1984 ALFA ROMEO SPIDER

Typical onset: all mileages—age-related deterioration

Symptoms: hard starting when cold or hot, rough idle and stumbling, poor fuel economy, complete no-start condition, black smoke from exhaust

Fix: SPICA pumps require specialized knowledge now rare in the field. Rebuild costs 8-12 hours if you find someone competent; many owners convert to Weber carburetors (2 DCOE or single downdraft) which takes 6-10 hours including tuning. Alternatively, standalone EFI conversions are becoming popular.

Estimated cost: $1,800-3,500

Typical onset: failure typically when belt exceeds 50,000 mi or 5 years

Symptoms: sudden loss of power while driving, engine won't turn over or turns too freely, bent valves confirmed on compression test, catastrophic engine damage requiring rebuild

Fix: This is an interference engine—belt failure means bent valves at minimum, often damaged pistons. Prevention is 4-5 hours for timing belt/water pump/tensioner service. Repair after failure: cylinder head removal and valve work adds 12-16 hours, full short block work if pistons damaged pushes to 20-28 hours.

Estimated cost: $3,500-7,000

Typical onset: 60,000-90,000 mi

Symptoms: excessive driveline clunk on throttle application, vibration through shifter and floor, difficulty engaging gears cleanly, visible engine movement in bay during rev

Fix: Rubber mounts harden and tear with age. Transmission mount is the worst offender and relatively accessible at 1.5-2 hours. Engine mounts (2) add another 2-3 hours. Should all be done together for best results.

Estimated cost: $400-800

Typical onset: 70,000-120,000 mi

Symptoms: oil pooling under rear of engine, oil dripping onto bellhousing, clutch contamination in severe cases, constant need to top off oil between changes

Fix: Rear main seal requires transmission removal: 8-10 hours total. Oil pan gasket is easier at 3-4 hours but pan bolts often break requiring extraction. Cork gaskets were original; modern rubber replacements last longer but installation technique matters.

Estimated cost: $800-1,800

Symptoms: intermittent gauge failures, random stalling or misfires, lights flickering or dimming, starter engagement issues, accessories failing unpredictably

Fix: Italian wiring of this era used marginal connectors and inadequate ground points. Diagnosis is time-consuming (2-6 hours depending). Common fixes: cleaning all engine bay grounds, replacing corroded bullet connectors, checking starter and alternator connections. Preventive rewiring of problem circuits recommended.

Estimated cost: $200-900

Typical onset: 100,000+ mi or after severe overheating

Symptoms: persistent coolant loss with no external leaks, white exhaust smoke, coolant in oil or vice versa, overheating that doesn't respond to new thermostat/radiator

Fix: These aluminum heads can crack between exhaust valve seats, especially if overheated. Diagnosis via pressure test. Repair requires head removal (8 hours), magnaflux inspection, and either welding repair or replacement head, plus machining. Total 14-20 hours if head is rebuildable.

Estimated cost: $2,500-4,500
