft hasn't been addressed yet.
