1992 MITSUBISHI MIRAGE

Typical onset: 90,000-150,000 mi

Symptoms: White smoke from exhaust, sweet smell, Coolant disappearing with no visible leaks, Milky oil on dipstick or cap, Overheating despite thermostat/radiator replacement, Rough idle, misfires after warming up

Fix: Head gasket itself is 6-8 hours labor, but by the time owners notice on these, the head is often warped and block damage is done. Typical outcome is full engine rebuild (pistons, rings, bearings, crank polish, head resurface) at 25-35 hours shop time, or junkyard short block swap at 12-16 hours. Original cooling systems were marginal; one overheating event cooks everything.

Estimated cost: $2,800-5,500

Typical onset: 70,000-120,000 mi

Symptoms: Clunk when shifting from Park to Drive or Reverse, Severe vibration at idle that disappears when shifted to Neutral, Shifter feels loose or gates are hard to find, Visible sag of transmission when looking from underneath, Transmission hits crossmember over bumps

Fix: Rear transmission mount (rubber biscuit style) deteriorates and lets the trans drop 2-3 inches. Requires lifting trans with jack, 2-3 hours labor. Cheap part but access is tight. If ignored, can damage shift linkage and cooler lines. Often coincides with transmission oil cooler line fatigue cracking.

Estimated cost: $180-350

Typical onset: 80,000-140,000 mi

Symptoms: Transmission fluid puddle under car, usually passenger side, Burnt smell while driving, Slipping gears or delayed engagement after sitting, Red fluid spray on undercarriage, Low fluid level on dipstick despite recent service

Fix: Steel lines from transmission to radiator-mounted cooler rust through at unions or develop stress cracks where mount flexes them. Requires custom line fabrication or OEM lines (NLA, so often universal replacement). 2-3 hours with flush and refill. Catching it early prevents transmission damage; most owners don't notice until major fluid loss causes internal wear.

Estimated cost: $280-550

Symptoms: Engine cranks but won't start, especially when tank is low, Stalling during acceleration or uphill driving, Surging at highway speed, Starts fine cold, dies after 10-15 minutes, Fuel pump sounds loud or whines

Fix: In-line fuel filter under car, often never changed in 30+ years. Rust from tank combines with sediment; complete clog strands owners. Filter replacement is 0.5 hours, but pump screen may also be plugged requiring tank drop (4-6 hours). Preventive replacement every 30k miles would eliminate this but almost nobody does it on these old econoboxes.

Estimated cost: $85-650

Typical onset: 100,000+ mi

Symptoms: Door won't latch closed, bounces open, Must slam door repeatedly to engage, Door feels closed but warning light stays on, Latch stuck, door won't open from inside or outside, Plastic components visible in door jamb area broken

Fix: NHTSA recall was issued but many never got fixed. Plastic latch pawl wears or breaks. Requires door panel removal and latch assembly replacement. 1.5-2 hours labor. Aftermarket latches are hit-or-miss quality; used OEM from junkyard is better bet. Not safety-critical but annoying and can leave you locked out or with door flying open.

Estimated cost: $150-320

Typical onset: 80,000+ mi

Symptoms: Oil puddle under car after parking overnight, front-center, Burnt oil smell while driving, Oil coating on exhaust manifold side of engine, Oil consumption between changes, Visible seepage around top of engine block

Fix: Valve cover gasket hardens and cam/crank seals leak on all examples this age. Valve cover is easy, 1 hour. Front main seal requires timing belt off (add 2 hours). Rear main requires trans out (7-10 hours). Most folks live with minor seepage and just monitor levels because labor exceeds car value for rear seal. Do valve cover and front while doing timing belt.

Estimated cost: $120-1,200
