1992 CHEVROLET METRO

Typical onset: 80,000-130,000 mi

Symptoms: white smoke from exhaust, coolant consumption with no visible leaks, milky oil on dipstick, overheating under load, hard starting when warm

Fix: Requires cylinder head removal, resurfacing (usually warped 0.008-0.015 inches), new head gasket set, timing belt replacement while apart, coolant flush. 8-10 labor hours at indie shop. The small 3-cylinder runs hot and the thin head casting warps easily. Many shops recommend replacing the thermostat and water pump at the same time since you're in there.

Estimated cost: $800-1,400

Typical onset: 90,000-140,000 mi

Symptoms: slipping between 1st and 2nd gear, delayed engagement when cold, no reverse or weak reverse, shuddering on light throttle, metal shavings in pan during fluid change

Fix: The 3-speed auto is the weak link in these cars—clutch packs wear, valve body passages clog, and the torque converter rarely survives past 120k. Rebuild runs 12-16 hours and often not worth it given vehicle value. Used transmission swap is 6-8 hours but finding good cores is difficult. Many owners convert to manual transmission from a donor car (16-20 hours with all fabrication).

Estimated cost: $1,200-2,200

Typical onset: 100,000-150,000 mi

Symptoms: visible rubber separation between inner and outer ring, vibration at idle that worsens with RPM, serpentine belt walking off pulleys, rough running that feels engine-related, squealing even with new belt

Fix: The rubber damper layer delaminates and the outer ring starts wobbling or spinning independently. If it comes apart completely, it can take out the timing belt and cause valve damage. Replacement requires removing the crankshaft bolt (often seized, sometimes requires impact gun and breaker bar together), 2-3 hours labor. Always inspect during timing belt service on these.

Estimated cost: $250-450

Typical onset: 60,000-110,000 mi

Symptoms: transmission fluid spots under car near radiator, fluid level dropping without visible leak at pan, pink/red fluid dripping from front of vehicle, transmission running hot, burnt smell from transmission

Fix: Steel cooler lines rust through where they run along the subframe and connect to the radiator. Often multiple pin-hole leaks. Requires replacement of both lines, sometimes radiator if internal cooler is compromised. 2-3 hours labor, but if not caught early, you'll need a transmission rebuild from running low on fluid. Check these lines annually in salt-belt states.

Estimated cost: $200-400

Typical onset: 70,000-120,000 mi

Symptoms: high engagement point near top of pedal travel, clutch pedal staying on floor occasionally, grinding when shifting into first or reverse, fraying visible at cable ends, inconsistent clutch feel day to day

Fix: Cable-operated clutch stretches and frays over time. The adjuster mechanism at the transmission wears and won't hold adjustment. Replacing the cable is straightforward, 1.5-2 hours. While you're there, inspect the clutch fork and throwout bearing through the inspection hole—if the clutch itself is original and over 80k, consider doing the full clutch kit since labor overlaps significantly (add 4-5 hours for full clutch).

Estimated cost: $150-280

Typical onset: 150,000+ mi

Symptoms: ticking/tapping noise from valve cover that increases with RPM, loss of power especially at highway speeds, poor fuel economy suddenly declining, check engine light with cam position codes, rough idle that smooths out at 2000+ RPM

Fix: Owners who skip oil changes or use cheap oil see accelerated cam lobe wear on the tiny 1.0L. Requires head removal, camshaft replacement, often new lifters and valve adjustment, timing belt replacement. 10-12 hours labor. Usually discovered during head gasket job. Given the age and value of these cars, many shops recommend looking for a used replacement engine instead (8-10 hours for swap).

Estimated cost: $1,000-1,800
